• PHP Replace last occurrence of a String in a String? 14 answers

I need to remove the domain name from the end of a string. I have tried the following code:

    $domainNAME="example.com";
    $result="_xmpp-client._tcp.example.com..example.com"
    $string = $result;
    $string = str_replace(".".$domainNAME, " ", $string);

Here the result is "_xmpp-client._tcp.". But the result should be "_xmpp-client._tcp.example.com.".

I need to remove the domain name only from the end of string, if domain name exists anywhere in the string it should not be removed.How can I change the code for that?

Any help should be appreciated!

You could use preg_replace and specify the end of string marker $:

$string = preg_replace("/" . $domainNAME . "$/", " ", $string);
