If you want to pass the parameters on intact to another function, use func_get_args and call_user_func_array (careful - this one is only available in recent PHP versions).  For example:



<?php

/* Print an HTML tag.  This accepts a variable number of arguments:

   the first should be the name of the tag, followed by pairs of

   arguments that describe keys and values.  The values are printed

   with surrounding double quote characters.  */

function printTag() {

  $numArgs = func_num_args();

  if ($numArgs < 1) die("printTag given no arguments");

  

  echo "<" . func_get_arg(0);

  for ($i = 1; $i < $numArgs; $i+=2) {

    echo " " . func_get_arg($i);

    if ($i+1 < $numArgs)

      echo "=\"" . func_get_arg($i+1) . "\"";

  }

  echo ">";

  

}



/* Print an HTML tag with a newline on the end */

function printTagNL() {

  $args = func_get_args();

  call_user_func_array("printTag", $args);

  echo "\n";

}



printTagNL("input", "type", "hidden", "name", "SORTORDER", "value", $columnNo);

?>
