don't go making changes to your original post http://stackoverflow.com/revisions/34581037/1 without stating that there was an edit / code change that you tried. The person who answered may get downvoted because of it, where people will tell/ask themselves: *"He's got them like that, so why the answer?"*. You MUST always mark code that you tried/changed underneath your original question/code and stating that that was what you tried. Besides, you still missed some and is why your code is still failing. — Funk Forty Niner, Jan 03 '16 at 20:18
Oh and a blank page, usually means syntax errors, which you have. So, when learning PHP, check for those. http://php.net/manual/en/function.error-reporting.php which you're not and should. And is the grounds on which your question was closed as a duplicate. — Funk Forty Niner, Jan 03 '16 at 20:24
I also performed a rollback to your original question/code http://stackoverflow.com/revisions/34581037/1, since you did not state your *Stealth edit* http://stackoverflow.com/revisions/34581037/2 as being what you changed given from an answer given. — Funk Forty Niner, Jan 03 '16 at 20:29

It should be $_POST and not $_post. $_POST is one of PHP's superglobals and must be in all caps. $_post will be treated as a local variable. (ref)

can you elaborate on that? There's a ***specific*** reason as to *why* it should be. Edit: yep, that's it ;-) – Funk Forty Niner Jan 03 '16 at 20:09
nothing happend same blank out put page with $_POST @patric lee – router Jan 03 '16 at 20:11
Yes, I should have elaborated on that. Just expanded the answer. @router: Did you change all four uses of `$_post` to `$_POST`? Also, is this the content of `try.php` where the form is being posted? – Patrick Lee Jan 03 '16 at 20:14
$_POST is a super global variable of php containa form input in an array.. if u use $_post it seems to be simple variable but I think thia variable is undefined – devpro Jan 03 '16 at 20:16
i have attached photo also , yes i changed it to $_POST and form is being posted on same try page its single page coding – router Jan 03 '16 at 20:16
Than chk print_r($_POST); WHAT U GETTING @router – devpro Jan 03 '16 at 20:17
@devpro what will be the solution then – router Jan 03 '16 at 20:18
@router: We're not sure about the solution yet. @devpro is suggesting `print_r($_POST)` in order to gather more information about the problem. – Patrick Lee Jan 03 '16 at 20:19
Ist of all chk what r u getting... use print_r($_POST); U WILL GET THE IDEA – devpro Jan 03 '16 at 20:19
echo or print are showing nothing i get blank output page with no error – router Jan 03 '16 at 20:20
Look at their edit http://stackoverflow.com/posts/34581037/revisions and look at [my comment to them...](http://stackoverflow.com/questions/34581037/php-no-error-but-blank-output-page#comment56907326_34581037) – Funk Forty Niner Jan 03 '16 at 20:21

Based on your edited code, you still have two uses of `$_post` that need to be changed to `$_POST`. – Patrick Lee Jan 03 '16 at 20:21
WHY DON YOU try it on your local host – router Jan 03 '16 at 20:21

@router *"its a simple program and you expert are unable to get it ...... OMG"* - actually, yes we are. – Funk Forty Niner Jan 03 '16 at 20:21
*"WHY DON YOU try it on your local host – router"* - No need to, we already know why your code is *still* failing. @router – Funk Forty Niner Jan 03 '16 at 20:22

And insulting the people who are trying to help you is not the best move. As previously stated, make sure every use of `$_post` is changed to `$_POST`. – Patrick Lee Jan 03 '16 at 20:24
@fred-ii love u man.... :) – devpro Jan 03 '16 at 20:24
thanks @PatrickLee i have done with it you are genius – router Jan 03 '16 at 20:24

@router: we all told u to chk duplicate link. And if u cant than try this........ if(count($_POST) > 0){print_r($_POST); exit;} try it and share the result... – devpro Jan 03 '16 at 20:27

@router: Not sure about the genius part, but glad it's working. In the future, please read answers and comments carefully and make sure you follow the suggestions to the letter. – Patrick Lee Jan 03 '16 at 20:31
its done. it was error of $POST instead of $post @PatrickLee was right – router Jan 03 '16 at 20:31
