Checking if a value is repeated in an array

[odysseyphotography]

Hi everyone,

I was wondering if its possible to check if a given value appears in
an array more than once?

I need to code something which goes something along the lines of:

Faux code ---

if (in_array_twice ($person, $already_emaile d)) {
echo $person . ' is in the array already, don't email them';
} else {
echo $person . ' is not in the array, its OK to email them';
}

---

If anyone has any ideas they'd be very much appreciated.

Thanks,

OP

function in_array_moreth anonce($needle, array $haystack, $strict =
false) {
return (count(array_ke ys($haystack, $needle, $strict)) 1);
}
