Question

I am trying to connect to a mysql db through php running on my schools unix server. This is what I am trying:

$ php setupDatabase.php 
PHP Fatal error:  Call to undefined function mysql_connect() in /users/cs/summers/Fall2010/webCentric/ass4/sessionTime/setupDatabase.php on line 16

Line 16 refers to this line:

db_server = mysql_connect($db_hostname, $db_username, $db_password);

I think this means that the mysql functions where not installed with php. When I execute <?php phpinfo(); exit(); ?> and grep for mysql this is what I get:

Configure Command =>  './configure'  '--build=x86_64-redhat-linux-gnu' '--host=x86_64-redhat-linux-gnu' ... '--with-mysql=shared,/usr' '--with-mysqli=shared,/usr/bin/mysql_config' '--with-pdo-mysql=shared,/usr' ...

I am not sure if this confirms that mysql is not installed.

Q: Am I missing mysql? Do I need to reinstall php with mysql?

Q: I do not have root access to server (obviously). Will I be able to install this without root access? If yes could someone point me to a tutorial?

Update

I just looked in my php.ini file this is what is contained in it regarding the mysql (I have removed comments and mysqli stuff).

[MySQL]
mysql.allow_persistent = Off
mysql.max_persistent = -1
mysql.max_links = -1
mysql.default_port =
mysql.default_socket =
mysql.default_host =
mysql.default_user =
mysql.default_password =
mysql.connect_timeout = 60
mysql.trace_mode = Off

The file does NOT contain: extension=mysql.so is this what is required to enable mysql? I do not have permissions to modify php.ini can I create another one somewhere or can I use something like an include statement with my code?

Answer 1

You have mysql extension disabled on your php.ini.

Edit your php.ini and uncomment (remove the 😉

; extension=mysql.so

In case you can’t edit php.ini, you can override it this way.
