无法上传超过1MB的文件 - PHP webserver

我目前正在使用我拥有的网络服务器做一些噩梦。我已经搜索了我能找到的每个Stack Overflow页面,但仍然没有成功。

我有一个本地运行的网络服务器,我会首先测试这些设置,一切正常,但每当我将相同的设置应用到我的主服务器时,都没有运气。

我只是通过使用一个简单的html页面和php页面来处理请求,直接回到基础,这仍然失败,超过1MB。

供参考,这是我的html脚本:

<!DOCTYPE html>
    <html>
    <body>

    <form action="test.php" method="post" enctype="multipart/form-data">
        Select image to upload:
        <input type="file" name="fileToUpload" id="fileToUpload">
        <input type="submit" value="Upload Image" name="submit">
    </form>

    </body>
</html>

这是我处理请求的test.php页面:

<?php
$target_dir = "";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);

// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 8000000) { //8mb
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
?>

这只是来自w3学校的基本php图片上传脚本 - 这就是这个问题让我减少了!

我尝试过:

  • 编辑php.ini文件,然后重新启动apache
  • 更改html表单,使其在表单标题中包含enctype =“multipart / form-data”
  • 将.htaccess添加到文件
  • 的根www / html文件夹中
  • 更改上传脚本的位,指定允许的最大图像大小:

我得到的错误是:

Warning: getimagesize(): Filename cannot be empty in /var/www/html/test.php on line 8
File is not an image.Sorry, your file was not uploaded.

任何人都可以帮助我吗?我也尝试过调试禁用mod_security,但我甚至无法在我的apache2服务器上找到它。

非常感谢。

您可以通过以下两种方式更改上传限制

i)在php.ini

中更改upload_max_filesize的值

ii)使用ini_set(&#34; upload_max_filesize&#34;,&#34; 30M&#34;);
