the filename .xls is not readable - php

Question

I want to download file .xls and then upload it to database oracle. but I am getting an error "the filename .xls is not readable".
Below is my script:
<? require_once (dirname(__FILE__)."/upload/upBc.php");
if(!empty($_FILES["file"])){
echo $file = $_FILES["file"];
}else{
/*$file = "/opt/lampp/htdocs/avar/pp/ccr/test.xls";*/
$file = '/www.upload.com/pm_ms/test.xls';
/* $file = "website_data_". date('ymd').".xls";*/
}
$upload = new upload();
$upload->setFile($file);
$upload->getFileType();
$upload->getFileName();
$upload->getFileDir();
$upload->readDataTbc();
$dataD = array ();
$dataD = $upload->getDataTbc();
echo "<table border = 1>";
for($i=1;$i < count($dataD);$i++){
echo "<tr>";
for($j=0;$j < $upload->getHSize();$j++){
echo " <td>".$dataD[$i][$j]."</td>";
}
echo"</tr>";
}
echo"</table>";
echo"data length=". count($dataD);
$upload->commitDataTbc();
?>
If I use $file = "/opt/lampp/htdocs/avar/pp/ccr/test.xls";. in my program it works
but if I use $file = '/www.upload.com/pm_ms/test.xls';. I get the error THE FILENAME test.xls is Not Readable

Answer 1

That's probably because /www.upload.com/ doesn't exist on your server.
Do you know the actual path to the file? By prefixing the URI with / this makes it absolute, which means that it's trying to read literally from /www.upload.com on your server. If you're looking to make this relative you could try ./upload.com/ or simply upload.com/ as the path prefix.
If you are however trying to load it from the website upload.com (instead of a folder from your server) you have two options:
(If Supported) Set the filename as a URL ie. $file = 'http://www.upload.com/pm_ms/test.xls';
Download the file and then open it locally.
For #2:
$file = 'test.xls';
$ctnts = file_get_contents('http://www.upload.com/pm_ms/test.xls');
file_put_contents($file, $ctnts);
