How to search in multiple .php files?

Question

I have around 100 .php files in one directory and I'm looking for one small function, what's the fastest way to search trough all contents of these files?

[edit]

I'm using Windows 7 Ultimate/NuSphere PhpED.

Answer 1

Try this:

<?php
function getFilesWith($folder, $searchFor, $extension = 'php') {

    if($folder) {
        $foundArray = array();
        // GRAB ALL FILENAMES WITH SUPPLIED EXTENSION
        foreach(glob($folder . sprintf("*.%s", $extension)) as $file) {
            $contents = file_get_contents($file);

            if(strpos($contents, $searchFor) !== false) {
                $foundArray[] = $file;
            }
        }

        if(count($foundArray)) {
            return $foundArray;
        } else {
            return false;
        }
    } else {
        return false;
    }
}

$matched_files = getFilesWith('path/to/folder', 'Looking for this');
?>

Use your php editors "find in files" function.

Invaluable.

edit PHPNuSphere totally supports this. you need to learn some google fu brother.

If your editor doesn't have this, you need to switch ASAP. https://stackoverflow.com/search?q=php+editor
