How can I get php errors reported?

Question

Currently installed php version 5.3.10. It is not reporting any kind of errors like syntax error e.g.

<?php
define("variable" , 10);
variable++;
echo variable;
?>

This code has an error and browser should display it . But browser window is empty

Display error is off as I see in the information given by the phpinfo() in column php core.

I want it to be turned on.

If you want to enable it for all your php projects:

edit the /etc/php5/apache2/php.ini by opening a terminal and typing the following:

gksudo gedit /etc/php5/apache2/php.ini

search for the line.

display_errors = Off

and change Off to On

If you want to enable it for a single website, in your website's .htaccess file add the following line:

php_flag display_errors on

If you edited your php.ini file, a restart for apache is required for the settings to take effect, restart it with following line in a terminal.

sudo apache2ctl restart
