问题

您好,我正在创建一个搜索功能,允许用户搜索特定的电子号码,看看它是否来自动物。首先,我想将所有结果转储到网页上,看看它是否100%正确。我已成功使用PHP在我的网站上连接数据库,但pg_query没有显示任何结果,是否需要更多代码?

守则

<?php
        $conn = pg_connect("***** port=*****
            dbname=***** user=***** password=*****");
        $res  = pg_query($conn, "SELECT * FROM enumbers");


        $connection = pg_connect ("host=***** port=*****
            dbname=***** user=***** password=*****");
        if($connection) {
            echo 'connected';
        } else {
            echo 'there has been an error connecting';
        } 
?>

感谢@LaurenzAlbe指导我answer,我想我会在这里展示:

<?php       
        // Connecting, selecting database
        $dbconn = pg_connect("host=***** port=*****
            dbname=***** user=***** password=*****")
            or die('Could not connect: ' . pg_last_error());    

        // Performing SQL query
        $query = 'SELECT * FROM enumbers';
        $result = pg_query($query) or die('Query failed: ' . pg_last_error());

        // Printing results in HTML
        echo "<table>\n";
        while ($line = pg_fetch_array($result, null, PGSQL_ASSOC)) {
            echo "\t<tr>\n";
            foreach ($line as $col_value) {
                echo "\t\t<td>$col_value</td>\n";
            }
            echo "\t</tr>\n";
        }
        echo "</table>\n";
?>

正如您在上面的代码中所看到的,我完全忘记了在HTML中实际打印结果,这就是没有出现的原因。
