note 103059 added to function.explode

while explode() and implode() are counterparts, note that it does NOT work for an empty delimiter! solution: use str_split($str) instead of explode('', $str) example: <?php $str1 = 'abc'; var_dump($str1); $str2 = implode(',' , explode(',' , $str1)); // OK (explode with non-empty delimiter) var_dump($str2); $str3 = implode('' , str_split($str1)); // OK (str_split) var_dump($str3); $str4 = implode('' , explode('' , $str1)); // ERROR! (explode with empty delimiter) var_dump($str4); ?> returns: string 'abc' (length=3) string 'abc' (length=3) string 'abc' (length=3) Warning: explode() [function.explode]: Empty delimiter.
