PHP T_Public語法錯誤？

Question

我想不出什麼導致這個錯誤：

Parse error: syntax error, unexpected T_PUBLIC

它說的錯誤是在此代碼(public function upload($uid = 'public')的第二行存在的。

//--> Uploads the file 
public function upload($uid = 'public') 
{ 

//Get file details 
if(isset($_GET['ajax'])) 
{ 
if(!$_SERVER['HTTP_X_FILE_SIZE'] > 0) return false; 

$filename = strip_tags($_SERVER['HTTP_X_FILE_NAME']); 
$file_type = $_SERVER['HTTP_X_FILE_TYPE']; 
$size = round($_SERVER['HTTP_X_FILE_SIZE']/1000, 3); 
} 
else 
{ 
if($_FILES["files"]["error"] > 0 or empty($_FILES)) return false; 

$filename = strip_tags($_FILES['files']['name']); 
$file_type = $_FILES['files']['type']; 
$size = round($_FILES['files']['size']/1000, 3); 
} 

//FF null type fix 
if($file_type == null || strlen($file_type) == 0) $file_type = "unknown"; 

//Reduce filename to < 255 char 
if(strlen($filename) > 255) 
{ 
$filename = urldecode($filename); 
$filename = substr($filename, 0, 36) . '--.' . pathinfo($filename, PATHINFO_EXTENSION); 
$filename = urlencode($filename); 
} 

//Check file size 
if($size > (maxFileSize/1000)) 
{ 
$this->errorMessage = "file too large"; 
return false; 
} 

//Check file type 
if(limitFileTypes and !in_array($file_type, explode(',', allowedFileTypes))) 
{ 
$this->errorMessage = "file type not allowed";

您正在定義功能public。

public是Object Orieneted Programming的關鍵字。

但是，根據您的代碼，沒有定義類，因此，沒有使用public關鍵字。

只需刪除public關鍵字。

更正代碼：

function upload($uid = 'public')
