php isn't giving any error in output

Question

I have apache2 installed on my PC. And php5 and all the stuffs. The php is also running fine. I checked commands INSERT INTO myTable etc and it's working fine. I've phpMyAdmin installed and it's also working fine. The problem is that I'm not getting any error when there is actually error. for e.g. PHP :

<?php
  <?php
  $umair = 1

  echo $umair;
  echo 'asdf';
?>

This code isn't outputting anything. As you can see there is error of semicolon here and the PHP must show some error. And if I put the semicolon then the PHP runs as usual and get the output 1asdf

Set your php.ini settings to display errors :

- error_reporting to E_ALL
- display_errors to on

(those are developement environment settings of course ; more about error_reporting levels here)

You can find your php.ini location using phpinfo() in a PHP script.

EDIT In case it isn't that, try to execute a valid script, and tell us if it runs correctly. If it doesn't, it probably means that your php module installation failed somehow.

EDIT 2 Restarting Apache will be necessary after editing such parameters.

I'm not inclined to believe, that error reporting can salvage the problem – samayo Jul 14 '13 at 13:10
It most probably can. – Cthulhu Jul 14 '13 at 13:10
In a debug situation, I suggest setting these parameters to a value that will display as much as possible. There wouldn't be any need of displaying errors with a 0 reporting level on the server, for instance. – John WH Smith Jul 14 '13 at 13:11
@Cthulhu The errors shown by OP, are should pretty much be displayed, dispite the error reporting directives – samayo Jul 14 '13 at 13:12
Well let's see how it turns out. – Cthulhu Jul 14 '13 at 13:15
Could you edit your post and paste the last lines of your Apache logs ? (error.log and access.log) No output could be an incomplete answer from the server. – John WH Smith Jul 14 '13 at 13:28
Oh Actually it worked. I just needed to restart the apache server. Thanks :) – omerjerk Jul 14 '13 at 13:29

You can try to show the errors for the current file that you're working on right now by adding

error_reporting(E_ALL);

and try to check this

The problem is that the missing ";" is a parser error - and parsing is done before execution. PHP will simply not even start executing an invalid script - so you don't see anything.

Try to include this script in another script and run that - then you will get a clear error-msg!

Here's more on that topic and also my script to do this: How to get useful error messages in PHP?
