Not the best practice, try HelloWorld_
Better code (Untested)

PHP код:

<?php
 $sName = "SomeName_YouWantCheck"
 $aName = explode('_', $sName);
 if(count($aName) < 2 || strlen($aName[0]) < 1 || strlen($aName[1]) < 1)
 {
    echo 'You not enter RP name';
 }
else 
{
   echo 'You entered RP name';
}
?>
