PHP - Ordering An Array By Another Array?
Hi guys,
I'm trying to modify a Joomla listings directory component to have a sorting capability on category pages that list listings. A bit like eBay, price high to low etc. The basic code that outputs each listing is as follows... foreach ($this->links AS $link) { $fields = $this->fields[$link->link_id]; include $this->loadTemplate('sub_listingSummary.tpl.php'); } I have so far been able to get the contents of an extra field into an array within this foreach loop like this: $sleeps_array = array(); foreach ($this->links AS $link) { $fields = $this->fields[$link->link_id]; $sleeps = $fields->getFieldById(51); if(!is_null($sleeps) && $sleeps->hasValue()){ $sleeps = $sleeps->getOutput(1); $sleeps_array[] = $sleeps; } include $this->loadTemplate('sub_listingSummary.tpl.php'); } sort($sleeps_array); foreach ($sleeps_array as $key => $val) { echo "sleeps_array[" . $key . "] = " . $val . "\n"; } I've got this far but simply adding the include file to the new loop for "sleeps" does not work. I think I need to some how link the 2 arrays so that I can sort listings by the custom field... Can anyone point me in the correct direction? Thanks! RJP1 Similar TutorialsHi I have an array which pull data from a DB (which I didn't create nor can modify) I need to be able to export it to an excel sheet with the data in a specified order. how do I do this? eg run sql queries and end up with array which would be - a [1] - b [2] - c [3] - d [4] - e how would I be able to specify the order eg d , a, c, e, b. to match it up with the column headers on the excel sheet? To make it more of a challenge, I can't amend the column headers either. I can only manipulate the array. I will be pulling multiple arrays out and not all have all the value is them!!! Deep Deep Joy!!! 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? 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 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.

Thanks.. 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. 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!
Edited May 27 by AquariaXI This topic has been moved to PHP Applications. http://www.phpfreaks.com/forums/index.php?topic=344127.0 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. 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, 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!
I need to some how pull comma separated images $data[23] from this $data array and then put them into there own array so I can insert them into separate rows in a database. This is the provided array: $data[0] => VIN $data[1] => StockNumber ...(all the other number here) $data[23] => Image_URLs (comma seperated) $data[24] => Equipment // I need something like this (obviously doesn't work?!@#) $delimiter = ","; $img = explode($delimiter, $data[23]); foreach($img as $pic){ $sqlPic = "insert into class_prodimages (pid image rank) values('".$LastId['id']."', '$pic', '".rand(1,20)."')"; } Any help here? Hi, A piece of software I'm using an array is made that looks like the following: Code: [Select] [["Select","Vehicle",0.142933,[0.15,0.4,0.05,0.01]]] How would I be best parsing it so: Square brackets currently showing an array becomes an array within PHP Text strings surrounded by "quotations" lose the quotation mark when stored in the PHP array Numbers remain as values in the PHP array The arrays can become quite large, so which would be the best way to go about it? Regards, Jason I have a for loop which extracts info from a MySQL table, chooses something then needs to push each bit into an array: for($i = 0 ; $i < $query_report_rows ; ++$i) { $row= mysql_fetch_row($query_names); if($row[6] == 0) { $sName = $row[1]; } elseif($row[6] == 1) { $sName = $row[2]; } $name = "$row[0], $sName"; $print = nl2br($row[7]); } What i need is a multidimensional array to hold $name and $print: $name_print = array( array('name'=>$name 'print'=>$print ) ) How do i array push into such an array from the above for loop? (multi-dimensional array are a very weak point at the moment, so any pointers here would be very much appreciated) I have an array $array_1 Code: [Select] ARRAY( [0] => info 1 [1] => info 2 [2] => info 3 ) and I have another array $array_2 Code: [Select] ARRAY( [0] =>thank you and welcome to what ever [1] =>the info you added * thanks for entering your info ) I want to loop though the first array and place the values into the [1] of the second array. But the tricky thing is I want it to insert were the * is. Code: [Select] foreach ($array_1 as $key => $val) { //not sure about this insert into ($array_2[1],after *, $val); } any help would be awesome. I have the following array structu Code: [Select] [0] => Array ( [id] => Array ( [$t] => http://www.google.com/mate/ ) [updated] => Array ( [$t] => 2011-08-31T11:43:05.942Z ) [category] => Array ( [0] => Array ( [scheme] => http://schemas.google.com/g/ [term] => http://schemas.google.com/contact/ ) ) [title] => Array ( [type] => text [$t] => Name ) [link] => Array ( [0] => Array ( [rel] => http://schemas.google.com/contacts/2008/rel#edit-photo [type] => image/* [href] => https://www.google.com/mate/feeds/photos/media/ ) [1] => Array ( [rel] => self [type] => application/atom+xml [href] => https://www.google.com/mate/feeds/contacts ) [2] => Array ( [rel] => edit [type] => application/atom+xml [href] => https://www.google.com/mate/feeds/ ) ) [gd$email] => Array ( [0] => Array ( [rel] => http://schemas.google.com/g/2005#other [address] => email_address@gmail.com [primary] => true ) ) ) I am tried to display name and email address. I am using following method, can anyone tell me is there any better way? Thank u 4u help. NAME $name=( $emp_det[0]['title'][t]); $email =( $emp_det[0]['gdemail'][0][address]); Hello all, I need to make a rotating banner system for a client. They want about 5 banners to rotate with Javascript. However they want the visitor to sort of step through each one on each refresh. So if I have 5 banners and I go to the site, I see banner 1 and then the javascript rotates through each one. When I go back to the site, they want it to start with banner 2 and then the javascript will rotate through each one. Then on and on. Go back and see banner 3, then step through again. I have a nice Javascript image slider I'd like to use. It basically just requires the images in order. Like: <img src="1.jpg"/> <img src="2.jpg"/> <img src="3.jpg"/> <img src="4.jpg"/> <img src="5.jpg"/> I've thought about it and I think the best way to do this would just be using PHP and a cookie. So when the viewer first goes to the site, PHP checks for the cookie. If it exists, it pulls the starting image #. If it doesn't, it starts at 0 and sets the cookie. As for the images part, I figured an associate array would work well. The key would be what the cookie logic is based on, and then the image HTML would be in the array. So you visit the site without a cookie it would be... 0 => <img src="1.jpg"/> 1 => <img src="2.jpg"/> 2 => <img src="3.jpg"/> 3 => <img src="4.jpg"/> 4 => <img src="5.jpg"/> Then when you go back to the site, I need the array to be re-ordered like this: 0 => <img src="2.jpg"/> 1 => <img src="3.jpg"/> 2 => <img src="4.jpg"/> 3 => <img src="5.jpg"/> 4 => <img src="1.jpg"/> What's the best way to go about this array logic? My experience with manipulating data inside arrays is rather limited. Basically I need it to say "Start with key # and then reorder array based on that" Hi, I'm trying to explode an array into a multidimensional array using <br /> tags as splitters but just can't get the syntax right! I can do lines of the array one by one, but not the whole lot at once. I'd really appreciate a quick example of an explode inside an array. $myarray looks something like this with print_r: ( [0] => [1] => some_html<br />some_html<br />some_html<br /> [2] => some_html<br />some_html<br />some_html<br /> [3] => some_html<br />some_html<br />some_html<br /> ) and I want to turn it into this: ( [0] => [1] => [0]some_html [1]some_html [2]some_html [2] => [0]some_html [1]some_html [2]some_html [3] => [0]some_html [1]some_html [2]some_html ) I've tried this $myarray = explode ("<br />", $myarray); but it doesn't work … It doesn't matter too much if there's are a few empty lines in the array from the final <br /> tags. Many thanks, as ever, for any help. |
