php fragment

Code
<?php
 
foreach ( $_GET as $key => $value )
{
  echo "$key : $value <br>";
}
 
?>

Same code works equally for $_POST, depending on the method of HTML form. e.g.

Code
<form action="" method="get">
 
<input name="username" type="text" />
<input name="password" type="text" />
<input type="submit"/>
 
</form>

Just iterate across the POST and GET globals

Code
echo "Post data:
";
foreach($_POST as $key=>$value)
  echo "$key:$value
";
echo "Get data:
";
foreach($_GET as $key=>$value)
  echo "$key:$value";

use $_REQUEST

Code
<?php
 
foreach ( $_REQUEST as $key => $value )
{
  echo "$key : $value <br>";
}
 
?>

Code
<?php
echo "Post data: ";
foreach ($_GET as $key => $value)
{
print_r($key , $value);
}
?>

Code
<?php
echo '<pre>';
print_r($_REQUEST);
echo '</pre>';
