PHP - Need Help Changing An Array
Hi,
I've got the follow array: Query: Code: [Select] SELECT concat(monthname(gl_date),", ",year(gl_date)) as "monthYear", concat(DATE_FORMAT(gl_date,"%d-%m-%Y"),", ",gl_venue) as "dateVenue", DATE_FORMAT(gl_date,"%d-%m-%Y")as "date", gl_venue as "venue", gl_city as "city", gl_postcode as "postcode", gl_text as "description", concat(DAYOFMONTH(gl_date), MONTHNAME(gl_date),".png") AS "imageName" FROM tg_gig_list where gl_date >= curdate() and gl_publish = 1 order by gl_date Array: Code: [Select] $array = array(); $array['gigs'] = array(); while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { $array['gigs'][] =$row; } $output = json_encode($array); This returns JSON like this: - Code: [Select] { "gigs": [ { "monthYear": "May, 2011", "dateVenue": "14-05-2011, Queen Victoria hall", "date": "14-05-2011", "venue": "Queen Victoria hall", "city": "Oundle", "postcode": "PE8 4EJ", "description": "", "imageName": "14May.png" }, { "monthYear": "May, 2011", "dateVenue": "19-05-2011, O'Neill's", "date": "19-05-2011", "venue": "O'Neill's", "city": "Peterborough", "postcode": "PE1 1SQ", "description": "This one is another outing for Jason and Darren's acoustic duo, the pair will be playing a selection of their favourite songs as well as some tunes from the guards set.<br \/>\r\n<br \/>\r\n19:00 to 21:00", "imageName": "19May.png" }, {.......next record I'd like the data to be arranged by the 'monthYear' field....something like this... Code: [Select] { "gigs": [ "monthYear": "May, 2011" { "monthYear": "May, 2011", "dateVenue": "14-05-2011, Queen Victoria hall", "date": "14-05-2011", "venue": "Queen Victoria hall", "city": "Oundle", "postcode": "PE8 4EJ", "description": "", "imageName": "14May.png" }, {......all gigs for 'May, 2011' } "monthYear": "June, 2011" {....records for 'June, 2011' so 'gigs'=>'monthYear'=>'other records' I've tried all sorts of combinations of putting the '$row['monthYear']' field in different places in the array, but I seem to loose data by doing so for some reason. any input greatly appreciated. Darren Similar TutorialsI have a sequential multidimensional array with many outer rows where all the inner arrays have the same number of elements as another sequential array which represents metadata of the first array's inner arrrays. $keys: ["time","system1_typeA","system2_typeA","system1_typeB","system3_typeC","system2_typeB","system1_typeC"] $arrayValues: [ ["2020-06-27 07:40:06",2.16,9.25,9.44,7.76,5.43,1.12], ["2020-06-27 07:40:23",2.66,8.93,4.31,6.59,8.44,3.42], ["2020-06-27 07:41:24",8.71,2.78,8.92,6.58,3.65,4.38], ["2020-06-27 07:41:58",1.86,6.36,2.65,3.99,7.25,3.32], ["2020-06-27 07:42:33",8.71,3.66,8.82,8.54,8.22,4.51] ]
{
"time": ["2020-06-27 07:40:06", "2020-06-27 07:40:23", "2020-06-27 07:41:24", "2020-06-27 07:41:58", "2020-06-27 07:42:33"],
"system1": {
"typeA": [2.16, 2.66, 8.71, 1.86, 8.71],
"typeB": [9.44, 4.31, 8.92, 2.65, 8.82],
"typeC": [1.12, 3.42, 4.38, 3.32, 4.51]
},
"system2": {
"typeA": [9.25, 8.93, 2.78, 6.36, 3.66],
"typeB": [5.43, 8.44, 3.65, 7.25, 8.22]
},
"system3": {
"typeC": [7.76, 6.59, 6.58, 3.99, 8.54]
}
}
Is there much faster way to do so than the following? I would like to use a built in function like array_combine() if possible, but grouping by system and type creates an issue.
function transform(array $keys, array $arrayValues):array {
$map=[];
foreach ($keys as $key) {
$map[] = explode('_',$key);
}
$count=count($keys);
$newValues=[];
foreach ($arrayValues as $i=>$arrayValue) {
$newValues['time'][]=$arrayValue[0];
for ($i = 1; $i < $count; $i++) {
$newValues[$map[$i][0]][$map[$i][1]][]=$arrayValue[$i];
}
}
return $newValues;
}
Hi Just learning PHP and I'm struggling with a very simple problem. I'm playing around with arrays as i figure they're one of the most important things to know inside out but I can't work out how to change the value of an array element via a loop. I can obviously do it if I just directly write $cars[2] = "test" but not having any luck with the loop. I've tried using "foreach" and passing a new value to the $value variable but when i do a print_r the values in the array are unchanged. Code: [Select] $cars[0]="Saab"; $cars[1]="Volvo"; $cars[2]="BMW"; $cars[3]="Toyota"; foreach ($cars as $key => $value) { $value = "TEST"; echo $key . " " . $value . "<br />"; } print_r($cars) I then tried using a for loop Code: [Select] for ($i=0; $i <= count($cars); $i++) { echo $cars[$i]; $cars[$i] = "2"; } But this code just threw up a fatal error as follows: "Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 16 bytes) in /home/zzzzzzzz/public_html/php_testing/arrays.php on line 27" So would someone be kind enough to explain where i'm going wrong and why i get the fatal error on the second for loop. Thanks Drongo Hi I have an array which looks like this when i do a print_r(): Array ( => Array ( [path] => 1 [order] => 2 ) [1] => Array ( [path] => 2 [order] => 1 ) [2] => Array ( [path] => 3 [order] => 2 ) ) In this instance, I want to change the values of the order key. So I do something like this so that the last array has a path of 3 and an order of 1, and the others have orders of 2 foreach ($old_images as $old_image){ if($old_image['path']==3){ $old_image['order']="1"; } else{ $old_image['order']="2"; } } When i step through, i see that the order is changed, but when i do a print_r(), i get the same result. So even though im resetting the order value of the inside arrays, the multidimensional array does not change.... any ideas? Ok I am testing foreach in an array as my practice. I wonder how can I assign values in the key of the array.. Here's the code Code: [Select] <?php $username = me_mysql_prep(trim($_POST['username'])); $first_name = me_mysql_prep(trim($_POST['first_name'])); $last_name = me_mysql_prep($_POST['last_name']); $email = me_mysql_prep($_POST['email']); $position = me_mysql_prep($_POST['Position']); $password = me_mysql_prep($_POST['password']); $hashed_password = sha1($password); $required_fields = array($username,$first_name,$last_name, $email, $position, $password); foreach($required as $key => $value) { if($value == "") { echo $key . " Cannot be empty<br>"; } } ?> So the result would be like this... IF username, first name and last name are EMPTY it will echo: Quote username cannot be empty first name cannot be empty last name cannot be empty Anyone? I was trying to show different hex codes as background in a loop for each section of a list. Here's what I done Code: [Select] $rgb; $rgb["c1"] = "ff4c54"; $rgb["c2"] = "ff764c"; $rgb["c3"] = "ffde4c"; $rgb["c3"] = "c7f25f"; $rgb["c4"] = "33c9f7"; $i=0; $pargs = array( 'numberposts' => 10,'orderby'=> 'comment_count', ); $myposts = get_posts( $pargs );$max_count=0; <ul> foreach( $myposts as $post ) : setup_postdata($post); <li style="width:300px;background-color:#<?php foreach($rgb as $color => $hex) { echo $hex[i]; $i++; } ?>"> <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a> - </li> <?php endforeach; ?> </ul> Ending up with just the white background.. and no change in the background colors.

(Tried all of the above with Nested Loops also) Edited May 1, 2020 by AlphaMikeTags 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. 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 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.. 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. 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!

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. 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. Hi, I am changing my ISP and need to import my databases.
Do I I have to create a new datarbase or can I change my database name to import?
