copy a file from remote with cUrl

Hello,

I need to copy a file without using the php function "copy".

I got this example sometime before from Nick:

Code:

<?php
$ch = curl_init("http://www.bergtoys.info/");
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$curl_ret = curl_exec($ch);

$data = curl_getinfo($ch);


curl_close($ch);

where $data is the data I collected via curl, now I need to save this data into a file (image) on the server, do I need to use a fopen function now?

Yes, but in the code you posted, the contents of the file are stored in the $curl_ret variable.

The $data has the info about the session (headers, etc)

OK

do you have an example how to handle error's with curl (since there are no booleans possible like "if (!copy(..."

I check if the strlen($curl_ret) is bigger than 0 and the response header (right now is in the $data)

what about this function?

Code:

<?php
function copy_with_curl($url) {
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$curl_data = curl_exec($ch);
if (curl_errno($ch) == 0) {
if ($fd = @fopen($this->thumbnail_path, "wb")) {
fwrite($fd, $curl_data);
fclose($fd);
$err = true;
} else {
$err = true;
}
} else {
$err = true;
}
curl_close($ch);
return $err;
}

Nice, but you have a small error

The replacement should be this :

Code:

<?php
function copy_with_curl($url) {
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$curl_data = curl_exec($ch);
if (curl_errno($ch) == 0) {
if ($fd = @fopen($this->thumbnail_path, "wb")) {
fwrite($fd, $curl_data);
fclose($fd);
$err = false;
} else {
$err = true;
}
} else {
$err = true;
}
curl_close($ch);
return $err;
}

I am not sure about this, but you can check it :

Code:

<?php
if ( !extension_loaded('curl') )
     echo 'Problem....';

is there only a curl extension?
(then I'm able to check this via phpinfo())

yes, curl is available on all shared hosts I'm using (6 diff. configurations)

and I learned that there are much more configuration settings then with functions like fopen... COOL!

Of course. Actually curl is an 'interface' to fopen, and it uses fopen to work....

strange is that the setting "allow_url_fopen" is not blokking here...

This is propably because curl is using fopen from the Zend engine level (php.ini restrictions are not a problem there)

Yes that's possible...
