can you please help me removing all numbers between brackets ex. [4] from that string

using regular expressions Regex ?

Thanks

Just do a preg replace on /\[\d\]/ and replace it with ''

$s = preg_replace( '#\[\d+\]#', '', $context );

I believe that will kill multiple occurrences.

Since the question asks to remove numbers between the brackets and not the brackets themselves, I think this would be what he is looking for:

$string = preg_replace('/(?<=\[)\d+(?=\])/', '', $string);
