PHP错误问题(搜索)

Question

您好，我在我的网站上进行搜索时遇到此错误。

Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /home/u321547826/public_html/search.php:14 Stack trace: #0 {main} thrown in /home/u321547826/public_html/search.php on line 14

我正在使用这段代码，有人可以帮忙吗？

<?php

$button = $_GET['submit'];
$search = $_GET['search'];

if (!$button)
    echo "you didn't submit a keyword";
else {
    if (strlen($search) <= 1)
        echo "Search term too short";
    else {
        echo "You searched for <b>$search</b> <hr size='1'></br>";
        mysql_connect("", "", "");
        mysql_select_db("");

        $search_exploded = explode(" ", $search);

        foreach ($search_exploded as $search_each) {
            $x++;
            if ($x == 1)
                $construct .= "keywords LIKE '%$search_each%'";
            else
                $construct .= "AND keywords LIKE '%$search_each%'";

        }

        $construct = "SELECT * FROM SEARCH_ENGINE WHERE $construct";
        $run       = mysql_query($construct);

        $foundnum = mysql_num_rows($run);

        if ($foundnum == 0)
            echo "Sorry, there are no matching result for <b>$search</b>.</br></br>1. 
    Try more general words. for example: If you want to search 'how to create a website'
    then use general keyword like 'create' 'website'</br>2. Try different words with similar
     meaning</br>3. Please check your spelling";
        else {
            echo "$foundnum results found !<p>";

            while ($runrows = mysql_fetch_assoc($run)) {
                $title = $runrows['title'];
                $desc  = $runrows['description'];
                $url   = $runrows['url'];

                echo "
    <a href='$url'><b>$title</b></a><br>
    $desc<br>
    <a href='$url'>$url</a><p>
    ";

            }
        }

    }
}

?>

您可能正在使用 PHP>=7，其中 mysql_函数不再被弃用并已被删除，请尝试使用 mysqli_或 PDO相反。
