note 102673 added to function.explode

An improvement to my previous post, this version will also trim whitespace from the front and end of the string, as well as allow you to specify a delimiter yourself.

<?php

/* Performs explode() on a string with the given delimiter and trims all whitespace for the elements */
function explode_trim($str, $delimiter = ',') {
    if ( is_string($delimiter) ) {
        $str = trim(preg_replace('|\\s*(?:' . preg_quote($delimiter) . ')\\s*|', $delimiter, $str));
        return explode($delimiter, $str);
    }
    return $str;
}

// Test
$str = '    mouse ,cat , dog  ,  human    ';
$array = explode_trim($str);
print_r($array);

?>

This will output:
(
    [0] => mouse
    [1] => cat
    [2] => dog
    [3] => human
)
