将mysql转换为mysqli? [英] Convert mysql to mysqli?

问题描述

我正在尝试将代码更改为mysqli，听说不推荐使用mysql，并且在将代码更改为mysqli时遇到了麻烦.

I'm trying to change my code to mysqli, I heard mysql isn't recommended and I'm having trouble changing my code to mysqli.

我设法连接到我的数据库，但是其余代码似乎不起作用，我尝试将所有mysql更改为mysqli，但是没有用.我该怎么做，所以代码可以在mysqli中正常工作?

I managed to connect to my database but the rest of the code doesn't seem to work, I tried changing all mysql to mysqli but it didn't work. What could I do so the code works the same but in mysqli?

有人可以重写它，以便我看到其中的区别.我还没有看过任何好的教程.

Could someone rewrite it so I could see the difference. I haven't seen any good tutorials.

<?php
 $db = new mysqli('localhost','root', '', 'searchengine');

    if($db->connect_errno) {
        die('sorry we are having some problbems');
        }

$sql = mysql_query(sprintf(
    "SELECT * FROM searchengine WHERE pagecontent LIKE '%s' LIMIT 0,%d",
        '%'. mysql_real_escape_string($_GET['term']) .'%',
        mysql_real_escape_string($_GET['results']))
);

while($ser = mysql_fetch_array($sql)) {
    echo "<h2><a href='$ser[pageurl]'>$ser[pageurl]</a></h2>";
}

mysql_close();

        '%'. $db->real_escape_string($_GET['term']) .'%',
        $db->real_escape_string($_GET['results']))

}

$db->close();
