范例

Example #1 面向对象风格

<?php $mysqli = new mysqli("127.0.0.1", "user", "password", "world"); if($mysqli->connect_error){    die("$mysqli->connect_errno: $mysqli->connect_error");}$query = "SELECT Name, Population, Continent FROM Country WHERE Continent=? ORDER BY Name LIMIT 1";$stmt = $mysqli->stmt_init();if(!$stmt->prepare($query)){    print "Failed to prepare statement\n";}else{    $stmt->bind_param("s", $continent);    $continent_array = array('Europe','Africa','Asia','North America');    foreach($continent_array as $continent)    {        $stmt->execute();        $result = $stmt->get_result();        while ($row = $result->fetch_array(MYSQLI_NUM))        {            foreach ($row as $r)            {                print "$r ";            }            print "\n";        }    }}$stmt->close();$mysqli->close();?>

Example #2 过程化风格

<?php $link = mysqli_connect("127.0.0.1", "user", "password", "world"); if (!$link){    $error = mysqli_connect_error();    $errno = mysqli_connect_errno();    print "$errno: $error\n";    exit();}$query = "SELECT Name, Population, Continent FROM Country WHERE Continent=? ORDER BY Name LIMIT 1";$stmt = mysqli_stmt_init($link);if(!mysqli_stmt_prepare($stmt, $query)){    print "Failed to prepare statement\n";}else{    mysqli_stmt_bind_param($stmt, "s", $continent);    $continent_array = array('Europe','Africa','Asia','North America');    foreach($continent_array as $continent)    {        mysqli_stmt_execute($stmt);        $result = mysqli_stmt_get_result($stmt);        while ($row = mysqli_fetch_array($result, MYSQLI_NUM))        {            foreach ($row as $r)            {                print "$r ";            }            print "\n";        }    }}mysqli_stmt_close($stmt);mysqli_close($link);?>
