With Print_r ($arr);
Output: Array ([0] = 1,3,2)
With Var_dump ($arr);
Output: Array (1) {[0]=> string (5) "1,3,2"}
The For loop output gets
for ($i = 0; $i echo $arr [$i];
}
Output:
Comma actually also traversed out of there
What is the structure of this number, how can I take this for loop time to remove the comma?
Only this structure is exported:
