CURL

[dreamwest]

I never done anything with curl before.

 

Can someone give me an example of how i can get a file from remote server and store it in local server

 

http://remote_site.com/files/video.mpg

to

http://local_site.com/temp/video.mpg

 

		
$remote = "http://remote_site.com/files/video.mpg";
$local = "http://local_site.com/temp/video.mpg";


$ch = curl_init($remote);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $output = curl_exec($ch);      
        curl_close($ch);
        echo $output;

 

Also can i use "http://" in the curl_int or do i have to remove slashes

Instead of echoing the file contents, save it with e.g. file_put_contents():

 

file_put_contents('/temp/video.mpg', $output);

Ive tried everything to get this to work.....i give up.

 

Onwards to scriptlance.............

How is it not working? Do you get any error messages? What version of PHP are you using?

[dreamwest]

I have no idea what im doing with this.

 

No errors, file wont go into local folder. Im using version 5 of php

 

Is there some error handler i can use to see if it transfered correctly

[thebadbad]

Firstly make sure the remote file is actually there. This code will output the remote file's header data:

 

<?php
$remote = 'URL to file here';
$ch = curl_init($remote);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 6.0; da; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10');
//return header only
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'HEAD');
$content = curl_exec($ch);
curl_close($ch);
echo $content;
?>

Let me see your output of that script, when you use the real URL.

[dreamwest]

echos out

 

HTTP/1.1 200 OK Date: Sat, 16 May 2009 11:52:43 GMT Server: Apache Last-Modified: Tue, 17 Feb 2009 11:00:33 GMT Accept-Ranges: bytes Content-Length: 1350504 Content-Type: text/plain

 

The file is video

Ok, seems fine. Try the script below then (I added some error handling):

 

<?php
$remote = 'URL to file here';
$ch = curl_init($remote);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 6.0; da; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$content = curl_exec($ch);
if ($content === false) {
echo 'cURL returned false.';
}
curl_close($ch);
$path = 'where/to/put/the/file.mpg';
$saved = file_put_contents($path, $content);
if ($saved === false) {
echo 'No data was stored.';
} else {
echo "$saved bytes were stored in $path";
}
?>

I see the file is ~ 1.35 MB in size, so it shouldn't be a memory/timeout problem. But to be sure, you can check the server's memory limit and max execution time with this:

 

<?php
echo 'Memory limit: ' . ini_get('memory_limit') . '<br />Max execution time: ' . ini_get('max_execution_time');
?>

thebadbad, script looks fine, but have you tried it without cURL ?

it sometimes works and its very simple

$remote = "http://remote_site.com/files/video.mpg";
$local = "path/to/storage/video.mpg";
file_put_contents($remote, $local);

 

Also remember you need write access to the folder your storeing the file to.!

Nope doesnt work. I need to transfer it anyways to convert it to another format

Hey it works!  Thanks

[thebadbad]

Great. Maybe the remote site checks the user agent string, to disallow requests from PHP scripts, where the default user agent string hasn't been changed from 'PHP'. And MacTechie is right (even though his script isn't); it could be coded simpler using file_get_contents():

 

<?php
ini_set('user_agent', 'Mozilla/5.0 (Windows; U; Windows NT 6.0; da; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10');
$url = 'http://example.com/video.mpg';
$path = 'where/to/put/the/file/' . basename($url); //remote filename is used
file_put_contents($path, file_get_contents($url));
?>

Just requires allow_url_fopen to be set to On.

Great just when i thought no one noticed lol, but i think everyone knew what i was getting at,

 

however if you want to convert the file, then surly your need to download it first then convert then remove old one!
