jQuery.ajax({

product_id: product_id

add_action( 'wp_ajax_product_remove', 'product_remove' );

function product_remove() {
global $wpdb, $woocommerce;
session_start();
foreach ($woocommerce->cart->get_cart() as $cart_item_key => $cart_item){
if($cart_item['product_id'] == $_POST['product_id'] ){
// Remove product in the cart using cart_item_key.
$woocommerce->cart->get_remove_url($cart_item_key);
}
}
print_r($woocommerce->cart->get_cart());
//echo json_encode(array('status' => 0));
exit();
}

Answer 1

you could use the WC_Cart set_quantity method
And do as this in your php:
$cart = WC()->instance()->cart;
$id = $_POST['product_id'];
$cart_id = $cart->generate_cart_id($id);
$cart_item_id = $cart->find_product_in_cart($cart_id);
if($cart_item_id){
$cart->set_quantity($cart_item_id,0);
}

Answer 2

use this :
$cart = $woocommerce->cart;
foreach ($woocommerce->cart->get_cart() as $cart_item_key => $cart_item){
if($cart_item['product_id'] == $_POST['product_id'] ){
// Remove product in the cart using cart_item_key.
$cart->remove_cart_item($cart_item_key);
}
}

Answer 3

Try this one :
foreach ( $woocommerce->cart->cart_contents as $cart_item_key => $cart_item ) {
if($cart_item['product_id'] == $product_id){
unset($cartdetails->cart_contents[$cart_item_key]);
}
}
