To get PHP to execute the statement above we must use mysqli_query () function. This function is used to send a query or command MySQL connection.


Look at the following "Persons" table:

FirstName LastName Age
Peter Griffin 35
Glenn Quagmire 33

The following examples delete "Persons" table all LastName = 'Griffin' records:

// 检测连接
if (mysqli_connect_errno())
	echo "连接失败: " . mysqli_connect_error();

mysqli_query($con,"DELETE FROM Persons WHERE LastName='Griffin'");


After this remove, "Persons" table is as follows:

FirstName LastName Age
Glenn Quagmire 33
