Hello,
mysqli_pconnect[] function is used for making a persistence connection with the database that does not terminate when the script ends.
mysqli_connect[] function searches any existing persistence connection first and if no persistence connection exists, then it will create a new database connection and terminate the connection at the end of the script.
Sample code:
$DBconnection = mysqli_connect["localhost","username","password","dbname"]; // Check for valid connection if [mysqli_connect_errno[]] { echo "Unable to connect with MySQL: " . mysqli_connect_error[]; }
mysqli_pconnect[] function is depreciated in the new version of PHP, but you can create persistence connection using mysqli_connect with the prefix p.
Thank You!!

Which connection is better and how are they anycodings_mysql fundamentally different when connecting?

They're not interchangeable. There are anycodings_php different extensions to access MySQL anycodings_php databases.
See anycodings_php //ca2.php.net/manual/en/book.mysqli.php anycodings_php and anycodings_php //ca2.php.net/manual/en/book.mysql.php.

Check out the documentation: anycodings_php //ca3.php.net/manual/en/mysqli.overview.php
From the section "What is PHP's mysqli anycodings_php Extension?"
The mysqli extension, or as it anycodings_php is sometimes known, the MySQL anycodings_php improved extension, was developed to anycodings_php take advantage of new features found anycodings_php in MySQL systems versions 4.1.3 anycodings_php and newer. The mysqli extension anycodings_php is included with PHP versions 5 anycodings_php and later.
There are several important differences anycodings_php between the two libraries:
- Mysqli supports charsets, mysql does not

MySQL and MySQLi are two separate PHP anycodings_php extensions, MySQLi being the newer anycodings_php one. Although the connect functions may anycodings_php be interchangeable, I would disadvise to anycodings_php do so!
MySQLi provides a object-oriented way anycodings_php for accessing MySQL databases.
in short: if you use mysql_query[], you anycodings_php should use mysql_connect[] to connect to anycodings_php your server.
Others already postet links to the PHP anycodings_php manual.

Mysqli_connect is the newer version of anycodings_php mysql library.
Here I in mysqli stands for improved.
Few things have been introduced with anycodings_php Mysqli.
They are,
-Prepared statements.
-Object oriented interface.
-Support for multiple statements.
-Embedded server support.
The mysqli extension has a number of anycodings_php benefits, the key enhancements over the anycodings_php mysql extension being:
-Object-oriented interface
-Support for Prepared Statements
-Support for Multiple Statements
-Support for Transactions
-Enhanced debugging capabilities
-Embedded server support
So Mysql_connect[] basically is the anycodings_php database connector to Mysql whereas anycodings_php Mysqli_connect[] is the connector for anycodings_php Mysqli databse
