override_function — Overrides built-in functions
说明
bool override_function ( string $function_name , string $function_args , string $function_code )
Overrides built-in functions by replacing them in the symbol table.
参数
- 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.
返回值
如果成功则返回 TRUE ，失败则返回 FALSE 。
