array_push is couting the value instead of adding

Question

When I insert the value to the array its counting the value instaed of adding.

I have the below array named $staff_group_arr

Array ( [0] => All Rights User [1] => Operation [2] => Supritendent [3] => Admin Department [4] => Accounts [5] => Transportation )

I am donig like this

$glo_staff_array = array_push($staff_group_arr, "Global", "Managers");

print_r($glo_staff_array );

Result is coming as 8

Please let me know where is the fault.

Answer 1

Read the documentation:

Description

int array_push ( array &$array , mixed $value1 [, mixed $... ] )

Return Values

Returns the new number of elements in the array.

The ampersand, &, is the reference operator. This means that the function will modify the parameter, as opposed to returning a modified version of the parameter:

array_push($staff_group_arr, "Global", "Managers");
print_r($staff_group_arr);

You can also append stuff the simple way:

$staff_group_arr[] = 'Global';
$staff_group_arr[] = 'Managers';
print_r($staff_group_arr);

Answer 2

array_push returns new number of elements in the array. If you wan to see your new array do:

print_r($staff_group_arr);
