[SOLVED] This should be easy! But please help

[jubbs]

Hi all,

Sorry to resort to posting yet another "help me" topic, but im really stuck.

This should be so easy, im sure you'll be able to get it *just like that*.

 

eg,

$a = "20070524;apple";
$b = "20070524;banana";
$c = "20070524;carrot";
$d = "20070527;dog";
$e = "20070708;elephant";

 

I am trying to sort the dates from the text, so that similar dates become formatted into a string like:

20070524;apple,banana,carrot

20070527;dog

20070708;elephant

 

Can you please post some code to do this? Whether using an array or string variables, I dont mind. As long as it works, I can get an idea and adapt it to my code.

 

Thanks in advance.

try

<?php
$a = "20070524;apple";
$b = "20070524;banana";
$c = "20070524;carrot";
$d = "20070527;dog";
$e = "20070708;elephant";
$set = array($a, $b, $c, $d, $e);
$out = array();
foreach ($set as $v) {
$a = explode(';', $v);
$out[$a[0]][] = $a[1];
}
foreach ($out as $k => $v) {
$out[$k] = $k.';'.implode(',',$v);
}
foreach ($out as $v) echo $v, "<br />\n";
?>
