Did you check apache’s error_log for information from PHP? I think the
default setup would be for php’s errors to go there.

What I expected to happen and what appears to be happening can be
observed by by quickly poking around with my PHP’s CLI. I uncommented
the entire “variables_order” paragraph in the “Quick Reference
Section” of my CLI php.ini and got the following:

    ohnobinki at ohnopublishing /tmp/check-0.9.10 $ php -a
    PHP:  syntax error, unexpected '"' in /etc/php/cli-php5.4/php.ini on line 175
    Interactive shell
    
    php > echo ini_get('upload_max_filesize') . PHP_EOL;
    2M
    php > exit
    ohnobinki at ohnopublishing /tmp/check-0.9.10 $ grep -e max_filesize /etc/php/cli-php5.4/php.ini
    upload_max_filesize = 20M
    ohnobinki at ohnopublishing /tmp/check-0.9.10 $ # as root I fixed the directive
    ohnobinki at ohnopublishing /tmp/check-0.9.10 $ php -a
    Interactive shell
    
    php > echo ini_get('upload_max_filesize') . PHP_EOL;
    20M

The original values in your php.ini were the defaults from the PHP
installation. You can see the default for upload_max_filesize at
http://docs.php.net/upload-max-filesize (scroll up to the “File
Uploads” section heading under which this setting is grouped). The
parsing error was so bad that PHP was unwilling to parse the rest of
the php.ini file in question. The error message, which the CLI writes
to stderr, was (likely) written to apache’s error_log—not to the
browser.

I suggest that you experiment a bit more with php.ini. Put the syntax
error back in on purpose, restart apache, and then look in your logs
for the syntax error message. I was able to find “PHP: syntax error,
unexpected '"' in /etc/php/apache2-php5.4/php.ini on line 136” in my
error_log when purposefully creating a syntax error there. This would
have led you straight to the problem line in the .ini and helped you
avoid a lot of trouble ;-). If you cannot find these errors,
double-check the value of your php.ini’s error_log directive and also
that its log_errors directive is “On”.
