I am sure everyone has their own version for exploding with multiple strings. Here is mine. Please
let me know if there are any problems. Thanks.
$subject = "This is a test me!ssage: Here is me message yet another finished";
$separators = array(',',' ','!');
$out = array();
class strFunctions {
/**
* @public
*
* @brief Explode a string by multiple separators at once
*
* @param $_subject string Subject to explode
*
* @param $_separators array Array of strings to separate the subject by
*
* @param $_out array Array to populate the results with
*
* @return boolean TRUE if everything was successful, FALSE otherwise
*/
function explode($_subject, $_separators, &$_out) {
if(!is_string($_subject) || !is_array($_separators) ||
!is_array($_out)) {
return false;
}
if(empty($_separators)) {
// One could replace this part with a call back function
// to be applied to each separated string
// {{{ Start call back function (a.k.a normalizer strategy)
$data = strtolower(trim($_subject));
if($data !== '') {
if(isset($_out[$data])) {
$_out[$data] += 1;
} else {
$_out[$data] = 1;
}
}
// End call back function }}}
return true;
}
// Get the current separator
list($key,$currentSeparator) = each($_separators);
if(!is_string($currentSeparator)) {
return false;
}
// Remove the current separator from the list
unset($_separators[$key]);
// Split the input by the current separator
$explodedArray = explode($currentSeparator,$_subject);
// Call the explode function for each string with the remaining
// separators
foreach($explodedArray as $string) {
if($this->explode($string,$_separators,$_out) === false) {
return false;
}
}
return true;
}
}

$strFunctions =& new strFunctions();
var_dump($strFunctions->explode($subject,$separators,$out));
var_dump($out);
