4.getParams ()
function: Get the entire parameter list at once

5.clearParams ()
function: Empty a parameter (pass in a single string), multiple parameters (incoming array), all parameters (no parameter)

Example:

<?php
require_once ' zend/controller/front.php ';    Load Zend_controller_front class
$front = Zend_controller_front::getinstance ();  Get the front-end controller instance
$front->setparam (' name ', ' John ');        Set the front controller parameter
$name = $front->getparam (' name ');        Gets the Set parameter
echo $name;
echo "<p>";
$array = Array (
  ' g_n ' => ' association ', '
  g_c ' => ' 5000 ', ' g_a ' => '
  Beijing ',
  ' g_p ' => ' Lenovo Group '
);
$front->setparams ($array);
$g = $front->getparams ();
foreach ($g as $k => $v) {
  echo $k. " The value is: ". $v;
  echo "<p>";
}
$front->clearparams ();
$last = $front->getparams ();
foreach ($last as $k => $v) {
  echo $k. " The value is: ". $v;
  echo "<p>";
}

The results are:

The value of John name is: John G_n value is: The value of association G_c is: 5000 g_a value is: The
value of
Beijing g_p is
: Lenovo Group

Because the parameter is cleared, there is no data output for the second call.
