Regular Expression to array with string issue

Question

Having a little issue with RegEx, I have the strings

AM.name:ASC,AMAdvanced.start:DESC,

AMAdvanced.start:DESC,AM.Genre:Action

and need to break them into

array(0){

AM.name => ASC,

AMAdvanced.start => DESC
}

and 

array(0){

AMAdvanced.start => DESC,

AM.Genre => Action

}

Any help would be fantastic since completely new to regex

Answer 1

No need of regex here.

Steps:

1. explode by comma ,
2. Loop over exploded array
3. Explode by colon :
4. Push into new array

Code:

$newArr = array();
foreach (explode(',', trim($str, " ,")) AS $el) {
    $el = explode(':', $el);
    $newArr[$el[0]] = $el[1];
}
print_r($newArr);
