在cPanel中我没有问题那些工作正常。但是在localhost中我遇到了很多错误。
Notice: Undefined variable: eroare in C:\xampp\htdocs\invo\install\index.php on line 68
Notice: Undefined variable: suc in C:\xampp\htdocs\invo\install\index.php on line 69
下面的index.php文件：
<?php
session_start();
if(isset($_POST['submit'])){
if($_POST['admin_user']=='' || $_POST['admin_pass']==''){
$eroare='Admin User/Pass Empty!';
}
if(!@mysql_connect($_POST['mysql_host'],$_POST['mysql_user'],$_POST['mysql_pass'])){
$eroare='MySQL Connection Failure';
}
if(!@mysql_select_db($_POST['mysql_db'])){
$eroare='MySQL Database Not Found!';
}
if(!$eroare){
$filename = 'sql.sql';
$templine = '';
$lines = @file($filename);
if(is_array($lines)){
foreach ($lines as $line_num => $line) {

$templine .= $line;
if (substr(trim($line), -1, 1) == ';') {
mysql_query($templine) or print('Error performing query \'<b>' . $templine . '</b>\': ' . mysql_error() . '<br /><br />');

我已经尝试过ioncube但是我认为我的本地主机中缺少一些东西，请告诉我如何在我的本地主机上运行它。这个undefine变量仅在localhost中声明，但在cpanel中声明为bot。

在文件开头初始化所有变量无论
$eroare = $suc = '';
请使用像PHPStorm这样的好IDE，然后点击Inspect Code工具查看弱错误和警告。
在服务器上，警告，错误已关闭。所以看到你的代码失败而没有发出任何警告的噩梦。所以请检查代码，然后只上传到实时服务器上。

首先，您在localhost中启用了更高级别的错误报告，而不是在远程计算机上启用。此通知级别错误不应该停止脚本执行。如果要修复错误，请在if语句中使用!empty($variable)表达式，如下所示：
<div class="content">
<?php if(!empty($eroare)){?><div class='error'><?php echo $eroare?></div><?php }?>
<?php if(!empty($suc)){?><div class='suc'><?php echo $suc?></div><?php }?>
<form action='' method='POST'>

试试这个脚本。
在session start（）函数之后添加这两行。
$eroare='';
$suc='';
答案 3 :(得分：0)
试试这个
if (empty($_POST['eroare'])) {
$eroare="";
} else {
$eroare=$_POST['eroare'];
}
