PHP - Generate A New Array From Another Array
public function getEventTypes()
{ return array( 1=>array('Exhibition', 1), 2=>array('Wedding', 1), 3=>array('Business', 1), 4=>array('School Trip', 0), 5=>array('Birthday', 0), 6=>array('Concert', 1), 7=>array('Sporting Event', 1), 8=>array('Training', 0), 9=>array('Conference', 1), 10=>array('Other', 1), ); } I now want to generate a new array from this array as follows: 1) must retain the existing key 2) must be single dimensional and the value of each element will be value[0] 3) must only contain the array elements where value[1] = 1 So for example the generated array should be as follows: public function getActiveEventTypes() { return array( 1=>'Exhibition', 2=>'Wedding', 3=>'Business', 6=>'Concert', 7=>'Sporting Event', 9=>'Conference', 10=>'Other', ); } Similar Tutorials$bl = array(); $link1 = array_rand($cds); $link2 = array_rand($cds); $link3 = array_rand($cds); $link4 = array_rand($cds); $A = 0; while (!in_array($link1, $bl)){ $link1 = array_rand($cds); $bl[$A] = $link1; $A++; } while (!in_array($link2, $bl)){ $link2 = array_rand($cds); $bl[$A] = $link2; $A++; } while (!in_array($link3, $bl)){ $link3 = array_rand($cds); $bl[$A] = $link3; $A++; } while (!in_array($link4, $cds)){ $link4 = array_rand($cds); $bl[$A] = $link4; $A++; } echo $link1; echo $link2; echo $link3; echo $link4; Pretty much I'm trying to generate 4 number's between the min and max of an array but I don't want any duplicates. So it checks if the number exists in a bl array if it does it generates another number, well thats the theory. Doesn't work like that though. Here is how I get categories for article listing. Article can be written in several categories at once. So I have this code: Code: [Select] $category = '1,5,23,46'; //Category IDs $get_cats = explode("," , $category); $cats = ""; for ($i = 0; $i<count($get_cats); $i++ ) { $cat = trim($get_cats[$i]); $catSlug = get_value_of($cat, "inc/cat_ids.php"); $catName = str_replace("-"," ",$catSlug); $cats .= "<a href=\"index.php?category=$catSlug\">".strtoupper($catName)."</a>, "; } $cats = substr($cats,0,-2); As you can see there's get_value_of function that is used to read the category from the file. File is cat_ids.php and looks like this: Quote 1='category-name-1'; 2='category-name-2'; 3='category name-3'; 4='category-name-4'; 5='category-name-5'; etc. I want to improve this in order not to read the file at each step ("for" loop). Means, one can load the file and then generate a list of (links) category compared to the numbers (Ids). So if $category is "1,3,4" I want to get list like this (by reading cat_ids.php): category-name-1, category name-3, category-name-4 With current function I read value for every ID from file in every step. So if article have 10 or more categories script load file 10 or more times. Looking for a solution to do this from a reading file only once. Thanks. I have this array of items in my php file.
$items = array(
array("id" => 100,"categorypath" => "level1/powders", "product" => "Mens powder"),
array("id" => 200,"categorypath" => "level1/oils/sunflower", "product" => "XYZ oil"),
array("id" => 300,"categorypath" => "level1/eatable/vegetables", "product" => "carrot"),
array("id" => 400,"categorypath" => "level1/oils/sunflower", "product" => "ABC oil"),
array("id" => 500,"categorypath" => "level1/eatable/fruits", "product" => "mango"),
array("id" => 600,"categorypath" => "level1/eatable/vegetables", "product" => "spinach"),
array("id" => 700,"categorypath" => "level2/baby items/toys", "product" => "puzzle block"),
array("id" => 800,"categorypath" => "level2/baby items/toys", "product" => "trucks and cars"),
array("id" => 900,"categorypath" => "level2/baby items/clothes", "product" => "shirts"),
array("id" => 1000,"categorypath" => "level1/powders", "product" => "Womens powder"),
array("id" => 1100,"categorypath" => "level1/oils/groundnut", "product" => "GN oil"),
);
Using the above array I am trying to generate a JSON file that will have the following structu
{
"category":[
{
"categoryName":"level1",
"category":[
{
"categoryName":"powders",
"products":[

Not being an expert in php, I have somehow managed to reach thus far in my code, but can not quite arrive at the correct logic. Having trouble with handling associative arrays and objects in php. (Javascripting is much easier I feel) So far I have managed to fix all the errors/warning in my code. Here is my full php code:
$items = array(

array("id" => 300,"categorypath" => "level1/eatable/vegetables", "product" => "carrot"),
array("id" => 400,"categorypath" => "level1/oils/sunflower", "product" => "ABC oil"),
array("id" => 500,"categorypath" => "level1/eatable/fruits", "product" => "mango"),
array("id" => 600,"categorypath" => "level1/eatable/vegetables", "product" => "spinach"),

I have now reached a point where I desperately need help from experts.
I'm trying to set different colors on rows of a table using an array, Problem is I cannot get it to work right, i'm not sure where to place my for loop so that it works right and generates a different color for different row. Code: [Select] $color = array(red,green,blue); while ($row = mysql_fetch_assoc($exec)) { echo '<tr>'; echo '<td>'.$row['brand_name'].'</td>'; echo '<td>'.$row['contact_name'].'</td>'; echo '<td>'.$row['contact_info'].'</td>'; echo '<td>'.$row['email'].'</td>'; echo '<td>'.$row['description'].'</td>'; echo '</tr>'; } I tried putting for loop only for tr, but it didnt work. Code: [Select] for ($i=0;$i<=count($color);$i++) { echo "<tr bgcolor=\"".$color[$i]."\">"; } I cannot put it within the while loop, it'll repeat the rows for all the colors. So where exactly do I place the for loop so that it works right? Been looking to see if anyone has published something like this. I have a number of projects coming up which entail creating input form pages using PHP. Some of these are quite large as to the number of entries, pages etc.. and the worst part is that I know in advance that they most likely will want to change/add to the form after I am done. So rather than coding them physically in the code, I want to define the form elements in an array that I can store in a database/flat file and when the page loads, read from the array to construct the form output. I don't have any issues with dealing with the database or even using arrays, but I have not been able to come up with an array setup that works. Has anyone done this and would care to share the structure they used. Everything that I find on the net is basically sites that want to host the form, but this will be in a non-Internet accessible site so that is not an option. I have a MySQL table with a list of albums and there is a field called "views" with the number of views each album has received. I'm looking to generate an array of all the albums in the table and sort the array by the number of views (descending). I have a list of functions defined in a ContentController.php file. I created a new function called build_albumlist, which I've pasted below. The function "get_ip_log" already exists and works, and I used it as a template to create the "build_albumlist" function: public function build_albumlist(){ return $this->select_raw("SELECT * FROM albums WHERE deleted = '0' ORDER BY views DESC",array(),'all'); } public function get_ip_log(){ return $this->select_raw("SELECT * FROM sessions ORDER BY ID DESC",array(),'all'); } When I use the function, I get this warning: Warning: mysql_real_escape_string() expects parameter 1 to be string, array given inC:\xampp\htdocs\Controllers\DBController.php on line 10 [font=cabin, 'trebuchet ms', helvetica, arial, sans-serif]The "select_raw" function that I used in "build_albumlist" is defined in the DBController.php file, and is defined as below:[/font] private function clean_array($params){ $final=array(); foreach($params as $param){ $final[]=mysql_real_escape_string($param); } return $final; } public function select_raw($query,$params,$type=''){ $query=str_replace("?","'%s'",$query); $final_query= call_user_func_array('sprintf', array_merge((array)$query, $this->clean_array($params))); if($type==''){ $result=mysql_query($final_query) or die(mysql_error()); return mysql_fetch_assoc($result); } elseif($type=='all'){ $result=mysql_query($final_query) or die(mysql_error()); $final=array(); while($row=mysql_fetch_assoc($result)){ $final[]=$row; } return $final; } Does anyone know why the "build_albumlist" function is generating this warning, while the "get_ip_log" is not? Any help would be great, as I am obviously pretty new to this. hi i am trying to make a payroll calculator script that takes employee info, calculates pay, displays submitted info in a table, stores info in an array, and updates the array when new info is submitted. i have most of these accomplished, i am having trouble with the "store into an array, and update the array when new info is submitted" parts of the project. i am still not very fluent in php so there may be easier ways to achieve what i have so far. any pointers would be a great help, this part has got me stumped.

PROBLEM : I am unable to understand what should possibly be the logic & loop used here for creating a MATRIX ALLOCATION MAP as shown above I have tried while, foreach & for but unable determine the perfect combination which would meet the conditions. (Tried all of the above with Nested Loops also) Edited May 1, 2020 by AlphaMikeTags I am having some problems getting a query correct. Basically I have two tables, one with listings and another with categories. In the listings table I have a column called shortdescription. I am trying to pull the shortdescription from the listings table with the query $shortdesc = array_shift(mysql_fetch_row(mysql_query("select shortdescription from links where category = '".$scat->id."' "))); The shortdecription display properly on the pages display the listings, however I am getting the following error on any pages that only display the parent categories Warning: array_shift() [function.array-shift]: The argument should be an array in /home/...path/file.php on line 1462 The listings id numbers begin at 75+ because the initial parent category id ends at 74. The query seems to be searching for listing ids below 75 and spitting out an error because it is not finding them. Any ideas on how to eliminate this error and/or stop the query from looking for non-existant data? How can i save array from inputs, witch is $igraci and it have 5 values, to mysql base, i tryed but in mysql it shows Array. This is form: <form action="dodaj_klan.php" method="post" > <p> <label>Naziv klana:</label> <input name="naziv" type="text" size="20%" /> <label>Web Sajt:</label> <input name="website" type="text" size="20%" /> <label>E-Mail:</label> <input name="email" type="text" size="20%" /> <br /><br /> <label>Igraci klana(5):</label> <input name="lider" type="radio" value="1" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="2" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="3" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="4" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="5" /> <input name="igraci[]" type="text" size="20%" /> <label><i>(obelezi lidera klana)</i></label> <br /><br /> <input class="button" type="submit" name="submit" value="Dodaj" /> </p> </form> Now i wonna save this igraci[] array in mysql, i tried like this but it doesn't work: $igraci = $_POST['igraci']; $query = "INSERT INTO klanovi (naziv, website, email, igraci) VALUES ('{$naziv}', '{$website}', '{$email}', '{$igraci}')"; $result = mysql_query($query, $connection); How can i do this? Thanks.. Using curl_multi, I have loaded up 3 url's and then printed the array. 1) How can I also set a timestamp on output to let me know when each url was run? 2) How can I explode the array to only display the data and timestamp, excluding the text "Array ( =>", "[1] =>", "[2] =>" and " )"? Code <?php function multiRequest($data, $options = array()) { // array of curl handles $curly = array(); // data to be returned $result = array(); // multi handle $mh = curl_multi_init(); // loop through $data and create curl handles // then add them to the multi-handle foreach ($data as $id => $d) { $curly[$id] = curl_init(); $url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d; curl_setopt($curly[$id], CURLOPT_URL, $url); curl_setopt($curly[$id], CURLOPT_HEADER, 0); curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, 1); // post? if (is_array($d)) { if (!empty($d['post'])) { curl_setopt($curly[$id], CURLOPT_POST, 1); curl_setopt($curly[$id], CURLOPT_POSTFIELDS, $d['post']); } } // extra options? if (!empty($options)) { curl_setopt_array($curly[$id], $options); } curl_multi_add_handle($mh, $curly[$id]); } // execute the handles $running = null; do { curl_multi_exec($mh, $running); } while($running > 0); // get content and remove handles foreach($curly as $id => $c) { $result[$id] = curl_multi_getcontent($c); curl_multi_remove_handle($mh, $c); } // all done curl_multi_close($mh); return $result; } $data = array(array(),array()); $data[0]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Pearl+Jam&output=json'; $data[1]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Black+Eyed+Peas&output=json'; $data[2]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Nirvana&output=json'; $r = multiRequest($data); print_r($r); ?> Output Array ( => Pearl Jam [1] => Black Eyed Peas [2] => Nirvana ) Preferred Output 01:00:01 Pearl Jam 01:00:02 Black Eyed Peas 01:00:03 Nirvana So I'm trying to create an Array from a comma separated string containing array{s}. How can I take a string full of comma separated hex values such as : <?php $myStr = ( "00ffff", "00cccc", "009999", "007777", "004444", "001111", "01ffff", "01cccc", "019999" ); ?> & turn it into 3 separated arrays like : <?php $myNewArrs = [ Array1 ( 3 ), Array2 ( 3 ), Array3 ( 3 ), ]; ?> which REALLY looks like :
<?php
$myNewArrs = [
Array ( "00ffff", "00cccc", "009999" ),
Array ( "007777", "004444", "001111" ),
Array ( "01ffff", "01cccc", "019999" ),
];
?>
? Thank you & have a great afternoon!
Edited May 27 by AquariaXI I have mysql select query shown below retrieving data from a database:
$sql = "
SELECT
student, sum( test_score ) as score
FROM
test
INNER JOIN
level
ON
test.level_id = level.level_id
GROUP BY
student"
$result = $mysqli->query($sql, MYSQLI_STORE_RESULT);
if($result)
{
while ($row = $result->fetch_array(MYSQLI_ASSOC))
{
var_dump($row);
}
}
On inspection of the retrieved array with var_dump(), i have these result below:
array (size=2) 'John' => string 'English' (length=2) 'Score' => string '20' (length=3) array (size=2) 'Mary' => string 'Math' (length=3) 'Score' => string '35' (length=3) array (size=2) 'Samuel' => string 'Physics' (length=3) 'Score' => string '5' (length=3)How do I get at and print out the highest score from this set of array values within this context. I tried this echo max($row['count']) but i understandably got this feedback: Warning: max(): When only one parameter is given, it must be an array Thanks. I need a help in the following : I have an admin page from where the admin attaches an gif image.This attached image should be shown to the user as a scrolling image. The code for the scrolling image is done through javascript. So my actual problem is getting the name of the attached gif image to the javascript array which is used for scrolling horizontally. Hello all, I have yet again trouble finding a logical solution to my problem. I'm fetching an array which can hold 1 or more values. The problem is, I want these values to ouput in my json_encode function, but this also needs to happen dynamically depending on the amount of values. I can't explain it further, so here's the code so far: Code: (php) [Select] $files = mysql_fetch_array($get_files); $a = count($files); $i = 1; while ($files) { $variablename = 'fileName' . $i; $$variablename = $files['fileName']; $i++; } $output = array( OTHER VALUES , 'fileName1' => $fileName1, 'fileName2' => $fileName2, 'fileName3' => $fileName3, ............); // How do I add the fileNames dynamically depending on how many there are? This got me thinking, I also need to dynamically GET the values with jQuery. How would I do that, when the above eventually works? Thank you. Hi there, Basic question, but I can't seem to find a page in the PHP docs that answers (though I'm sure such a one exists, I just can't seem to think up the right search terms - anyway) My question is: is there a short-hand way to use a value from an associative array as the key in another associative array? So for example, given this array: $the_array = array(0 => array('name': 'the_name', 'value' : 'the_value'), 1 => etc....); then this kind of foreach loop doesn't work Code: [Select] $new_data = array(); foreach($the_array as $element){ $new_data[$element['name']] = $element['value']; } Obviously I can just save out the values, like $name = $element['name'] --- but I was just wondering if there was a more efficient way to do it? Cheers, PS. I tried encapsulating with {} - i.e. $new_data[{$element['name']}] --- but that also fails. This topic has been moved to PHP Applications. http://www.phpfreaks.com/forums/index.php?topic=344127.0 Currently, I am trying to make my URL shortener script able to track UTM variables from Google Analytics. I also want to provide my own (campaign/keyword/source/etc...) variables. I am trying to sift through $_GET, pick out "approved" key/value pairs and set each key with the condition that UTM variables take higher precedence (I only want to store one value in the database). My code is currently: Code: [Select] //Parse $_GET and only get the key/pairs that we need and store them in global $url_params for use through out the script function set_url_params($allowed=NULL) { // $allowed is arg to add new values in future dev global $url_params; $allowed = array( 'l', // Redirect key (e.g http://example.com?l=a1dFd7) 'utm_campaign', 'campaign', 'utm_source' , 'source', 'utm_medium', 'medium', 'utm_term', 'term', 'keyword', 'kw', ); $approved = array_intersect_key($_GET, array_flip($allowed)); foreach($approved as $key => $value) { strip_tags(urldecode(trim($value))); $url_params[$key] = $value; } //Assign variables to global $url_params variable so other functions can use them. //NOTE: Google Analytics UTM parameters take precedence over script values. $url_params['l'] = isset($approved['l']) ? $approved['l'] : NULL ; $url_params['campaign'] = isset($approved['utm_campaign']) ? $approved['utm_campaign'] : $approved['campaign']; $url_params['source'] = isset($approved['utm_source']) ? $approved['utm_source'] : $approved['source']; $url_params['medium'] = isset($approved['utm_medium']) ? $approved['utm_medium'] : $approved['medium']; $url_params['term'] = isset($approved['utm_term']) ? $approved['utm_term'] : $approved['term']; $url_params['keyword'] = isset($approved['keyword']) ? $approved['keyword'] : $approved['kw']; // Just in case $url_params doesn't have a 'keyword' set, we will use 'term' instead. $url_params['keyword'] = isset($url_params['keyword']) ? $url_params['keyword'] : $url_params['term']; } I basically want to find a cleaner way of doing this without all the isset()'s. I also get NOTICE errors (running in E_ALL) for undefined variables that I would like to unset so I don't get those errors. Any help would be appreciated. Thanks. Hi, I am very new to PHP and apologies if this question has already been answered in another thread.
I am trying to extract the information from one array into another when some search criteria is matched.
Here is an example array ($original):
Array ( [ 1234567 ] => Array ( [name] => john ) [ 3456 ] => Array ( [name] => johnny ) [ 45673 ] => Array ( [name] => james ) [ 987 ] => Array ( [name] => jamie ) [ 5628721 ] => Array ( [name] => Simon ))
So if I searched for the string john, jo, joh then the new array ($filtered) should be as follows:
Array ( [ 1234567 ] => Array ( [name] => john ) [ 3456 ] => Array ( [name] => johnny ))
I was trying to do this using array_search & preg_match but have been struggling.
Any help would be much appreciated!
