func_get_args

(PHP 4 )

func_get_args --  Returns an array comprising a function's argument list

Description

array func_get_args ( void )

Returns an array in which each element is the corresponding member of the current user-defined function's argument list. func_get_args() will generate a warning if called from outside of a function definition.

<?php
function foo() {
    $numargs = func_num_args();
    echo "Number of arguments: $numargs<br>\n";
    if ($numargs >= 2) {
    echo "Second argument is: " . func_get_arg (1) . "<br>\n";
    }
    $arg_list = func_get_args();
    for ($i = 0; $i < $numargs; $i++) {
    echo "Argument $i is: " . $arg_list[$i] . "<br>\n";
    }
} 

foo (1, 2, 3);
 ?>

func_get_args() may be used in conjunction with func_num_args() and func_get_arg() to allow user-defined functions to accept variable-length argument lists.

Note: This function was added in PHP 4.
