PHP error handling with .htaccess & writing into p

Question

For PHP error handling with the aim of "only admin sees the warnings, errors etc.";

I applied the steps below:

1. I deleted error_reporting(-1); command from my index.php
2. I added rows below into my .htaccess which is just under public_html folder
3. I created error_modes folder in my public_html folder
4. I created .htaccess file in error_modes folder
5. I set the permissions of the error_modes folder as 777, writable.
6. intentionally, I wrote <?php 'should see this error in log file' ?> in my footer.inc.php page. Please note that I didn't wrote ; character at the end.

Despite the intentional php syntax error in my footer.inc.php page, no php_error.log file is created!

and I saw that should see this error in log file string is printed in my footer.inc.php page. So php worked despite a syntax error !?

I also added my whole .htaccess code below. (this is the one that is just under public_html)

fyi: I don't have access to php.ini and I don't have any pre-set .log file. PHP version is 5.4.

Can you please correct me? Thanks. Best Regards.

Answer 1

Please try to do the following:

In .htaccess

    # supress php errors
    php_flag display_startup_errors off
    php_flag display_errors off
    php_value docref_root 0
    php_value docref_ext 0


    # enable PHP error logging
    php_flag  log_errors on
    php_value error_log  /correct_path_to_your_website/error_modes/PHP_errors.log


    # general directive for setting php error level
    php_value error_reporting -1

In php file

Instead of intentional mistake in you wrote in your php file you can try doing something like:

    <?

    echo $_SERVER['DOCUMENT_ROOT']; // this will enable you to see 
                                    // the correct path to your website dir 
                                    // which should be written in .htaccess 
                                    // instead of correct_path_to_your_website
                                    // (check it just in case)

    $foo = $bar['nope'];// this should generate notice 

    call_undefined(); // this should generate fatal error


    ?>

Worked good with me)

Hope it'll help.
