Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in

Question

I need a little help. Because preg_replace is deprecated, I have to convert all my preg_replace to preg_replace_callback...

Answer 1

The callback needs to be a function taking one parameter which is an array of matches. You can pass any kind of callback, including an anonymous function.

$template = preg_replace_callback(
    "#\\[aviable=(.+?)\\](.*?)\\[/aviable\\]#isu",
    function($matches) {
        return $this->check_module($matches[1], $matches[2]);
    },
    $template
);

(PHP >= 5.4.0 required in order to use $this inside the anonymous function)
