I've an array like this:
8:16, 9:8, 10:11, 11:5, 12:5, 13:13, 14:42
and I want it to be:
0:16, 1:8, 2:11 ....
in PHP.
I know I can do an own function. but I think it should be one built in.
I've tried: array_values

Please try this i think its your exact requirement.
$arr = array('8:16', '9:8','10:11');
$i=0;
foreach($arr as $val){
$arr1 = explode(':',$val);
$arr2[] = $i.":".$arr1[1];
$i++;
}
print_r($arr2);

good point, I think everyone has assumed
0:1, 1:2 was pseudo for array(1,2) - never considered OP meant literally.You can use natsort()

doesn't answer the question mate - he's not asking for the array to be sorted (though the title is misleading), he's asking for the existing values to be numerical/zero-indexed.
Use
array_values($yourArray);
I think it should work properly.

I think @Praveenkalal sussed what you meant, but I'll just add another alternative:
$i = 0;
array_walk($array, function(&$v) use(&$i) {
$v = preg_replace('/\d+:(\d+)/', ($i++).':$1', $v);
});
Alternatively, if you're array is already zero-indexed like we have assumed this will work:
foreach($array as $key => &$val)
$val = preg_replace('/\d+:(\d+)/', $key.':$1', $val);
arrays... fun fun fun
Just to clarify - there's no built-in function because what you are doing is too specific - if your array values are key:value pairs then normally you'd have mapped them to an array as such - which is why we all thought array_values would be sufficient.
For example if your data was in a format like:
$array = array(
8 => 16,
9 => 8,
10 => 11,
...
);
you'd have the full range of php's internal functionality available to you.
array_values()is absolutely correct.
