What resources or documentation can be helpful for resolving issues related to links not working on a PHP website, specifically in a social networking context?
Issue: When links are not working on a PHP website, it could be due to incorrect URL formatting or a problem with the server configuration. To resolve this issue, ensure that the links are properly formatted with the correct protocol (http:// or https://) and domain. Additionally, check the server configuration to ensure that URL rewriting rules are correctly set up.
<?php
// Example of a correct link format in PHP
$link = "http://www.example.com";
echo "<a href='$link'>Click here</a>";
?>
