PHP VersionThis function was first introduced in PHP Version 5 and works works in all the later versions. ExampleFollowing example demonstrates the usage of the mysqli_refresh() function (in procedural style) − Assume we have created a table named my_team in the database mydb, as follows − CREATE TABLE my_team( ID INT PRIMARY KEY AUTO_INCREMENT, First_Name VARCHAR(255), Last_Name VARCHAR(255), Place_Of_Birth VARCHAR(255), Country VARCHAR(255) ); Following example turn the auto commit option off and tries to insert records into this table − <?php //Creating a connection $con = mysqli_connect("localhost", "root", "password", "mydb"); //Setting auto commit to true mysqli_autocommit($con, False); //Inserting a records into the my_team table mysqli_query($con, "insert into my_team values(1, 'Shikhar', 'Dhawan', 'Delhi', 'India')"); mysqli_query($con, "insert into my_team values(2, 'Jonathan', 'Trott', 'CapeTown', 'SouthAfrica')"); mysqli_query($con, "insert into my_team values(3, 'Kumara', 'Sangakkara', 'Matale', 'Srilanka')"); mysqli_query($con, "insert into my_team values(4, 'Virat', 'Kohli', 'Delhi', 'India')"); //Closing the connection mysqli_close($con); ?> Since we have turned the auto-commit option off, The records add will not be saved in the database and, if you verify the contents of the table in MySQL, it will be empty as shown below $minus; mysql> select * from my_team; Empty set (0.00 sec) You can flush the records into the table by using the mysqli_query function as shown below $minus; <?php //Creating a connection $con = mysqli_connect("localhost", "root", "password", "mydb"); //Setting auto commit to true mysqli_autocommit($con, False); //Inserting a records into the my_team table mysqli_query($con, "insert into my_team values(1, 'Shikhar', 'Dhawan', 'Delhi', 'India')"); mysqli_query($con, "insert into my_team values(2, 'Jonathan', 'Trott', 'CapeTown', 'SouthAfrica')"); mysqli_query($con, "insert into my_team values(3, 'Kumara', 'Sangakkara', 'Matale', 'Srilanka')"); mysqli_query($con, "insert into my_team values(4, 'Virat', 'Kohli', 'Delhi', 'India')"); mysqli_refresh($con, MYSQLI_REFRESH_TABLES); //Closing the connection mysqli_close($con); Now, if you and verify the contents of the table my_team then, you can see the inserted records as shown below − mysql> select * from my_team; +----+------------+------------+----------------+-------------+ | ID | First_Name | Last_Name | Place_Of_Birth | Country | +----+------------+------------+----------------+-------------+ | 1 | Shikhar | Dhawan | Delhi | India | | 2 | Jonathan | Trott | CapeTown | SouthAfrica | | 3 | Kumara | Sangakkara | Matale | Srilanka | | 4 | Virat | Kohli | Delhi | India | +----+------------+------------+----------------+-------------+ 4 rows in set (0.00 sec) ExampleIn object oriented style the syntax of this function is $con->refresh(); Following is the example of this function in object oriented style $minus; <?php $con = new mysqli("localhost", "root", "password", "mydb"); //Inserting a records into the players table $con->query("CREATE TABLE IF NOT EXISTS players(First_Name VARCHAR(255), Last_Name VARCHAR(255), Country VARCHAR(255))"); //Turning the auto-commit false $con->autocommit(FALSE); $con->query("insert into players values('Shikhar', 'Dhawan', 'India')"); $con->query("insert into players values('Jonathan', 'Trott', 'SouthAfrica')"); //refreshing the table $con->refresh(MYSQLI_REFRESH_TABLES); //Closing the connection $res = $con -> close(); ?> This will produce following result − Data Created...... If you observe the contents of the table in the database you can see the inserted records as shown below − mysql> select * from players; +------------+-----------+-------------+ | First_Name | Last_Name | Country | +------------+-----------+-------------+ | Shikhar | Dhawan | India | | Jonathan | Trott | SouthAfrica | +------------+-----------+-------------+ 2 rows in set (0.00 sec) Example<?php $connection_mysql = mysqli_connect("localhost","username","password","db"); if (mysqli_connect_errno($connection_mysql)){ echo "Failed to connect to MySQL: " . mysqli_connect_error(); } mysqli_refresh($connection_mysql,MYSQLI_REFRESH_LOG); mysqli_close($connection_mysql); ?> php_function_reference.htm How to refresh table in PHP?PHP mysqli_refresh() Function
