我知道这可能是一个明显的答案，但我为PHP新手它不是这样！Php代码符号在执行后转义（Sublime编辑器）
我正在用HTML编写一个带有Sublime内部文件的php代码，并且执行了代码更改后的文件。 <和>是用其逃逸字符编写的。帮助..请点击。
<?php
$username= trim($_POST['username']);
$pass= trim($_POST['pass']);
$userExist= trim($_POST['userExist']);
$passExist= trim($_POST['passExist']);
// print_r($username);
// print_r($pass);
$conn= mysqli_connect('localhost','neli','','yogies');
// if(!$conn){
// echo "No database";
// exit;
// }else {
// // echo "Done";
// // }
if(isset($username) && isset($pass)){
$usernameCheck = mysqli_query($conn, 'SELECT username FROM users WHERE username="'.$username.'"');
// print_r('SELECT username FROM users WHERE username="'.$username.'"');
if($usernameCheck && $usernameCheck->num_rows){
$check= 1;
} else {
$check=0;
}
}
if($check==0){
$userToEnter =$username;
$userToEnter = mysqli_real_escape_string($conn, $userToEnter);
$passToEnter = $pass;
$passToEnter = mysqli_real_escape_string($conn, $passToEnter);
$sql = 'INSERT INTO users (username,password) VALUES ("'.$userToEnter.'","'.$passToEnter.'")';
// print_r($sql);
if(mysqli_query($conn, $sql)){
session_start();
// print_r('here');
// print_r($_POST['url']);
$doc = new DOMDocument();
// html5 problems with tags
// libxml_use_internal_errors(true);
$doc->loadHTMLFile('header_nav.php');
// html5 problems with tags
// libxml_clear_errors();
$doc->getElementById('sign')->setAttribute('display','none');
$doc->getElementById('logout')->setAttribute('display','block');
$doc->saveHTMLFile('header_nav.php');
// header('Location: '.$_POST['url']);
}
}else{
print_r('Nope');
}
?>

请张贴代码。 –
我有在单独的文件中发送带隐藏的输入字段的网址，但它是做同样的事情。所以试图把一切都放在一个文件中 - 同样的东西... –
是你的文件扩展名.php吗？另外，不要使用'htmlspecialchars'，那将隐蔽'<'到HTML实体：？？''< –
