Search .php File for word

[Dysan]

Hi,

 

Using PHP, how do I search through all .php files contained in a folder (set by user) for a word (also set by user)?

 

Upon finding occurrences of the specified word, how do I display the line number and file path it is in?

first I would glob() all the php files:

 

This is just an example (not the real deal):

<?php
$find = '~'.$_POST['searchString'].'~';
foreach(glob($_POST['selectedDirectory'].'/*.php') as $filename){   // * stands for wild card
    $handle = fopen($filename, "r");
    $contents = fread($handle, filesize($filename));
    fclose($handle);
    if(preg_match($find,$contents,$matches)){
        echo 'Found a match: '.$matches[0].' in file: '.$filename;
    }
}
?>
