I figured since this site is about PHP we will get people linking to php.net to functions. I have added a new BBCode which will make this easier for everyone. The way it works is just like any other bbcode. Remove the underscores from the example below and see how it works! :)

[_function_]str_replace[/_function_]

Or you can just click this button in the editor and it will give you a popup. Then all you do is input the function's name!

This is the actual example here:
str_replace

Feel free to use this thread to test this! Enjoy! :)
