How can I change the product tab headings in WooCommerce using PHP?

To change the product tab headings in WooCommerce using PHP, you can use the woocommerce_product_tabs filter. This filter allows you to modify the array of tabs before they are displayed on the product page. Here's how you can do it:

1. Accessing the Theme's `functions.php` File:

- The most common place to add this code is in your theme's `functions.php` file. If you're using a child theme (which is highly recommended), add it to the child theme's `functions.php` file. This ensures your changes won't be overwritten when the parent theme is updated.

2. Using the `woocommerce_product_tabs` Filter:

- The woocommerce_product_tabs filter is used to modify the tabs. You'll need to create a function that takes the existing tabs array as an argument and returns the modified array.

3. Example Code to Change Tab Headings:

function custom_rename_product_tabs( $tabs ) {
  if ( isset( $tabs['description'] ) ) {
    $tabs['description']['title'] = 'Product Details';
  }
  if ( isset( $tabs['additional_information'] ) ) {
    $tabs['additional_information']['title'] = 'Specifications';
  }
  if ( isset( $tabs['reviews'] ) ) {
    $tabs['reviews']['title'] = 'Customer Reviews';
  }
  return $tabs;
}
add_filter( 'woocommerce_product_tabs', 'custom_rename_product_tabs', 98 );

4. Explanation of the Code:

- The custom_rename_product_tabs function takes the $tabs array as input.

- It checks if specific tabs (e.g., 'description', 'additional_information', 'reviews') exist using isset().

- If a tab exists, it modifies the title key within that tab's array to the new heading you want.

- Finally, it returns the modified $tabs array.

- The add_filter() function hooks your custom function into the woocommerce_product_tabs filter with a priority of 98 (lower numbers run earlier).

5. Customizing Tab Headings:

- You can change the tab keys ('description', 'additional_information', 'reviews') and the new titles to match your specific needs.

6. Important Considerations:

- Always use a child theme to avoid losing your changes during theme updates.

- Test your changes thoroughly to ensure they work as expected.

- If you have custom tabs added by plugins, you may need to adjust the code to target those specific tab keys.

By using this method, you can easily customize the product tab headings in WooCommerce to better suit your store's needs and branding.
