当我尝试在表“userstbl”中插入一行时，我在一个简单的 PHP 页面中出现以下错误

错误：

您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以获取在 '\'userstbl\' (\'usr_name\', \'usr_pwd\', \'usr_fname\', \'usr_lname\') 附近使用的正确语法。 \' 在第 1 行

这是代码：

$con = mysqli_connect("localhost","root","","test_sms"); 
if (mysqli_connect_errno())
{
    echo "Failed to connect:" . mysqli_connect_error();
    }
$value = "INSERT INTO 'userstbl' ('usr_name', 'usr_pwd', 'usr_fname', 'usr_lname') VALUES ('Aftab','xyz','Aftab','Hussain')";
$sqlin = mysql_prep($value);
if (!mysqli_query($con, $sqlin)){
    die ('Error: ' . mysqli_error($con));
    }
$sqlot = "SELECT * FROM 'usertbl'";
$sqlo = mysql_prep($sqlot);
$sqlout = mysqli_query($con , $sqlo);
echo "<table border='1'><tr><th>ID</th><th>Username</th><th>Password</th><th>First Name</th><th>Last Name</th></tr>";
while ($row = mysqli_fetch_array($sqlout));
{
    echo "<tr>";
    echo "<td>" . $row['usr_id'] . "</td>";
    echo "<td>" . $row['usr_name'] . "</td>";
    echo "<td>" . $row['usr_pwd'] . "</td>";
    echo "<td>" . $row['usr_fname'] . "</td>";
    echo "<td>" . $row['usr_lname'] . "</td>";
    echo "</tr>";
    }

mysqli_close($con);
?>

如果要转义列名和表名，请使用反引号，而不是引号

INSERT INTO `userstbl` (`usr_name`, usr_pwd, usr_fname, usr_lname)
VALUES ('Aftab', 'xyz', 'Aftab', 'Hussain')

尝试

$con = mysqli_connect("localhost","root","","test_sms"); 
if (mysqli_connect_errno())
{
    echo "Failed to connect:" . mysqli_connect_error();
    }
$value = "INSERT INTO userstbl (usr_name, usr_pwd, usr_fname, usr_lname) VALUES ('Aftab','xyz','Aftab','Hussain')";
$sqlin = mysql_prep($value);
if (!mysqli_query($con, $sqlin)){
    die ('Error: ' . mysqli_error($con));
    }
$sqlot = "SELECT * FROM usertbl";
$sqlo = mysql_prep($sqlot);
$sqlout = mysqli_query($con , $sqlo);
echo "<table border='1'><tr><th>ID</th><th>Username</th><th>Password</th><th>First Name</th><th>Last Name</th></tr>";
while ($row = mysqli_fetch_array($sqlout));
{
    echo "<tr>";
    echo "<td>" . $row['usr_id'] . "</td>";
    echo "<td>" . $row['usr_name'] . "</td>";
    echo "<td>" . $row['usr_pwd'] . "</td>";
    echo "<td>" . $row['usr_fname'] . "</td>";
    echo "<td>" . $row['usr_lname'] . "</td>";
    echo "</tr>";
    }

mysqli_close($con);
?>
