Message:

I have a PHP variable named $matches[0] which contains a HTML Code.

So, I want to know if is there a way to remove in PHP any from $matches[0] variable these HTML Tags and/or CSS class:

<sup>...</sup> (HTML Tags) ???

class="navigation-only" (CSS Class) ???

class="noprint wikidata-linkback" (CSS Class) ???

If so, how to do to remove all HTML <sup> and navigation-only and noprint wikidata-linkback CSS Classes ???

Because it will very help me.

My Answer:
You can use the `strip_tags()` function in PHP to remove HTML tags from a string. You can also use `preg_replace()` to remove specific CSS classes from the string.

Here's an example of how you can remove `^{` tags and the specified CSS classes from your `$matches[0]` variable:

php

// Remove ^{tags

$matches[0] = strip_tags($matches[0], '^{');

// Remove class="navigation-only"

$matches[0] = preg_replace('/class="navigation-only"/', '', $matches[0]);

// Remove class="noprint wikidata-linkback"

$matches[0] = preg_replace('/class="noprint wikidata-linkback"/', '', $matches[0]);

// Output the modified string

echo $matches[0];}}

This code will remove all `^{` tags and the specified CSS classes from the `$matches[0]` variable. You can adjust the regular expressions in the `preg_replace()` function to match other CSS classes as needed.}}
