How to Retrieve the Complete URL, Including Parameters and Anchor Text?

Determining the Complete URL with Parameters and Anchor

It is often useful to obtain the complete URL used to request the current page, including any parameters appended at the end of the URL (query string) and any anchor text that appears after the "#" symbol. Let's explore how to achieve this in PHP.

PHP's Approach

PHP provides the $_SERVER['REQUEST_URI'] variable to retrieve the portion of the URL that is sent to the server. However, this variable does not include the anchor text (the text after the "#").

JavaScript Solution for Anchor Text

Unfortunately, PHP cannot access the anchor text because it is handled solely by the browser. To retrieve the anchor text, you can use JavaScript's document.location.hash property. This property contains the contents of the anchor, including the "#" symbol.

Comprehensive URL Reconstruction

To construct the complete URL, including both the query string and anchor text, you can concatenate the $_SERVER['REQUEST_URI'] variable with the JavaScript document.location.hash property. This combination will give you the entire URL, regardless of whether the included page is foo.php or bar.php.

Example:

<code class="php">$queryString = $_SERVER['REQUEST_URI'];
$anchorText = "<script>document.location.hash</script>";
$completeUrl = $queryString . $anchorText;</code>

Conclusion:

While PHP cannot directly retrieve anchor text, you can use JavaScript to obtain this information and combine it with the $_SERVER['REQUEST_URI'] variable to get the complete URL, including all parameters and anchor text.
