Hi
In PHP, will these always return the same values?
//example 1 $array = array(); if ($array) { echo 'the array has items'; } // example 2 $array = array(); if (count($array)) { echo 'the array has items'; }
Thank you!

What i would do is get);
That will show you the entire contents of the array, and you can see what is exactly in it.
Sounds like the data in the array is not what your expecting it to be.

How can I count the number of elements in an array, because contrary to logic array.count(string) does not count all the elements in the array, it just searches for the number of occurrences of string.

Len(myArray)
Or,
myArray.__len__()
if you want to be oopy; "len(myArray)" is a lot easier to type! :)
len is a built-in function that calls the given container object's __len__ member function to get the number of elements in the object .
