A brief introduction to the MYSQLI_PHP tutorial introduced in PHP5

In the newly downloaded PHP5, you will find an extra mysqli.dll. What is it used for? Let me briefly introduce it. . . mysqli.dll is PHP's extended support for new features of mysql. In PHP5, it can be loaded in php.ini, as shown below: The i after mysql refers to improved, interface, ingenious, incompatible or incomplete (the extension is still under development, because neither MYSQL4.1 nor MYSQL5 has been officially launched and is still under development. , the new features have not been fully implemented) The specific goals mysqli wants to achieve are: - Easier maintenance - Better compatibility - Backward compatibility MySQL (referring to modules in PHP) has developed to a point where it seems messy and it is necessary to re- Do some sorting. At the same time, it is necessary to keep up with the development pace of MYSQL (DBMS), add support for new features, and adapt to future versions of MYSQL (DBMS). So mysqli.dll was born. Features of mysqli.dll: - Can be used in the same way as mysql.dll - Supports OO interface, simple call - Supports new features introduced by MYSQL4.1 - Through related functions such as mysqli_init(), you can Example of using mysqli to set advanced connection options: 1. The same method as before for mysql.dll: Output results: Very large cities are: Mumbai (Bombay) (10500000) Seoul (9981619) São Paulo (9968485) Shanghai (9696300) ) Jakarta (9604900) 2. Call using the built-in OO interface: query(SELECT Name, Population FROM City ORDER BY Population DESC LIMIT 5)) { print("Very large cities are:n"); /* Fetch the results of the query */ while( $row = $result->fetch_assoc() ){ printf("%s (%s)n", $row[Name], $row[Population]); } /* Destroy the result set and free the memory used for it */ $result->close(); } /* Close the connection */ $mysqli->close(); ?> New features supported include: Bound Parameters, Bound Results, etc. . . . If you are interested, you can directly refer to the original English: http://www.zend.com/php5/articles/php5-mysqli.php#fn3 Note: I feel that this is not useful for everyone. but. . . I believe it can help everyone understand more about the "changes" and better grasp the "trends" 8-)
