PHP array rename keys

Question

I have an array like this, the keys are epoch timestamps they were used to order the files by date i now want to rename the keys to 0, 1, 2, 3, etc

Array($files)
(
 [1365168386] => _MG_5704.jpg
 [1368201277] => _MG_5702.jpg
 [1368201719] => jetty.jpg
 [1368202375] => _MG_6100.jpg
 [1368202758] => _MG_5823.jpg
 [1368203032] => _MG_5999.jpg
 [1368203244] => _MG_5794.jpg
 [1368203477] => _MG_5862.jpg
 [1368203727] => _MG_6028.jpg
)

so it becomes

Array($files)
(
 [0] => _MG_5704.jpg
 [1] => _MG_5702.jpg
 [2] => jetty.jpg
 [3] => _MG_6100.jpg
 [4] => _MG_5823.jpg
 [5] => _MG_5999.jpg
 [6] => _MG_5794.jpg
 [7] => _MG_5862.jpg
 [8] => _MG_6028.jpg
)

• Marcel Korpel: Please show what you have tried yourself.
• moonwave99: You want to hear about array_values.

Answer 1

array_values returns a numeric array, starting from 0: http://php.net/array_values

$files = array_values($files);

array_values also maintains the order.

• user1869566: Thanks, i'd done it using a loop but knew there was a function that would do it in one go but just couldn't find it.

Answer 2

$files = array_map('array_values', $files);

This will reset all your key values in your array.

• bwoebi: what? array_values on the string values of the array?
• deco20: @bwoebi correct me if I am wrong, it is late here haha, but the 'array_values' part is a callback function and will be applied to each array element in $files?
• bwoebi: array_values expects an array as parameter, not the values of the array. But array_map passes the values of each entry to array_values. Try it yourself...
• deco20: @bwoebi array_values() expects parameter 1 to be array is what I was getting
