Re: curl Question

Here's the scoop on curl. 1st, if you want to use the built in curl function you have to compile php with curl personally i use curl as a standalone and exec() it out of php, not functions. to speak with an https server (ssl) you must have a protocol which can do so. php cannot do it on it's own. sure it can handle getting unencrypted web pages, but getting pages through ssl in cannot. actually, i take that back, php can talk with with an ssl server (sql_dump i believe to read what the server returns) unfortunately it can only be accesed through a url, using the GET function if you are sending variables. your broswer has built in functions to POST information to the ssl server, but that has nothing to do with the php script itself sending ssl data. so, to answer your question. if you want to POST information to a ssl web server you need to use curl, or another application capable of posting via ssl. when posting to a credit card approval sever (transaction server) most if not all require you to use the post method. i beleive the php code exchange has a couple classes on using curl to do this. if you just need to request data from another site, and the get methodis appropriate the solution is much simpler. you may want to create a new message addressing GET via SSL, as I don't have the entire answer, i just know it can be done. jason > > From: Sonia Tsui <Stsui@villamontage.com> > > Date: Wed, 3 Jan 2001 16:36:20 -0800 > > To: "'php-general@lists.php.net'" <php-general@lists.php.net> > > Subject: [PHP] curl Question > > > > Hi, > > > > Has anyone ever used libcurl with PHP? libcurl is a library that allows you > > to connect and communicate to many different types of servers with many > > different types of protocols (eg httpds).
