[PHP] mazani session

1
session_unset($Kosik["Card"]);
session_unset($Kosik["Volume"]);
session_unset($Kosik["Name"]);

2.
session_unset("Kosik");

az uz dam 1 nebo 2 tak mi to funguje spolehlive na mym compu

ale jakmile to nahraju na web

Fatal error: Maximum execution time of 30 seconds exceeded in /home/pristin/public_html/bleee/data/preq.php on line 63

Warning: Unknown list entry type in request shutdown (0) in Unknown on line 0

Warning: Unknown list entry type in request shutdown (0) in Unknown on line 0"

maximalni doba delky trvani skriptu je nastavena na 30s
A tvuj skript potrebuje dele, takze je po 30s zastaven

takze:
void session_unset ( void ) - tahle funkce maze vsechny promene ze session
a
pokud chces odregistrovat ze sessionu urcitou promenou tak :
session_unregister ( string name) , pozor nedavej tam primo promenou, ale jen jeji nazev takze:
session_unregister ('Kosik');
