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.
