php: easy way to compare array

[unwashed potato!]

is there a better way to compare a string against an array other then using foreach...? always felt that although relatively simple this could still be done a lot easier but have never come across another way.

EDIT for some reason I read PHP but my brain thought perl! lol

if(grep {/$string/} @array){
print "OMFG String found\n";
} else{
print "Seriously no way! string not found\n";
}

Looks like PHP has something similar though, never used PHP so wouldn't listen to me though!

if(preg_grep("/string/",$array){
}

[/PHP]

What exactly are you trying to do? See what items are in one but not the other?

in_array

pretty much, see if the current id has been shown and if not show it, else continue to next id.

also of use are array_filter and array_walk

Or the array_intersect* or array_diff* functions.
