面向对象风格
过程化风格
Returns an array of errors for the most recently invoked statement function that can succeed or fail.
A list of errors, each as an associative array containing the errno, error, and sqlstate.
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
)
)
