例子
Example #1 Object oriented style
<?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 Procedural style
<?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);
?>上面的例子会输出：
Array
(
[0] => Array
(
[errno] => 1146
[sqlstate] => 42S02
[error] => Table 'world.myCountry' doesn't exist
