有没有办法在 PHP Twig 中比较字符串而忽略大小写？

Question

I am working with a twig in PHP, and I need to add a way to filter the results. I decided to do this in the templating language by also injecting the filtering keyword. (My data fetches all categories which each contain listings, and I want to filter the listings). According to the twig documentation, there is not such a way, unless I have missed some part of the docs.

If I use something such as:

{% if listing.name == filter %}
    ...
{%  endif %}

My code will not match correctly if the name is "test" and the filter is "Test". I hope to be able to gain this functionality.

Thank you for the help!

To expand on u_mulder's comment, the standard method is to convert both strings to lowercase (so as to avoid any unknown capitalisation in either string) and then run a comparison that checks the type as well as content.

In PHP, this looks a little like this:

<?php

$stringOne = 'AbcdEfg';
$stringTwo = 'Abcdeefg';

if (strtolower($stringOne) === strtolower($stringTwo)) {
    // comparison is true
} else {
    // comparison is false
}

And again, Yash Karanke is correct, read the How To Ask post to better format questions
