I have an array and in that array I have an array key that looks like, show_me_160
this array key may change a little, so sometimes the page may load and the array key maybe show_me_120
, I want to now is possible to just string match the array key up until the last _
so that I can check what the value is after the last underscore?
one solution i can think of:
foreach($myarray as $key=>$value){
if("show_me_" == substr($key,0,8)){
$number = substr($key,strrpos($key,'_'));
// do whatever you need to with $number...
}
}
