### php使用move\_uploaded\_file上传文件报错failed to open stream: Invalid argument in 解决方案 ###

先报错failed to open stream: Invalid argument

然后写入失败。

文档编码使用UTF-8

因为用英文名称文件上传，一切正常

代码如下：

<?php
    /* UploadiFive Copyright (c) 2012 Reactive Apps, Ronnie Garcia */
    
    // Set the uplaod directory
    $uploadDir = 'uploadify/uploads/';
    
    // Set the allowed file extensions
    $fileTypes = array('jpg', 'jpeg', 'gif', 'png'); // Allowed file extensions
    
    $verifyToken = md5('unique_salt' . $_POST['timestamp']);
    
    if (!empty($_FILES) && $_POST['token'] == $verifyToken) { 
        $tempFile = $_FILES['Filedata']['tmp_name'];
        $uploadDir = $_SERVER['DOCUMENT_ROOT'] . $uploadDir;
        $targetFile = $uploadDir . $_FILES['Filedata']['name'];
    
    	//关键性代码 转码
        if (function_exists("iconv"))     { 
            $targetFile=iconv("UTF-8","GBK",$targetFile);
        }
    
    
        echo $targetFile;
        // Validate the filetype
        $fileParts = pathinfo($_FILES['Filedata']['name']);
        if (in_array(strtolower($fileParts['extension']), $fileTypes)) { 
    
            // Save the file
            move_uploaded_file($tempFile, $targetFile);
            echo 1;
    
        } else { 
    
            // The file type wasn't allowed
            echo 'Invalid file type.';
    
        }
    }
    ?>
