Question

Trying to check the string for pattern.

$variable = '[text]';

if (eregi("/(\[(.*?)\])/", $variable)) {}

This code gives error eregi() [function.eregi]: REG_BADRPT

What is the solution for this?

Answer 1

It’s because you’re using a preg style expression in eregi. You don’t need the perl style delimiters.

However, as Mark Byers comments, using preg_match is future proof.

<?php
$variable = '[text]';

if (preg_match("/(\[(.*?)\])/", $variable)) {
    echo 'ok';
}
