php mysql connection problem

[alokp99]

Hi,

I am using php5.2.3 with iis and mysql5.0 on win xp.I downloaded  installed php,mysql and uncommented php_mysql.dll in the php.ini file which is in windows folder.when i try to run the testmysql connection it just throws up a blank page. does not give me any errors.i cant think of anything.i have used php and mysql before and never faced such a problem.Do you think it has something to do with the norton firewall.I can seem to understand.

Thanks,

Alok.

It has nothing to do with your firewall, but with how PHP loads the mysql extensions. In order for the mysql extension to function correctly PHP needs to be able to find an external library called libmysql.dll. This file should be located in the root of the PHP Installation folder.

 

Make sure you have done the following.

 

- Added PHP to the PATH Environment Variable.

- Ensured PHP is reading the php.ini you're editing

- Setup extension_dir to point to PHP's extension folder

[alokp99]

i added c:\php; to the PATH variable and also edited php.ini to point to the C:\php\ext folder.I copied libmysql.dll to system folder.But still the same result.A blank page.do you think there is some problem with the libmysql.dll file?Should I get another copy of it and try?

Set display_errors = On in your php.ini and stop and start the web server to get any changes made to php.ini to take effect. When learning php, developing php code, or debugging php code, you need this on anyway.

 

This will both tell you if the php.ini is actually getting loaded (the phpinfo() output states that the one being loaded is where you stated you put yours) and it will hopefully tell you why the code is not working. The blank page is either because of an undefined mysql function call or there could be something like a syntax error in the code.

 

Posting the code you are trying would help also.

Hi,

php is really freaking me out.I did set display_errors=on and it threw an fatal error mysql function not found error.So I checked my php.ini file and found that the php_mysql.dll,php_mysqli.dll were not uncommented.so i removed the ; and then it worked.But when I tried it after a hour or so I am back to square one with no errors being thrown. Why is this happening?

[alokp99]

<?php

$dbhost = 'localhost';

$dbuser = 'root';

$dbpass = 'hack';

$dbname = 'mystore';

 

$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql');

mysql_select_db($dbname);

 

$query='select * from users';

 

?>

This the code I am using to connect.

 

[PFMaBiSmAd]

If that is your whole code, it does not output anything. It connects to the database server, selects a database, makes an assignment to the variable $query, and ends.
