PHP array query? I'm probably just tired!

The function isn't coming to mind but I've been working for a while now so I'm probably just getting a blank but;


how would I check if variable $x exists within array $y[]

I know I could set up a loop to go through element of $y[] but is there a quick way to check it?

 

try...
$key = array_search('value', $array);

 

Use in_array()

if (in_array ($x, $y)){
print "It is there ";
}

Thanks guys, those are both useful
