But apache + php does not log errors.

necessary to get feedback about the activity and performance of the server as well as any problems that may be occurring. The Apache HTTP https://httpd.apache.org/docs/2.4/logs.html Server provides very comprehensive and flexible logging capabilities. This document describes how to configure its logging capabilities, and how to understand what the logs contain.

In addition to this, third-party modules may provide logging capabilities, or inject entries into the existing log files, and applications such as CGI programs, or PHP scripts, or other handlers, may send messages to the server error log. In this php error log document we discuss the logging modules that are a standard part of the http server. Security Warning Anyone who can write to the directory where Apache httpd is writing a log file can almost certainly gain access to the uid that the server is started as, which is normally root. Do NOT give people write access to the directory the logs are stored in without being aware of the consequences; see the security tips document for details. In addition, log files may contain information supplied directly by the client, without escaping. Therefore, it is possible for malicious clients to insert control-characters in the log files, so care must be taken in dealing with raw logs. Error Log Related ModulesRelated DirectivescoreErrorLogErrorLogFormatLogLevel The server error log, whose name and location is set by the ErrorLog directive, is the most important log file. This is the place where Apache httpd will send diagnostic information and record any errors that it encounters in processing requests. It is the first place to look when a problem occurs with starting the server or with the operation of the server, since it will often contain details of what went wrong and how to fix it. The

Tracking your site’s PHP errors is an excellent way to manage and troubleshoot unexpected issues related to plugins and themes. Even better, monitoring PHP errors behind the scenes via private log is far better than trying to catch them as they appear at random visits. Thanks to the magical powers of htaccess, there is an easy way to implement this effective strategy. Hide PHP errors from visitors In our article, , we discuss a technique whereby PHP errors are suppressed via htaccess. This is done by including the following htaccess directives to your domain’s httpd.conf or to your site’s root (or other target directory) htaccess file: # supress php errors php_flag display_startup_errors off php_flag display_errors off php_flag html_errors off With that in place, PHP errors will no longer be displayed publicly on your site. This eliminates a potential security risk, and keeps those ugly, unintelligible PHP errors from breaking your site layout and disorienting your visitors. No editing required for this code. Enable private PHP error logging Now that we have hidden PHP errors from public view, let’s enable the logging of PHP errors so that we can privately keep track of them. This is done by including the following htaccess directives to your domain’s httpd.conf or to your site’s root (or other target directory) htaccess file: # enable PHP error logging php_flag log_errors on php_value error_log /home/path/public_html/domain/PHP_errors.log For this to work, you will need to edit the path in the last line to reflect the actual location of your PHP_errors.log file. Of course, you will need to create this file and subsequently set the file permissions to 755 or, if necessary, 777. Finally, you need to secure the log file itself by adding this final line of code to your htaccess file: # prevent access to PHP error log
