Pre-commit hook to detect if any .php files contain dd()

pre-commit

#!/usr/bin/php
<?php

$files = shell_exec('git diff-index --name-only --cached --diff-filter=ACMR HEAD | grep "\.php$"');
$files = explode("\n", trim($files));

$exitCode = 0;

foreach ($files as $file) {
    if (empty($file)) {
        continue;
    }

    $lines = file($file);

    foreach ($lines as $line => $content) {
        if (preg_match('/\bdd\(/', $content)) {
            printf("\033[0;31mdd() found on line %d in %s\033[0m\n", $line + 1, $file);
            $exitCode = 1;
        }
    }
}

exit($exitCode);

Maybe add before:

$lines = file($file);

This:

if (empty($file)) {
    continue;
}

@it-can Thanks. Added that, as well as a check for a whitespace character before dd() to avoid it matching names like add().

Cool idea. It would be better to prefix with a word-break \b instead of a whitespace \s.

You may also want to ignore matches which come after a line comment //
