What are the best practices for finding and editing template files in a PHP-based webshop to insert tracking code?

To insert tracking code into a PHP-based webshop, the best practice is to locate the template files where the code should be inserted. Once the template files are identified, you can edit them to include the tracking code snippet. It is important to make sure that the tracking code is placed in the correct location within the template files to ensure proper functionality.

// Example code snippet to insert tracking code in a PHP template file
<?php
// Open the template file where tracking code needs to be inserted
$template_file = 'path/to/template/file.php';
$template_content = file_get_contents($template_file);

// Insert the tracking code snippet at the desired location in the template file
$tracking_code = "<!-- Tracking code snippet goes here -->";
$template_content = str_replace('</body>', $tracking_code . '</body>', $template_content);

// Save the modified template file with the tracking code inserted
file_put_contents($template_file, $template_content);
?>
