Popis

-
Pripojenie k MySQL. Ak link identifier nie je zadaný, predpokladá sa posledné spojenie otvorené s mysql_connect(). Ak také spojenie nie je nájdené, pokúsi sa jedno vytvoriť ako keby bolo volané mysql_connect() bez argumentov. Ak sa náhodou nájde pripojenie, alebo je vytvorené, je vygenerované varovanie úrovne E_WARNING.
Vrátené hodnoty
Returns information about the statement on success, or FALSE on failure. See the example below for which statements provide information, and what the returned value may look like. Statements that are not listed will return FALSE.
