Split(), Explode()..

Hello list, I have a simple (hopefully) question: I am trying to reformat the string by letters: $string = explode("", 'Hello World'); echo implode (' ', $string); What I want is to separate each character of the string by whitespaces. Plus I want to keep the array ($string) for feature use. The code above gives me the following errors: Warning: Empty delimiter in /blah/blah.html on line 93 Warning: Bad arguments to implode() in /blah/blah.html on line 94 I also tried to use split: $string = split ("", 'Hello World'); echo implode (' ', $string); and the errors received were: Warning: unexpected regex error (14) in /blah/blah.html on line 93 Warning: Bad arguments to implode() in /blah/blah.html on line 94 Anyone has an idea how to do it? Any function I don't know that does that? Can a loop help me? Regex? (BTW, the speed is pretty important) Thanks folks!
