完成所有步骤后,PHP文件上载无法正常工作。 (我认为)

这是我的背景:

我正在使用运行Apache和LAMP的Amazon EC2 Linux实例。

我试图上传PHP图片。

我从W3Schools获得了代码。

我尝试以Superuser (su)身份登录,并将上传文件夹(/var/www/html/photo/backend/images/uploads)的权限更改为chmod 755

我已尝试投放print_r($_FILES);并获取Array ( )

我已在php.ini中更改了这些内容:

  • file_uploads设为on
  • max_execution_time设置为300(秒)
  • max_file_size设为100(MB)

我已经尝试过并搜索了我能想到的所有内容,但我仍然无法弄清楚为什么我的图片无法上传。对不起,如果这很广泛,但我真的不知道问题是什么。

问题:

图片无法上传(不知道为什么,我想我已经按照所有步骤进行了操作,见上文)

这是我的代码:



<?php
$target_dir = "/backend/images/uploads";
$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 $uploadOk is set to 0 by an error
if ($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( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
		print_r($_FILES);
    }
}
?>
&#13;
<!DOCTYPE html>
<html>
<body>

<form action="/backend/images/upload.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>
