RE: [PHP] Fopen and streams

Ok, so, I solved the problem, but haven't necessarily figured it out. I was using fopen() on a unique device, and getting a stream error. Rewrote the func using the basic example for fsockopen. I can now get the data I need without the errors, but now, a new question: If indeed there was some sort of incompatiblity between the scheme that fopen() was using to get at my device, where do I start to find out what kind of scheme I could be using? Do I hunt down the manufacturer and get some tech papers on their device? Or could I / should I use something like nmap, if that would work at all. It just now occurred to me, and I haven't tried it yet. Secondly, where is a good place to read on the standards and formats used by these different schemes. In the fsockopen() func, I made some writes to 'GET / ' and 'HTTP 1.1' etc... After reading the script, I understand what these imply, but not the importance, also, what other commmands are available to me. Does that all make sense? I guess more simply put: How do I know what commands are availble to me in the different protocals. HTTP, FTP, UDP, etc...what if I wanted to get at the data through straight TCP, is that possible? Lastly, where should I go to read up on how to make my scripts run faster? I haven't written anything to large, but I'm generalyy paranoid about overhead, esp in areas I probably don't need to be worried about. Silly questions I suppose, like, is it more efficient to echo one long string or echo parts of it on separate lines. The latter is easier when creating tables and such, because I can comment out individual lines to hunt down bugs. But does it make a difference in the runtime of the script? Etc....

Having some trouble with a line that used to work, but doesn't now. $pg = fopen("http://$ip/mypage", "r"); Gets me: Warning: fopen(http://10.1.1.233/mypage): failed to open stream: HTTP request failed! And then it spits out the data from that page anyways. What's going on here? This was working on my other box a few days ago. And I've tried it with and without the variable for the ip address/url. --Stryder
