范例
Example #1 面向对象风格
<?php /* Open a connection */ $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $mysqli->query("CREATE TABLE myCountry LIKE Country"); $mysqli->query("INSERT INTO myCountry SELECT * FROM Country"); $query = "SELECT Name, Code FROM myCountry ORDER BY Name"; if ($stmt = $mysqli->prepare($query)) { /* drop table */ $mysqli->query("DROP TABLE myCountry"); /* execute query */ $stmt->execute(); echo "Error:\n"; print_r($stmt->error_list); /* close statement */ $stmt->close(); } /* close connection */ $mysqli->close(); ?>
Example #2 过程化风格
<?php /* Open a connection */ $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } mysqli_query($link, "CREATE TABLE myCountry LIKE Country"); mysqli_query($link, "INSERT INTO myCountry SELECT * FROM Country"); $query = "SELECT Name, Code FROM myCountry ORDER BY Name"; if ($stmt = mysqli_prepare($link, $query)) { /* drop table */ mysqli_query($link, "DROP TABLE myCountry"); /* execute query */ mysqli_stmt_execute($stmt); echo "Error:\n"; print_r(mysql_stmt_error_list($stmt)); /* close statement */ mysqli_stmt_close($stmt); } /* close connection */ mysqli_close($link); ?>
以上例程会输出:
Array ( [0] => Array ( [errno] => 1146 [sqlstate] => 42S02 [error] => Table 'world.myCountry' doesn't exist ) )
