PHP

Rather than have to go to php.net every time I need to look up some function or other I write down my favourites here.

Because I can never remember where the needle and haystack go...:

string substr ( string $string , int $start [, int $length ] )

Link

int substr_count ( string $haystack , string $needle [, int $offset [, int $length ]] )

Link

mixed substr_replace ( mixed $string , string $replacement , int $start [, int $length ] )

Link

array explode ( string $delimiter , string $string [, int $limit ] )

Link

string implode ( string $glue , array $pieces )
