Can a script change strings in PHP?

I am on a site where I am looking for replacing 2 strings with each other.

I have 2 strings called Cart and Bag. I want to change where it is Cart, it’ll be replaced with Bag and where it is Bag, it’ll be replaced with Cart.

I have used the below PHP code to change strings:

add_filter( 'gettext', function ( $strings ) {
    $text = array(
        'Bag' => 'Cart',
        'Cart' => 'Bag',
    );
    $strings = str_ireplace( array_keys( $text ), $text, $strings );
    return $strings;
}, 20 );

Which as a result shows al the Cart and Bag strings as Bag.

Can anyone please guide me what correction can be done here?

Or any script that can help?

TIA.

    Let’s take an example of $strings.

    Bag Cart Cart Bag

    str_ireplace searches the gives needles one by one and replaces them with the respective value from the replacements array (passed as the 2nd parameter) .

    So, in this process, the string becomes,

    1 --> Cart Cart Cart Cart
2 --> Bag  Bag  Bag  Bag

    Although there are multiple ways to solve this issue, I would prefer the below approach.

    • Explode the string based on space.
    • Use array_map to map each value from the exploded array with regards to value from $text.
    • Implode the array back to the string.

    Snippet:

    <?php

$strings = implode(" ", array_map(fn($v) => $text[$v] ?? $v, explode(" ", $strings)));

    Split the string into an array then replace cart with bag and vice-versa, and join the array again.

    const str = "This is a cart and bag, cart is cart and bag is bag"
let arr = str.split(" ");
let r = arr.map((s) => s.includes('cart') ? s.replace('cart', 'bag') : s.includes('bag') ? s.replace('bag', 'cart') : s)

let ans = r.join(" ")
console.log(ans)
