From: Operating system: Ubuntu PHP version: Irrelevant Package: Arrays related Bug Type: Bug Bug description:array_keys convert keys type
Description:
------------
I noticed when I extract the keys of an array using array_keys, if a key is
an string with a number, on the resulting array from the array_keys
execution I get an integer for this key instead of a string.
My version of PHP is 5.3.5-1ubuntu7.3.
Regards!
Test script:
---------------
$a = array(
'1' => 'apple',
'2' => 'banana',
'3' => 'orange',
'4' => 'stawberry',
);
$keys = array_keys($a);
echo gettype( $keys[0] );
Expected result:
----------------
Output:
string
Actual result:
--------------
Output
integer
