Using sockets in PHP : Get articles from Usenet
http://www.phpbuilder.net/columns/armel20010427.php3
PHP can open sockets on remote or local hosts. Here is a hands-on example of using such a socket: getting connected to a Usenet News Server, talking to this server, and downloading some articles for a precise newsgroup.
Opening a socket in PHP
Sockets are opened using fsockopen(). This function is both available in PHP3 and PHP4. [...]

Custom Form Helpers in Solar
Another thing that Solar makes easy is the creation of custom form helpers. These can be anything outside of the usual input types (like text, checkbox, textarea, etc) and can be used to make helpful, more complex inputs for your app.
In a previous post, I worked some with the Solar_Form class to create a login [...]
Being Binary in SOAP
Well, it might not be the best way to do it, but here’s a way I found to send binary data via PHP’s SOAP extension from one place to another:
Server:
?View Code PHPfunction recieveFile($data){
$data=base64_decode($data);
$path=’/my/file/path/img_out.gif’;
$fp=fopen($path,’w+’);
if($fp){ fwrite($fp,$data); fclose($fp); }
return strlen($data).’written’;
}
$input = file_get_contents(”php://input”);
$server = new SoapServer(’http://[my url here]/binary.wsdl’,array(’encoding’=>’ISO-8859-1′));
$server->addFunction(’recieveFile’);
$server->handle();
and the Client:
?View Code PHPini_set("soap.wsdl_cache_enabled", "0");
//send binary data
$client=new SoapClient(’http://[my url here]/binary.wsdl’,array(’encoding’=>’ISO-8859-1′));
$data=file_get_contents(’/my/file/path/img_to_send.gif’);
$ret=$client->recieveFile(base64_encode($data));
print_r($ret);
[/code]
It’s pretty [...]

Raises the efficiency in PHP mode through the factory pattern [reprint]
