I've var dumped my array:
array(4) { [0]=> string(72) " 1 " [1]=> string(57) " 2 " [2]=> string(63) " › " [3]=> string(63) " » " } When I check:
empty($myArray); It always says true. Why is this?

- empty() function returns FALSE if var exists and has a non-empty, non-zero value. Otherwise returns TRUE.
- The following things are considered to be empty, and return value would be true:
- "" (an empty string)
- 0 (0 as an integer)
- "0" (0 as a string)
- NULL
- FALSE
- array() (an empty array)

How does it help in this case? We all see array is not empty.
Alternatively,you can check with count() function like this:-
if((count($myArray) < 1) || (count($myArray)) === 0){ echo 'Array is empty'; }else{ echo 'There is Data in Array'; } 3 Comments

Not true.
$myArray is variable, isn't it? Empty function works also for arrays: The following things are considered to be empty: array() (an empty array)
Mubo
I didn't say you can't use it. but the empty function works some times delivers not the expected result. if used count(), with arrays that is more reliable. What i have wrote is the exact explanation on the php site. If you you are more knowledgeable in it. prove me wrong.
