$bob = "00074-5"; if i want to get rid of the -5 bit at the end, can i rtrim() it or do i HAVE to explode() it? |

| perhaps none of both ;-) substr($bob,0,-2); will do it faster |

| the trouble is $bob could be 00074-5 or 00074-56 and everything after the - has to go. stupid $bob! | |||

| no problem. strrpos() is your friend ;-) $a=strrpos($bob,'-'); if ($a!==FALSE) $bob=substr($bob,0,$a); // et voila if you're not cautious, don't care about readability or maintanability and have disabled NOTICES and WARNINGS, you may write $bob=substr($bob,0,strrpos($bob,'-')); |
