I have a PHP file which generates a JSON document.

I\'ve set the header as follows but am still getting an error.

header(\'Access-Control-Al         


        

Answer 1

It doesn't look there is anything wrong with the code that sets the header, but you may want to check if the header is actually being set. Use curl -i http://yourapp to check the response headers being sent to debug it. Alternatively, you can use the network tab in Google Chrome's web inspector, or the Network tool in Firefox's Web Developer tools.
