Question

Is there a way to check if all the elements in an array are null in PHP?

For instance, I have an array array(null,null,null,null) – is there a way to check this scenario?

I am looking for a better way than just looping through the entire array and checking each element.

Another simple way of making this work is to use the max() function.

max(array( 3, 4, null, null  ) )      # is 4
max(array( null, null, null, null)    # is null

Thus you can issue a simple if( is_null(max($array)) ) { ... } call.
