How to connect to MySQL database using PHP

MySQL Connection: Let be Expert

Originally I wrote a post about 1 year ago when I discovered some problems happened with me because of the MySQL connection fails. Now I have more experience with PHP/MySQL.I have decided to visit this topic to connect to MySQL database using PHP.

Let’s start to see one by one

You should use mysql_pconnect instead of mysql_connect because,mysql_pconnect() acts very much like mysql_connect() with two major differences.

First, when connecting, the function would first try to find a (persistent) link that’s already open with the same host, username, and password. If one is found, an identifier for it will be returned instead of opening a new connection.

Second, the connection to the SQL server will not be closed when the execution of the script ends. Instead, the link will remain open for future use (mysql_close() will not close links established by mysql_pconnect()).

This type of link is therefore called ‘persistent’.

You should suppress the error message on failure by prepending a @ to the function name.

Above code is for if any error occurs while the connection is executing and here, I have called one function CustomCriticalError. Let’s see how function works!!

Here, In above function CustomCriticalError, I have logged the error in the file and also to send E-mail and SMS if the connection fails.I have explained all the codes in a comment.
