Strings and Arrays

I read somewhere in the annotated manual that strings are character arrays. I am very unfamiliar with the use of arrays in PHP, so I am wondering if someone could throw me a quick pointer or two. I want to print a modified block of html code for each letter in a string. So if I create a function that can be passed the string itself, how would I print out the block of code for each individual letter in the array? This is the code I tried to use, but it did not work: function unnamed( $word ) { GLOBAL $val; reset ( $word ); while (list ($val) = each ($word)) { echo "HTML CODE FOR EACH LETTER"; } Thanks!
