Explode string php
preg_split(), and its PREG_SPLIT_NO_EMPTY option, should do just the trick, here.
And great advantage : it'll skip empty parts even in the middle of the string -- and not just at the beginning or end of it.
The following portion of code :
$string = "|1|2|3|4|";$parts = preg_split('/\|/', $string, -1, PREG_SPLIT_NO_EMPTY);var_dump($parts);
Will give you this resulting array :
array 0 => string '1' (length=1) 1 => string '2' (length=1) 2 => string '3' (length=1) 3 => string '4' (length=1)
take a substring first, then explode.http://codepad.org/4CLZqkle
<?php$string = "|1|2|3|4|";$string = substr($string,1,-1);$array = explode("|", $string); foreach ($array as $part) { echo $part."-";}echo PHP_EOL ;/* or use implode to join */echo implode("-",$array);?>
