Lets say I'm having the following php array

Array(
[0]=>a,b,c
)

how can I convert it to get as result another array, what should look like

Array(

[0]=>a

[1]=>b

[2]=>c
)

---

// $a = array('a,b,c');
$b = explode(',', $a[0])

---

You can simple use php explode() function for that.explode(",", $somearray[0]);.

This is the way to create index array if you want to give first index of your array whatever you want rather than 0.

Array(
[0]=>'a','b','c'
)

So if you want to start you first index from 10 than.

 Array(
   [10]=>'a','b','c'
 )

will result like this

 Array(
    [10]=>'a',
    [11]=>'b',
    [12]=>'c'
    )
