It would seem like this could be optimized in the language during runtime (if $var++ is the only thing in the whole statement, it could be treated as ++$var). When using the ++ operator by itself on a variable, ++$var is faster than $var++ and uses slightly less memory (in my experiments). Incrementar o decrementar otras variables de caracteres no tiene efecto, el Nótese que las variables de caracteres pueden ser incrementadas pero no decrementadas yĪun así sólo caracteres y dígitos de ASCII puro (a-z, A-Z y 0-9) están soportados. (el valor ASCII de 'Z' es 90, el valor ASCII de '[' es 91). $a = 'Z' $a++ convierte $a en 'AA', mientras que en C Sobre variables de caracteres y no la de C. PHP sigue la convención de Perl cuando trabaja con operaciones aritméticas
