[ad_1] “Unreachable statement” means that there is no path in your code that can get you to this line in your program. It has nothing to do with protected fields.

[ad_1] Instead of having a bunch of ifs, try making a map of numbers to letters. $map = array( 1 => ‘A’, 5 => ‘B’, 9 => ‘C’ ); for($i=1; $i <= 10; $i++){ // If the value is in the map, print the letter, // otherwise print the number echo array_key_exists($i, $map) ? $map[$i] … Read more
