PHP Error Log Ignores log_errors_max_len Setting

Question

When I tail my /var/log/apache2/error_log file, it is truncating some data I am trying to display.

Example:

error_log(serialize($data));

As I understand it, the PHP INI Setting "log_errors_max_len" determines how long this is. And by default is is 1024. Mine is truncating at 8109 characters.

I have changed the value by using:

• ini_set('log_errors_max_len', 0);
• /etc/php5/apache2/php.ini (log_errors_max_len = 0)
• /etc/php5/cli/php.ini (log_errors_max_len = 0)

Note: I am restarting Apache after each change to the php.ini file.

Unfortunately, none of these setting changes seem to change the amount of data that is displayed before truncating.

Anyone have a suggestion?

Thanks!
