Tell me how you get out of the situation when you need to cut out some Cyrillic word, a letter from the text. ( str_replace does not work)
I tried the self-written functions of the mb_str_replace type - none of them gave proper results.

Example:
Suppose we have a line: $calc = "1Ρ‡20ΠΌΠΈΠ½+1Ρ‡50ΠΌΠΈΠ½";
And from it you need to remove the "min."

Or more complex cases, where there is a lot of sparse text (the initial encoding is not known in advance) and something needs to be changed in it.

If the original encoding is not known in advance and, for example, you need to convert the text to a common utf-8 encoding.

 <?php $str = "1Ρ‡20ΠΌΠΈΠ½+1Ρ‡50ΠΌΠΈΠ½"; $charset = mb_detect_encoding($str); $str = iconv($charset, "UTF-8", $str); $str = str_replace("ΠΌΠΈΠ½", "", $str); echo $str; //1Ρ‡20+1Ρ‡50 ?>

  • Yes, I found an error in the difference of encodings, because of this, there was a problem. - Vlad

You do something wrong, the str_replace function works successfully on this case.

 $t = str_replace("ΠΌΠΈΠ½", "", "1час5ΠΌΠΈΠ½"); echo $t; //1час5

PHP documentation on str_replace

mixed str_replace (mixed $ search, mixed $ replace, mixed $ subject [, int & $ count])

If you want to translate a string to another encoding, use the iconv function.

 iconv("UTF-8", "ISO-8859-1", "hello");
