PHP-getPage

Allows you to get multiple parts of the URL. Note: this code doesn't work well on "pretty URLs" such as those used in Laravel.

Options

For all of these options, it is assumed that the URL will be http://www.example.com/folder/index.php?sort=true, unless otherwise stated.

'' - No option

A simple case that will simply return the entire URL with HTTP scheme and all URL parameters.

'a' - Page name, extension, and URL parameters

This will return everything from the name of the page until the end of the URL.

$url = get_page('a');
echo $url; // index.php?sort=true

'b' - Full url, excluding extension onwards

Get the entire URL up to, and including, the file name; excluding everything that comes after the file extension.

$url = get_page('b');
echo $url; // http://www.example.com/index

Combining both, the a and b options, it is possible to just return the name of the file and ignore everything else.
This is useful in the following examples:

<ul id="nav">
    <li class="button <?= get_page('ab') == 'page1' ? 'active' : 'inactive'; ?>"><a href="page1.php">Page 1</a></li>
    <li class="button <?= get_page('ab') == 'page2' ? 'active' : 'inactive'; ?>"><a href="page2.php">Page 2</a></li>
</ul>

In the above example, depending on the current active page, that list item will be given the class of active and any other page will be given the inactive class.

'c' - Entire URL up to, and including the file extension

Self explanatory, I hope! Anyway, here's an example.

$url = get_page('c');
echo $url; // http://www.example.com/index.php

'd' - Return the query string

Again, I hope this is quite obvious in what it does. One thing to note is that it strips the question mark (?) from the start of the string.

$url = get_page('d');
echo $url; // sort=true

'e' - Returns the domain name

Extracts just the domain from the URL.

$url = get_page('e');
echo $url; // example

'f' - Returns the domain with HTTP scheme and Top-Level Domain (TLD)

This is probably easier to describe by just showing the example...

$url = get_page('f');
echo $url; // http://www.example.com

'g' - Full URL, excluding the file name

Similar to b or c, with the exception that this will exclude the file name from the string.

$url = get_page('g');
echo $url; // http://www.example.com/folder
