override_function — Overrides built-in functions
Leírás
bool override_function
( string $function_name
, string $function_args
, string $function_code
)
Overrides built-in functions by replacing them in the symbol table.
Paraméterek
- 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.
