Downloading a remote file with PHP

[cagagnon]

Hey guys. I need to download a file to my server given a URL but it isn't working. For some reason it isn't downloading the whole file, it is only getting part. Here is my code:

<?php 

/* Tutorial by AwesomePHP.com -> www.AwesomePHP.com */ 
/* Function: download remote file */ 
/* Parameters: $url -> to download | $dir -> where to store file | 
    $file_name -> store file as this name - if null, use default*/ 

function downloadRemoteFile($url,$dir,$file_name = NULL){ 
    if($file_name == NULL){ $file_name = basename($url);} 
    $url_stuff = parse_url($url); 
    $port = isset($url_stuff['port']) ? $url_stuff['port'] : 80; 

$fp = fsockopen($url_stuff['host'], $port); 
if(!$fp){ return false;} 

$query  = 'GET ' . $url_stuff['path'] . " HTTP/1.0\n"; 
$query .= 'Host: ' . $url_stuff['host']; 
$query .= "\n\n"; 

fwrite($fp, $query); 

while ($tmp = fread($fp, 8192))   { 
    $buffer .= $tmp; 
} 

preg_match('/Content-Length: ([0-9]+)/', $buffer, $parts); 
$file_binary = substr($buffer, - $parts[1]); 
if($file_name == NULL){ 
    $temp = explode(".",$url); 
    $file_name = $temp[count($temp)-1]; 
} 
$file_open = fopen($dir . "/" . $file_name,'w'); 
if(!$file_open){ return false;} 
fwrite($file_open,$file_binary); 
fclose($file_open); 
return true; 
}  

?>

I found it from Here

Like I said, I am only getting about 4 Kb of the files I am testing with:
Test Link 1
Test Link 2
Test Link 3
Test Link 4
Test Link 5

Thanks in advance!

I'd start by replacing this:

function downloadRemoteFile($url,$dir,$file_name = NULL){ 
    if($file_name == NULL){ $file_name = basename($url);} 
    $url_stuff = parse_url($url); 
    $port = isset($url_stuff['port']) ? $url_stuff['port'] : 80; 

$fp = fsockopen($url_stuff['host'], $port); 
if(!$fp){ return false;} 

$query  = 'GET ' . $url_stuff['path'] . " HTTP/1.0\n"; 
$query .= 'Host: ' . $url_stuff['host']; 
$query .= "\n\n"; 

fwrite($fp, $query); 

while ($tmp = fread($fp, 8192))   { 
    $buffer .= $tmp; 
} 

preg_match('/Content-Length: ([0-9]+)/', $buffer, $parts); 
$file_binary = substr($buffer, - $parts[1]); 
if($file_name == NULL){ 
    $temp = explode(".",$url); 
    $file_name = $temp[count($temp)-1]; 
} 
$file_open = fopen($dir . "/" . $file_name,'w'); 
if(!$file_open){ return false;} 
fwrite($file_open,$file_binary); 
fclose($file_open); 
return true; 
}

with this:

function downloadRemoteFile($url,$dir,$file_name = NULL){ 
    return (bool)file_put_contents("$dir/$file_name", file_get_contents($url));
}

} 

I tried that but it still looks like I'm only getting about 4 KB of a 139 KB file. Is there any way to test why it isn't getting the whole file? Like can I somehow get errors if there are any?

Thanks for the help

Do you have the PHP directives display_errors set to On and error_reporting set to E_ALL?

Yes, I do. But I don't see anything.

EDIT: The file I want to download is an apk (android package file) if that matters.

[bradgrafelman]

Can you try downloading a file from a different server?

[cagagnon]

It looks like it is not working for different types of files either. I tried it for an image (.jpg) and it still didn't work. Is there anything in my php.ini which may be blocking it?

EDIT:
I also tried:

    if(!@copy($_url,$_dir))
	{
    	$errors= error_get_last();
    	echo "COPY ERROR: ".$errors['type'];
    	echo "<br />\n".$errors['message'];
	} else {
    	echo "File copied from remote!";
	}

But I got the following error:

copy(): failed to open stream: HTTP request failed!

This is all of the error message? Does it not tell you the reason why it failed? perhaps something like

copy(http://example.com/no_such_file.ext) [function.copy]: failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found
