我的 PHP 代码出现一些语法错误，我无法解决

Question

我的 PHP 代码中出现语法错误，我无法解决。请看看这个并帮助我解决这个问题。 Here Is The Screenshot.

我附上了我在第 14 行遇到的错误的屏幕截图。

<?php
    $link = mysqli_connect('localhost','root','','satyam');
    if(isset($_POST['name']))
    {
        $name = $_POST['name'];
        $sql = "SELECT * FROM students WHERE name='".$name."'";
        $sql_run = mysqli_query($link,$sql);
        if($row=mysqli_fetch_array($sql_run))
        {
            $name = $row["name"];
            $roll = $row["roll"];
            $branch = $row["branch"];
            $address = $row["address"];
            echo 'Name: '.$name.' Roll: '.$roll.' Branch: '.$branch.' Address: '.$address';
        } else {
            echo "No Record Found";
        }
    }
?>

Answer 1

你在 :

的末尾有一个额外的 '

echo 'Name: '.$name.' Roll: '.$roll.' Branch: '.$branch.' Address: '.$address';

在$address

之后

Answer 2

您在下一行的末尾添加了一个额外的不必要的单引号 (')

echo 'Name: ' . $name . ' Roll: ' . $roll . ' Branch: ' . $branch . ' Address: ' . $address;

这段代码工作正常。

$link = mysqli_connect('localhost','root','','satyam');
if(isset($_POST['name'])) {
    $name    = $_POST['name'];
    $sql     = "SELECT * FROM students WHERE name='" . $name."'";
    $sql_run = mysqli_query($link,$sql);
    if($row = mysqli_fetch_array($sql_run)) {
        $name    = $row["name"];
        $roll    = $row["roll"];
        $branch  = $row["branch"];
        $address = $row["address"];
        echo 'Name: ' . $name . ' Roll: ' . $roll . ' Branch: ' . $branch . ' Address: ' . $address;
    } else {
        echo "No Record Found";
    }
}

Answer 3

请检查：

<?php
$link = mysqli_connect('localhost','root','','satyam');
if(isset($_POST['name']))
{
    $name = $_POST['name'];
    $sql = "SELECT * FROM students WHERE name='".$name."'";
    $sql_run = mysqli_query($link,$sql);
    if($row=mysqli_fetch_array($sql_run))
    {
        $name = $row["name"];
        $roll = $row["roll"];
        $branch = $row["branch"];
        $address = $row["address"];
        echo 'Name: '.$name.' Roll: '.$roll.' Branch: '.$branch.' Address: '.$address;
    } else {
        echo "No Record Found";
    }
}
?>

您在此行添加了一个额外的 ' :

echo 'Name: '.$name.' Roll: '.$roll.' Branch: '.$branch.' Address: '.$address;

Answer 4

这一行：

echo 'Name: '.$name.' Roll: '.$roll.' Branch: '.$branch.' Address: '.$address';

应该是：

echo 'Name: '.$name.' Roll: '.$roll.' Branch: '.$branch.' Address: '.$address;

Answer 5

删除第 14 行末尾的引号 (')（分号旁边的引号）。
