get_defined_functions

get_defined_functions

(PHP 4 >= 4.0.4, PHP 5)

get_defined_functionsReturns an array of all defined functions

说明

array get_defined_functions ( void )

Gets an array of all defined functions.

返回值

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"] (see example below).

范例

Example #1 get_defined_functions() example

<?php
function myrow($id$data)
{
    return 
"<tr><th>$id</th><td>$data</td></tr> ";
}

$arr get_defined_functions();

print_r($arr);
?>

以上例程的输出类似于:

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] => myrow
        )

)
