升级PHP…然后。。。文件上载错误

我不是php程序员。有人向我询问有关web服务器问题的帮助。我修复了所有问题，并将PHP5.4更新为5.6。在他的php程序中，除了文件上传，一切都很好

消息：getimagesize（var/www/myserver/admin/uploads/temp/test.jpg）：无法打开流：没有这样的文件或目录

此行出错：

$img_info=getimagesize（“uploads/temp/$filename”）

问题可能来自php5.6中的新代码公式，您知道如何解决吗？
更新2：文件上载部分

php的一部分

<form method="post" class="form-horizontal">            
<input type="hidden" id="to_upload" name="to_upload" value="/upload.php">
        <input type="hidden" id="MAX_FILE_SIZE" name="MAX_FILE_SIZE" value="300000000" />
        <input type="hidden" id="id_produit" name="id_produit" value="<?php echo $this->mdl_inventory->form_value('idproduit'); ?>" />
            <div class="control-group">
                <label class="control-label">Nouveau (jpeg): </label>
                <div class="controls">
                    <input type="file" id="fileselect" name="fileselect[]">
                </div>
            </div>


上述代码的语法对于5.6是正确的，没有问题。

我不认为权限也是一个问题，否则您会得到一个“权限被拒绝”错误


因此，很可能您正在查找的文件不在文件夹中。
错误在这里：
setRequestHeader（“X_文件名”，file.name）

X文件名。。。我认为这是APACHE更新的问题

谢谢你的帮助。
我忘了说，php.ini是一样的，没有变化。使用完整的根路径
/home/blabla/blabla/
。你检查过文件是否存在吗？var/www/myserver/admin/uploads/temp/test。jpg@RiggsFolly这是自PHP5.4以来的有效语法，请参见类似权限问题的内容。尝试对相应的文件夹和文件设置适当的权限
