override_function
(PECL apd >= 0.2)
override_function — Overrides built-in functions
Description
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 comma 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.
