UPDATE 2:
I have now removed the following from the .php file:
<?php error_reporting( E_ALL ); ?>
I have set display_erros in php.ini as follows:
display_errors = On
Error reporting is set to the following in php.ini:
error_reporting = E_ALL | E_STRICT
After restarting Apache, I still get no errors/warnings.
UPDATE 1:
I have changed error_reporting in php.ini from:
error_reporting = E_ALL &
~E_DEPRECATED
to
error_reporting = E_ALL | E_STRICT
After which I restarted Apache, e.g.
/etc/init.d/apache2 restart
But the page will still not display errors/warnings of any kind.
ORIGINAL QUESTION:
The following script is generating a warning because the $err being inside the if statement. Why is this warning not being displayed on the PHP page in a web browser?
I have to look at the Apache logs to see the warning. Also, if I deliberately change the “insert into” to “delete into”, it does not display an error on the PHP page. Why are the errors not displaying on the actual PHP page?

Display errors could be turned off in the
php.inior your Apache configuration file.You can turn it on in the script:
You should see the same messages in the PHP error log.
