问题描述
我已经在php中尝试了一些用于用户注册的代码，这整个代码在本地服务器上工作正常但是当涉及到实时服务器时，每个PHP代码都会被执行但会话变量不会显示但是在本地服务器会话变量中传递并且正确显示
I have tried out some code in php for user registration this whole code works fine on local server but when it comes to live server every php code is getting executed but session variables are not displayed but in local server session variables are passed and displayed properly
DB_Function.php
public function storeUser($salutation, $fname, $lname, $dob, $mobile, $country, $state, $city, $pin){
try {
//$hash = md5($password);
$characters = '0123456789';
$uuid = '';
$random_string_length = 5;
for ($i = 0; $i < $random_string_length; $i++) {
$uuid .= $characters[rand(0, strlen($characters) - 1)];
}
$fullname = $fname . " " . $lname;
$vault_no = $salutation . "" . $country . "" . $pin . "" . $uuid;
$sql = "INSERT INTO users(salutation, fname, lname, fullname, dob, mobile, country, state, city, pin, unique_id, vault_no, created_at) VALUES ('$salutation', '$fname', '$lname', '$fullname', '$dob', '$mobile', '$country', '$state', '$city', '$pin', '$uuid', '$vault_no', NOW())";
$dbh = $this->db->prepare($sql);
/*execute the insert query in
get the user details return
*/
if($dbh->execute()){
// get user details
$sql = "SELECT * FROM users WHERE mobile = '$mobile' LIMIT 1";
$dbh = $this->db->prepare($sql);
$result = $dbh->execute();
$rows = $dbh->fetch();
$n = count($rows);
if($n){
return $rows;
}
}
}
catch (Exception $e) {
die('Error accessing database: ' . $e->getMessage());
}
return false;

推荐答案
在声明会话变量之前有空格。
You have space before declaring session variable.
<?php
session_start();
?>
注意之前的空格<？php。这将产生一个问题，所以只需删除它。
Note the space before <?php. This will create an issue so just remove it.
