Question

I am in need of a PHP-program which will take all values from a HTML-link (with GET), regardless of how much one changes things in the address-bar, and then prints it out on the page. The code I have now is this:

HTML:

<a href="test.php?a=value1&amp;b=value2& amp;c=value3">Link</a>

PHP:

<?php 

Echo "Value1: "; Echo $_GET["a"]; Echo "\n";
Echo "Value2: "; Echo $_GET["b"]; Echo "\n";
Echo "Value3: "; Echo $_GET ["c"];

?>

It works as intended for just these values, but it cannot cope with, for example, another variable being added in the address bar. I need some kind of PHP-function which can look for all kinds of variables through the GET-function.

Any help is appreciated!

Use a loop (modify as needed):

foreach ($_GET as $num => $value)
{
    echo 'Value ' . $num . ': ' . htmlentities($value). "<br>" . PHP_EOL;
}
