WordPress Hooks (Actions and Filters) Search Tool

December 20, 2013 PHP Jesin A 5 Comments

This started out as a PHP regex experiment. I wanted to find the WordPress “action” hooks in a particular theme so that I can add my own action function to it.

So instead of searching through the whole lot of files for do_actions I sat down writing a regular expression to do this. I was very satisfied with the results which made me think about creating a tool to do this.

So here you go a standalone PHP script which seeps through the PHP code of the WordPress core, plugins, themes or anything you specify and gets you a list of actions and filters.

I use the word “standalone” because this isn’t a WordPress plugin or anything which requires WordPress functions. This is a script which uses a regex in preg_match_all() to find all “tag” names in the do_action() and apply_filters() function. This does not even require WordPress, if you want to find the hooks in a plugin just download the plugin, unzip it to a directory readable by this tool.

A quick tutorial on how to check for open ports using PHP. This function fsockopen() is used in the Open Port Check Tool in this blog. You can check whether a certain port is open on a specified IP address or hostname. Before reading take note that most FREE web hosting providers disable fsockopen() function as a security measure so first check whether the function can be used.

PHP random string generation

January 18, 2011 PHP Jesin A Leave a Comment

Generate a random alphanumeric string containing both uppercase and lowercase characters in PHP. The rand() function in PHP generates a random number we’ll be using this function to generate a random alphanumeric string. A variable should be declared containing all the alphabets in English both uppercase and lowercase (A-Z and a-z) and numbers from 0-9. The concept here is to randomly pick a character from the string containing all the characters and assign it to a variable. Each time this process is done the currently randomly selected character is concatenated with the previously generated characters. This should be done as many times the length of the random string required. For this a looping statement can be used.Continue Reading…
