Question

您好，我在网站上搜索时遇到此错误。

致命错误：未捕获错误：在/home/u321547826/public_html/search.php:14中调用未定义函数mysql_connect（）堆栈跟踪：#h {main}在/home/u321547826/public_html/search.php中引发第14行

我正在使用此代码，任何人都可以提供帮助吗？

<?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>
    ";

            }
        }

    }
}

?>

Answer 1

您可能正在使用PHP＆gt; = 7其中mysql_函数不再被弃用且已被删除，请尝试使用mysqli_或PDO。

Answer 2

检查PHP版本，尝试使用mysqli_connect（）

警告此扩展在PHP 5.5.0中已弃用，并且已在PHP 7.0.0中删除。相反，应该使用MySQLi或PDO_MySQL扩展。另请参阅MySQL：选择API指南和相关的常见问题解答以获取更多信息。该功能的替代方案包括： mysqli_connect（） PDO :: __构建体（）
