How to stop the script after an error

by **SimonEast** » Sun Dec 22, 2002 6:09 pm

Is there a way I can tell the script to stop when an error is produced? I'm pretty sure ASP automatically stops unless you tell it not to. I have a series of SQL queries and I don't want them to continue if the first didn't complete.

I suppose I could test for an error after every query, but is there a simpler way??

You can use this exit()

Code: Select all: <?php $filename = '/path/to/data-file'; $file = fopen ($filename, 'r') or exit("unable to open file ($filename)"); ?>

or you can use trigger_error() -->

Code: Select all: mysql_connect("localhost", "user", "database", "pass") or trigger_error("Could not connect to MySQL database", E_USER_ERROR);

or you can use die() -->

Code: Select all: mysql_connect("localhost", "user", "database", "pass")or die("Connect Error: ".mysql_error());

Importatnt!

When you use die() after an open <html> tag, don't forget to use die like this : die("blabla\n\n</body>\n\n</html>") ; This will close the body and html tags.

bye
