我的Php文件：

<?php
$con=mysqli_connect("localhost","prabha","prabha","cvsr");
// Check connection
if (mysqli_connect_errno()) {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

$result = mysqli_query($con,"SELECT * FROM details WHERE hallticket='$_GET["hallticket"]'");

while($row = mysqli_fetch_array($result)) {
  echo $row['name'] . " " . $row['hallticket'];
  echo "<br>";
}
?>

当我提交表格时，它显示为此错误

解析错误：解析错误，期待T_STRING' or T_VARIABLE＆＃39;或者`T_NUM_STRING＆＃39;在C：\ wamp \ www \第8行的新文件夹\ data.php

其实我正在尝试检索名称，如果我通过检查hallticket动态提交价值，请告诉我有什么问题

Answer 1

$hallticket = $_GET["hallticket"]; 
mysqli_real_escape_string($con,$hallticket); 
$result = mysqli_query($con,"SELECT * FROM details WHERE hallticket='$hallticket'");

通过动态接受其输入来检索数据
