How to read web services output with PHP

[Kud]

Hello,

I have a successful web service running from the tutorial provided by labview. The data does display when accessing the local URL with no issues. My problem is when I try to read the data using php I get a blank page. I have tried XML and json output. The json output stalls the page from loading and eventually I get a error 500 in IE. Any help would be greatly appreciated.

Well I think I figured it out. If I had paid a little more attention I would have noticed I needed to write a separate vi as the "web client" to communicate with the web service instead of actually browsing directly to the web service it's self. Any added help is greatly appreciated.

Yeah I don't get it. It's to the point where I am pulling my hair out. I do not understand why I can not read my web services output with php. I have tried reading the URL with all the different methods php offers for reading files/URLs. I do not know what else to try. It seems like I am so close to getting this to work and I feel like I am missing something. The sad thing is, this post will be lost in the thousands of pages of other posts and will never be answered.

Hello Kud,

Can you verify that you see data when using HTTP Get?  You can find this function from Data Communication >> Protocol >> HTTP Client.

For example:
 

If so, this really is a PHP issue rather than a National Instruments/LabVIEW.  Take a look at this for more help.

Thanks,
