func_get_args

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

Description

int 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.
