Question

I need to make big string into a nice array. String itself is list of tags and tag ids. There can be any amount of them. Here is example of the string: 29:funny,30:humor,2:lol – id:tag_name. Now, I have problem converting it to array – Array ( [29] => funny [30] => humor ). I can get to the part where tags are as so

Array (

[0] = Array (

[0] = 29

[1] = funny

)

[1] = Array (

[0] = 30

[1] = humor

)

)

I’ve look at array functions too but seems none of them could help me.
Can anyone help me out?

Here’s some code to get you going:

$str = "29:funny,30:humor,2:lol";
$arr = array();
foreach (explode(',', $str) as $v) {
    list($key, $val) = explode(':', $v);
    $arr[$key] = $val;
}
print_r($arr);
/* will output:
Array
(
    [29] => funny
    [30] => humor
    [2] => lol
)
*/

You could replace the foreach with an array_map for example, but I think it’s simpler for you this way.
