问题描述

<?php
$conn = mysqli_connect('localhost','root','','khazar');
if(!$conn){
	die("Connection failed!!!").mysqli_error();
}
else{
	echo "Connected succesfully";
}

$sql = "SELECT * FROM students";
$result = mysqli_query($conn,$sql);
if(!$result){
	die("table connection problem!");

// listing all datas from table
echo "<h2>List of al records: ".mysqli_num_rows($result)."</h2>";
echo "<table>";
//if(mysqli_num_rows($result)>0){
	while ($row = mysqli_fetch_assoc($result)) {
		echo $row['id']." | ".$row['name']." | ".$row['username']." | ".$row['password']."<br>";
		?>

		<form method="post" action="$_SERVER['PHP_SELF']">

		<a href="f.php? id=<?php echo $row['id']?>">EDIT</a>
		<a href="f.php? id=<?php echo $row['id']?>">UPDATE</a>

<!--	}   -->
}
<?php
if(isset($_GET['id'])){
	$id = $_GET['id'];
	$sql2 = "DELETE FROM students WHERE id=".$id;

	header("Location:".$_SERVER['PHP_SELF']);
}
mysqli_close($conn);

我尝试过：



错误是：



解析错误：语法错误，C：\ xampp \ htdocs \\ .f中的文件意外结束。第39行的PHP



i改变了很多东西并尝试了，但这个错误总是存在。

请说，这个错误是什么意思？实际错误是什么？

What I have tried:

error is:

Parse error: syntax error, unexpected end of file in C:\xampp\htdocs\f.php on line 39

i changed many things and tried,but this error always exist.
please,say,what does this error mean? and what actually error is ?

推荐答案

conn = mysqli_connect（'localhost'，'root'，''，'khazar'）;
if（！

conn = mysqli_connect('localhost','root','','khazar'); if(!

conn）{
die（Connection failed !!!）。mysqli_error（）;
}
else {
echo成功连接;
}

conn){ die("Connection failed!!!").mysqli_error(); } else{ echo "Connected succesfully"; }

sql =SELECT * FROM students;

sql = "SELECT * FROM students";
