Using cURL (PHP's client URL extension) to download a file programmatically.

Hi All,

Here is a simple function using cURL to download a remote file. My goal here
was to access a remote wav file hosted on another server and import it into my
system.

Steps:
1. Enable cURL (see http://ca3.php.net/manual/en/ref.curl.php).
For windows: In order to enable this module on a Windows environment, you must copy
libeay32.dll and ssleay32.dll from the DLL folder of the PHP/Win32 binary
package to the SYSTEM folder of your Windows machine.
(Ex: C:\WINNT\SYSTEM32 or C:\WINDOWS\SYSTEM)

2. Uncomment the cURL extension in the php.ini file:
extension=php_curl.dll

Functionality:
1. Its a function and accepts three parameters (you can, of course, change this)
get_file1($file, $local_path, $newfilename)
$file : is the filename of the object to be retrieved
$local_path : is the local path to the directory to store the object
$newfilename : is the new file name on the local system

2. To use it:

<?php
$wav_file = get_file1($filename, $local_path, $newfilename);
?>

cURL returns true on success and false on failure.

The function:

<?php
function get_file1($file, $local_path, $newfilename)
{
$err_msg = '';
echo "<br>Attempting message download for $file<br>";
$out = fopen($newfilename, 'wb');
if ($out == FALSE){
print "File not opened<br>";
exit;
}

$ch = curl_init();

curl_setopt($ch, CURLOPT_FILE, $out);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL, $file);

curl_exec($ch);
echo "<br>Error is : ".curl_error ( $ch);

curl_close($ch);
//fclose($handle);

}//end function
?>

Happy coding.
