Hook – PHP

Hi Team,

I would like to execute the PHP code below on the WooCommerce product and category pages and exclude this PHP code from the shopping cart.

When performing this php within the hook, the site crashes. Can you maybe advice, please?

Settings:
Hook: woocommere_before_main_content
Location: Products & Product Category
Exclude: page: cart
Php:

<?php
function codeAstrology_remove_wc_currency_symbols( $currency_symbol, $currency ) {
$currency_symbol = ”;
return $currency_symbol;
}
add_filter(‘woocommerce_currency_symbol’, ‘codeAstrology_remove_wc_currency_symbols’, 10, 2);
