Question

Here is an example of how I am using strstr on my localhost on PHP 5.3.10

<?php
$string  = '25_testing';
$test = strstr($string, '_', true); // As of PHP 5.3.0
echo $test; // prints 25
?>

Well, I uploaded my files on my hosting server but they are running off of PHP 5.2 so the function strstr($string, '_', true) does not work. Is there an alternative I can use, to get the same results?

Try this…

First you return the string after “_” (including itself) and then replace it with nothing. Not very nice but it works 😉

<?php
    $string = "25_testing";
    echo str_replace(stristr($string,"_"),"",$string);
?>

or

<?php
    $string = "25_testing";
    echo str_replace(strstr($string,"_"),"",$string);
?>
