<P>I need to divide a long string into an array of smaller chunks. If I use the function chunk_split(), I will need to use the function ereg_replace() or explode() to get the array. There is a problem though. What to use as a delimiter in chunk_split() that cannot already be in the long string? (e.g. If I use '\n' as the delimiter in chunk_split(), the string could have already contained some '\n' and therefore when I use explode(), I will get more chunks than I necessarily need.) </P> Well, this is the way I go around it.<br> $chunk_length = 250; $nr_chunks = ceil(strle ($long_string) / $chunk_length); for ($ix=0; $ix<$nr_chunks; $ix++) { $chunk[$ix] = substr ($long_string, $ix*$chunk_length, $chunk_length); } -- http://www.php.net/manual/en/function.chunk-split.php http://master.php.net/manage/user-notes.php?action=edit+16771 http://master.php.net/manage/user-notes.php?action=delete+16771 http://master.php.net/manage/user-notes.php?action=reject+16771
