我不是PHP程序员。有人问我为有问题的Web服务器提供帮助。我修复了所有内容，并更新PHP 5.4至5.6。除文件上传外，他的PHP程序上一切都很好。
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
此行上的错误：$img_info = getimagesize("uploads/temp/$filename");
if($_POST['fileselect'][0] != "")
$filename=$_POST['fileselect'][0];
else
$filename=$_POST['dragfile'];
if(strlen($filename) > 3){
$finalname=time(); //Set a unique filename by the UNIX time
//Convert to jpg if tiff
$img_info = getimagesize("uploads/temp/$filename");
if($img_info['mime'] == "image/tiff"){
$clearname=explode(".", "$filename")[0];
system("convert uploads/temp/"$filename"[0] uploads/temp/$clearname.jpg");
unlink("uploads/temp/$filename");
$filename=$clearname.".jpg";
}
问题可能来自php5.6中的新代码公式，任何想法如何解决？
更新2：文件上传部分...
form.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>
名称fileSelect []是否可能是问题？如何检查脚本是否在" upload.php"中？
upload.php的一部分
/* read the source image */
$source_image = imagecreatefromjpeg("$src");
$width = imagesx($source_image);
$height = imagesy($source_image);

上述代码的语法对于5.6来说是正确的，没有问题。
我也没有将权限视为问题，否则您会遇到"许可拒绝"错误。
因此，最有可能的是，您正在寻找的文件中不存在文件夹中的文件。
错误在这里： xhr.setRequestheader(" x_filename"，file.name(;
x-filename ...我认为这是apache更新问题。
感谢您的帮助。
