get_defined_functions
- It returns an array of all defined functions
Syntax:
array get_defined_functions ( void)
This function returns an multidimensional array containing a list of all defined functions, both built-in (internal) and user-defined. The internal functions will be accessible via $arr[”internal”], and the user defined ones using $arr[”user”]
Example:
function sample()
{
return true;
}
$arr = get_defined_functions();
print_r($arr);
The result in $arr is
Array
(
[internal] => Array
(
[0] => zend_version
[1] => func_num_args
[2] => func_get_arg
[3] => func_get_args
[4] => strlen
[5] => strcmp
[6] => strncmp
…
[750] => bcscale
[751] => bccomp
)
[user] => Array
(
[0] => sample
)
)
