Search for a certain function in all helper files?

[eluser]Nummero2[/eluser]
Yes thats the point. I´m not getting through the whole meaning of the preg_match function

-Namely where do I then define the function I am searching for? I mean where do I define that it should search the helper files for the _helper_test function if present?

-what is the variable $line for?

Heres my code now but it only shows a one line string like
string(74) "E:/xampp/htdocs/intranet/system/application/helpers/one_helper.php"

Code:

$helpers = glob(APPPATH.'helpers/*_helper.php');

$i=0;
foreach ($helpers as $line) {


preg_match('/^function (.+?)\(/',$line);
$i++;
}


echo var_dump( $line );


Sorry if the whole topic in itself is not reasonable but at the moment I´m just playing around with different ideas/methods.
