strtok is an overlooked function for this sort of thing  It is meant to be quite fast    s    233718 This is a string    firstPart   strtok   s          allTheRest   strtok           Empty string like this will force the rest of the string to be returned   NB if there was nothing at all after the     you would get a FALSE value for  allTheRest which  as stated in the documentation  must be tested with      to distinguish from other falsy values

The strpos   finds the offset of the underscore  then substr grabs everything from that index plus 1  onwards    data    123 String        whatIWant   substr  data  strpos  data         1       echo  whatIWant      If you also want to check if the underscore character     exists in your string before trying to get it  you can use the following   if    pos   strpos  data            FALSE          whatIWant   substr  data   pos 1
