override_function

(PECL apd:0.2-1.0.1)

override_function — Overrides built-in functions

Description

bool override_function ( string $function_name , string $function_args , string $function_code )

Overrides built-in functions by replacing them in the symbol table.

Parameters

function_name

The function to override.

function_args

The function arguments, as a coma separated string.

Usually you will want to pass this parameter, as well as the function_code parameter, as a single quote delimited string. The reason for using single quoted strings, is to protect the variable names from parsing, otherwise, if you use double quotes there will be a need to escape the variable names, e.g. \$your_var.

function_code

The new code for the function.

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example #1 override_function() example

?>
