In PHP, if the mysql database server cannot be connected,
for example database server is handed or turned off,
an error message will be displayed:
Warning: mysql_connect(): Unknown MySQL Server Host "mysql.example.com" ...

My question is how to not display this warning message?
or can I customise the error message?
if so, how?

Thank you.

This should suppress most messages. Unless there is a die() message coded in and there probably is.

@mysql_connect():

Look for mysql_connect();
and change to:
@mysql_connect() or die("Sorry Server Error");

however, you may want to investigate why you are getting an error message.

Hope this helps!

PHP also provides a mysql function to determine the error. The function is as follows: mysql_error(). It takes no parameters. If you want to use this information, you can either store it to a file or display it on the webpage. Follow this code:

Problem fixed...
thank you so much.

here is my statement:
$db_link = @mysql_connect($db_host,$db_username,$db_password) or die("Cann't Connect to Database.\n");

That'll do it. Whenever you need to debug a script, remember the die() function. Most scripting languages have it and it is very useful.
