(PECL apd:0.2-1.0.1)
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。
