You may be interested in mapping the exploded array with trim to avoid a situation like this:

print_r(eexplode(":","evan:walsh: :"));

Some thoughts:

function eexplode($separator,$string){
	$array = array_map('trim',explode($separator,$string));
	foreach($array as $key => $val){
		if($val == "") unset($array[$key]);
	}
	return array_values($array); // resets keys
}

print_r(eexplode(":",": : evan:walsh: :"));

You could also do something like this, but it all depends on if you want to maintain breaks, spaces, tabs, etc ...


function eexplode($separator,$string) {
	return preg_split("/\s*${separator}\s*/",$string,-1,PREG_SPLIT_NO_EMPTY);
}
print_r(eexplode(':',"evan:\nwalsh:\n:\t:\x20:"));

```print_r(array_values(array_filter(explode(":","evan:walsh:"))));```
