I have this array, I want to remove the empty values
////
Array ( [55119901] => 3 [55219902] => 3 [17110405] => 1 [] => 3)
////
I want to delete the empty key/value
////
[] =>3
////
So I will end up with this array as a reusult
////
Array ( [55119901] => 3 [55219902] => 3 [17110405] => 1)
////
What is the array function for that task, I can't figure it out.
Thanks in advance for your help
I don't know if a key can be empty. Even if you create array without explicit keys, they are created using integers.
But if it could, my algorithm would be:
- find all the keys in an array ([man]array_keys()[/man])
- for each key check if it's empty ([man]foreach[/man})
- if it's empty, [man]unset[/man] that element - that's when it comes to some trouble - how to unset it when the key is already empty.
it is perfectly legal to have an empty array key. just use [man]unset[/man] as you would any other array key:
$array = array(
'1' => 'one',
'2' => 'two',
'' => 'nothing',
'3' => 'three',
'4' => 'four'
);
unset($array['']);
print_r($array);
