    I have a reason why I need to do this.... It's a code related... what I want to know if possible is how I can display or list all available variables in the php file I am opening..

    For example this is the content of the a.php file

    <?php
    $a = "wala";
    $my="name.";
    echo "this is something";

    $another = "";


    ?>

    Now I want to list all available variable names at a.php, is there a way to do that...

    display the
    $a , $my, $another with out hard coding it.

    Try this: 

    <?php
$a       = 'wala';
$my      = 'name';
$another = '';

$defined      = get_defined_vars();
$exclude_list = array('GLOBALS', '_ENV', 'HTTP_ENV_VARS', '_POST', 'HTTP_POST_VARS', '_GET', 'HTTP_GET_VARS', '_COOKIE', 'HTTP_COOKIE_VARS', '_SERVER', 'HTTP_SERVER_VARS', '_FILES', 'HTTP_POST_FILES', '_REQUEST');

foreach ($exclude_list as $exclude) {
	unset($defined[$exclude]);
}

echo "<pre>";
print_r($defined);
echo "</pre>";
?>
    PHP:
