使用mysqli使用php连接数据库

Question

It's not working. The code i used is

    <?php
        $conn=mysqli_connect('127.0.0.1','root','');
        if(!$conn)
        {
            echo "Connection Not Established";
        }
        if(!mysqli_select_db($conn,'lpractice'))
        {
            echo "Database Not Found!";
        }
        $res=mysqli_query($conn,"select * from signup");
        echo "<table>";
            while($row= mysql_fetch_array($res))
            {
                echo "<tr>";
                echo "<td>" . $row['name'] . "</td>";
                echo "<td>" . $row['email'] . "</td>";
                echo "<td>" . $row['age'] . "</td>";
                echo "<td>" . $row['sex'] . "</td>";
                echo "</tr>"

            }
        echo "</table>";
    ?>

And the output coming is

"; while($row= mysql_fetch_array($res)) { echo ""; echo "" . $row['name'] . ""; echo "" . $row['email'] . ""; echo "" . $row['age'] . ""; echo "" . $row['sex'] . ""; echo "" } echo ""; ?>

Answer 1

mysqli_fetch_array not mysql_fetch_array and you're missing a ; after your echo "</tr>"
