I would like to know if there is a way to request data from a web services for example http://glkev.net.innerhost.com/glkev_ws/Currencyws.asmx using php without java ?

If you know the web services API, you just send your request. It shouldn't matter whether you're using Java, PHP, Python, even VB or even Telnet to generate your request -- most web services accept an HTTP POST message consisting of XML code which is used to perform some kind of action. There are two things you can do -- either use the cURL functions (your PHP binary must be compiled with cURL enabled to do this), which give you an advanced set of URL accesses, or open a socket to the remote machine with the web service and send a stream of POST data that way. You can use Rasmus Lerdorf's "postToHost" function (this may as well just become a PHP function, it gets referenced so much), which I have appended to this message. Either way, just generate your XML string and fire it at the remote machine. You will need to write code to handle the response, obviously. # =============================================================== # PostToHost($host, $path, $data_to_send) # --------------------------------------------------------------- # "It is a trivial little function." # -Rasmus # =============================================================== function PostToHost($host, $path, $data_to_send) { $fp = fsockopen($host,80); fputs($fp, "POST $path HTTP/1.0\n"); fputs($fp, "Host: $host\n"); fputs($fp, "Content-type: application/x-www-form-urlencoded\n"); fputs($fp, "Content-length: " . strlen($data_to_send) . "\n"); fputs($fp, "Connection: close\n\n"); fputs($fp, $data_to_send); while(!feof($fp)) { echo fgets($fp, 128); } fclose($fp); } Erik ---- Erik Price Web Developer Temp Media Lab, H.H.
