Within your first "for" loop, you are transversing through the $fields array.
The $i is starting with the first one "$fields[0]" and checking each of the
elements in that array until it gets to the last one.
While that "for" loop is running, the other "for" loop within it is transversing
the other array and using the "strpos" function to compare each element of
$badchars to the current element of $fields (generated from the primary "for"
loop). For each element of $fields, the $badchars array is being checked for a
match.
