SearchCo.de:
List of Most Commonly Used PHP Functions
Mar 16, 2011 @ 13:26:27

In a new post to the SearchCo.de blog Ben Boyter generated a listing of the most commonly used PHP functions/structures based on the contents of several of the major PHP projects from around the web.

One thing that I considered some time ago was working out which are the most common functions in a language and adding this as an additional signal to ranking. I couldn't find anywhere else on the web with this question answered so I took my own approch. The method was to take a collection of large PHP projects, including, Wordpress, Mambo, Sphider, Smarty, Drupal, CodeIgniter, dump all their source code into a single file stripped of comments, and then run some simple regex over this file counting the occurance of each function.

His results show the top five as: array, isset, define, empty and assert. The last five ended up being: filemtime, sha1, array_unshift, get_current_user and strchr.

Brendon's Blog:
10 PHP functions you (probably) never use
Jan 15, 2010 @ 11:27:57

New from his blog Brendon has a list of what he thinks are ten PHP functions you'll never use.

When scripting in PHP, we often restrict ourselves to a limited number of API functions: the common ones, like print(), header(), define(), isset(), htmlspecialchars(), etc. [...] The PHP API actually offers a lot of functionality, some useless and some useful; often seldom used. I have been looking through the available functions and was interested to find some really cool functions that I should have known about.

Here's his list of functions, some of which are more on the "special needs" list than the "never use" list:
