Question

I have an array:

Array
(
 [0] => ololo
 [2] => test
 [3] => haha
 [7] => nice
)

How can I change the indexes of the array to this:

Array
(
 [0] => ololo
 [1] => test
 [2] => haha
 [3] => nice
)

Answer 1

From PHP.net:

array_values() returns all the values from the input array and indexes the array numerically.

$arr = array_values($arr);
