php - Increment char in for loop -

-

i know how can make : php function exists ? 

for ($i=0; $i < 26; $i++) {      // echoes "a" ... b ... c ... }

php supports perl-style character incrementing

so use

for($char = 'a'; $char !== 'iw'; $char++) {     echo $char, php_eol; }

which print out a iv.... important use !== in terminating comparison though
