搬到這裏的文件是代碼:無法上傳和PHP

<html> 
<body> 

<form action="upload_file.php" method="post" 
enctype="multipart/form-data"> 
<label for="file">Filename:</label> 
<input type="file" name="file" id="file"><br> 
<input type="submit" name="submit" value="Submit"> 
</form> 

</body> 
</html> 

<?php 
$allowedExts = array("gif", "jpeg", "jpg", "png"); 
$extension = end(explode(".", $_FILES["file"]["name"])); 
if ((($_FILES["file"]["type"] == "image/gif") 
|| ($_FILES["file"]["type"] == "image/jpeg") 
|| ($_FILES["file"]["type"] == "image/jpg") 
|| ($_FILES["file"]["type"] == "image/pjpeg") 
|| ($_FILES["file"]["type"] == "image/x-png") 
|| ($_FILES["file"]["type"] == "image/png")) 
&& ($_FILES["file"]["size"] < 20000) 
&& in_array($extension, $allowedExts)) 
    { 
    if ($_FILES["file"]["error"] > 0) 
    { 
    echo "Return Code: " . $_FILES["file"]["error"] . "<br>"; 
    } 
    else 
    { 
    echo "Upload: " . $_FILES["file"]["name"] . "<br>"; 
    echo "Type: " . $_FILES["file"]["type"] . "<br>"; 
    echo "Size: " . ($_FILES["file"]["size"]/1024) . " kB<br>"; 
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>"; 

    if (file_exists("upload/" . $_FILES["file"]["name"])) 
     { 
     echo $_FILES["file"]["name"] . " already exists. "; 
     } 
    else 
     { 
     move_uploaded_file($_FILES["file"]["tmp_name"], 
     "upload/" . $_FILES["file"]["name"]); 
     echo "Stored in: " . "upload/" . $_FILES["file"]["name"]; 
     } 
    } 
    } 
else 
    { 
    echo "Invalid file"; 
    } 
?> 

當我試圖處理.png或任何其他圖像文件,我得到一個錯誤「無效文件」。

有多大,你要上傳的文件製作數百個可能的圖像修改?該腳本將其限制在20K以內。 – andrewsi

這是「upload_file.php」包含表單的文件名嗎? – Fallen
