How to compress a sitemap with php?

To compress a sitemap with PHP, you can use the built-in Gzip compression functions. Here's an example of how you can compress a sitemap XML file:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15

<?php
// Path to the sitemap XML file
$sitemapFile = 'sitemap.xml';

// Content type header for XML
header('Content-type: application/xml');

// Content encoding header for compressed XML
header('Content-Encoding: gzip');

// Output the compressed XML
ob_start('ob_gzhandler');
readfile($sitemapFile);
ob_end_flush();
?>

Save this code in a PHP file (e.g., compress_sitemap.php), and make sure the sitemap.xml file is in the same directory. When you access this PHP file in a browser, it will compress and display the sitemap XML.

Note that the ob_start('ob_gzhandler') function enables gzip compression for the output, and readfile reads and outputs the contents of the sitemap file. Finally, ob_end_flush() sends the compressed output to the browser.

Make sure the PHP script has the necessary permission to read the sitemap file and to execute the compression functions.

Note: This method only compresses the output of the sitemap XML file when it is accessed through the PHP script. The actual sitemap.xml file on the server remains uncompressed.
