Replace preg_replace() e modifier with preg_replace_callback

Question

I\'m terrible with regular expressions. I\'m trying to replace this:

public static function camelize($word) {
   return preg_replace(\'/(^|_)([a-z])/e\', \'s         


        

Answer 1

You shouldn't use flag e (or eval in general).

You can also use T-Regx library

pattern('(^|_)([a-z])')->replace($word)->by()->group(2)->callback('strtoupper');
