Suppose we have an array $a like this
Array ( [0] => abc [1] => dcf [2] => [3] => [4] => [5] => )
Here we need to check whether the array element is empty and pop that element.
We can easily achieve this by array_filter()
print_r(array_filter($a));
The output will be
Array ( [0] => abc [1] => dcf )
We can also write call back functions that can be passed as a parameter to array_filter() function.
