(PHP 4 >= 4.0.5, PHP 5)
preg_replace_callback -- Perform a regular expression search and replace using a callbackThe behavior of this function is almost identical to preg_replace(), except for the fact that instead of replacement parameter, one should specify a callback that will be called and passed an array of matched elements in the subject string. The callback should return the replacement string.
You'll often need the callback function for a preg_replace_callback() in just one place. In this case you can use create_function() to declare an anonymous function as callback within the call to preg_replace_callback(). By doing it this way you have all information for the call in one place and do not clutter the function namespace with a callback functions name not used anywhere else.
Example 2. preg_replace_callback() and create_function()

Note: count parameter is available since PHP 5.1.0.
