I am trying to figure out a syntax that will replace each instance of % with
a different letter chosen randomly from the string $puzzle_filler.
$puzzle_filler is populated with the letters of the alphabet, roughly in the
same ratio as they are used.
This syntax replaces each instance of % with the same letter:
$puzzle[$i] = str_replace ( "%" , ( substr ( $puzzle_filler , rand(1,98) ,
1 ) ) , $puzzle[$i] );
Is there a way to tweak my str_replace so it will only do 1 % at a time, so
a different replacement letter is selected?
This is the syntax specific to choosing a replacement letter at random:
substr ( $puzzle_filler , rand(1,98) , 1 );
Thanks for your help.
