PHP: mysql_connect() won't work via command line

Question

I have a script which calls mysql_connect() to connect to a MySQL DB. When I run the script in a browser, it works. However, when I run it from a command line

Answer 1

My system is CentOS. In my case, the the path to mysql.so is incorrect.

When I type

php -m

There is no mysql.

In my original /etc/php.d/mysql.ini there is only one line:

extension=mysql.so

So I use command:

rpm -ql php-mysql | grep mysql.so

to find out the correct path, which is

/usr/lib64/php/modules/mysql.so

then I replaced the line to :

extension=/usr/lib64/php/modules/mysql.so

then

service httpd restart 

and

php -m

mysql is now loaded.
