I am Facing a small trouble..
I have a code which a ajax posts and returns a value from a page.
And the result is JSON , made by using

json_encode($response);

in PHP.
I converts the json to array using jQuery.parseJSON in jquery.. And it still works..

But sometimes it may happen any errors in my PHP page, So it will do not return a JSON code.
So the jquery shows error in jQuery.parseJSON..
Any Solution ??

What kind of errors? You can return errors and error messages through json just as well as results. – jeroen Oct 16 '14 at 18:52
@Harutyun : response is array, and i use jquery 1.11.0 – Shameel Kadannamanna Oct 16 '14 at 18:54
@jeroen : DB errors , and other errors – Shameel Kadannamanna Oct 16 '14 at 18:57
@ShameelKadannamanna As long as there are no syntax errors, you can catch almost all run-time errors and send the appropriate responses through json. – jeroen Oct 16 '14 at 19:00
ok , can you write a code to catch these errors – Shameel Kadannamanna Oct 16 '14 at 19:04
