error_logOR use the grep command as follows:grep error_log /etc/php.ini grep ^error_log what is sapi in php /etc/php.iniSample outputs:error_log = /var/log/httpd/php_error_logThe error_log directive defines the name of the file where script errors should be logged. The file should be writable by the web server's user. If the special value syslog is used, the errors are sent to the system logger instead. On Unix, this means syslogd and on Windows NT it php.ini error log means the event log. The system logger is not supported on Windows 95. If this directive is not set, errors are sent to the SAPI error logger. For example, it is an error log in Apache (/var/log/httpd/error_log file) or stderr in command line (CLI).This line define exact location for each php instance. If error_log set to syslog, open /var/log/messages file to view log. For example if error_log is set to /var/log/apache/php.errors, type the following to display error log: $ tail -f /var/log/apache/php.errors$ grep something /var/log/apache/php.errors

When I add a file via the WordPress uploader I see it is not uploaded because of a permission issue “cannot-open-file.png” has failed to upload due to an error Unable to create directory wp-content/uploads/2014/05.

When running as a server module, PHP writes all logs to the SAPI logger. For Apache HTTP Server it is the error log file defined in the server configuration file. In PHP, we can change and enhance error reporting to suit our needs. We can customize to what level and kind of error feedback is given, ranging from simple notices to customized functions returned during errors. We can modify the error logging behavior in PHP including the method by which error log is saved or handled. We can selectively log and monitor the important parts of our applications and websites. http://php.net/manual/en/book.errorfunc.php For the convenience, we will break up error reporting in PHP into following three sections. 1) Predefined Constants 2) Bitwise Operators 3) Configuration Options 1) Predefined Constants Predefined Constants inform PHP of which errors, warnings and notices we would like it to take action for. These constants are set as values for configuration options directives in php.ini or other PHP configuration files. We may use these constant names in PHP configuration file(example: php.ini) but not outside of PHP(example: httpd.conf), where we should use bitmask values instead. http://php.net/manual/en/errorfunc.constants.php E_ERROR BITMASK VALUE: 1 Fatal run-time errors. These indicate errors that can not be recovered from, such as a memory allocation problem. Execution of the script is halted. E_WARNING BITMASK VALUE: 2 Run-time warnings (non-fatal errors). Execution of the script is not halted. E_PARSE BITMASK VALUE: 4 Compile-time parse errors. Parse errors should only be generated by the parser. E_NOTICE BITMASK VALUE: 8 Run-time notices. Indicate that the script encountered something that could indicate an error, but could also happen in the normal course of running a script. E_CORE_ERROR BITMASK VALUE: 16 Fatal errors that occu
