What potential issues could arise when integrating the provided PHP code into a website?

One potential issue that could arise when integrating the provided PHP code into a website is that it may not be compatible with the existing codebase, leading to conflicts or errors. To solve this, ensure that the PHP version being used is compatible with the code and that there are no naming conflicts with existing functions or variables. 

<?php
// Ensure compatibility with existing codebase
// Check PHP version and resolve naming conflicts

// Updated PHP code snippet
// Example: Check PHP version
if (version_compare(PHP_VERSION, '7.0.0') < 0) {
    die('PHP version 7.0.0 or higher is required');
}

// Example: Resolve naming conflicts
if (!function_exists('my_custom_function')) {
    function my_custom_function() {
        // Function implementation
    }
}
?>
