Ultra Easy: Check if an array contains at least one key

[johnsmith153]

I need to check if an array contains at least one key.

 

I wont know the values of the keys (could be 34434, 20, anything)

 

but need to know if at least one value exist.

 

It is to stop " Warning: array_key_exists() [function.array-key-exists]: The second argument should be either an array or an object " when my array is empty

[DarkWater]

if (count($array) > 0) {
...
}

I should have know that! - pretty obvious.

 

I tried if $array="" then got fed up.

 

Cheers Darks.
