I tried this code:
_______________________________________________________

$correctname = preg_replace("/[^a-zA-Z]/", "", $userid);
$correctname2 = preg_replace('[xxx]', "", $correctname);

echo $correctname2 ;

result showing "username"
_______________________________________________________

But i need the result = "username23",

i am trying to remove only "xxx-" from $userid

Please help.

 

As long as its xxx- this is all you need.

$userid = "xxx-username23";

$correctname = preg_replace('#xxx-#', '', $userid); //replaces xxx- with nothing

echo $correctname;

//result showing "username23"

PHP:

 

EDIT:

A second too late...

$foo = preg_replace('/^x{3}-/', '', $userid);

PHP:

 

trying, thank you guys

 

Or as long as the the username is separated with a -

This will do:

$userid = "12Ab-username23";

$correctname = preg_replace('#(.*-)#', '', $userid); //replaces xxx- with nothing

echo $correctname;

PHP:

 

If that's the only dash that can be in the user name you have lots of options:

list($dummy, $correctname) = explode('-', $userid);
echo $correctname;

PHP:

if the prefix you want to remove is always three chars long, just chop the string off:

$correctname = substr($userid, 4);
echo $correctname;
