Not useful for code that has parse errors because the error will be before the code is executed. Instead write those changes into the php.ini. –hakre Apr 16 '13 at 23:31 7 If you can't edit php.ini, you should be able to add this in the .htaccess : php_flag log_errors on php_value error_log /home/path/public_html/domain/PHP_errors.log. See perishablepress.com/… –Matthieu Jan 8 '14 at 8:47 I have a question, how to get the error.log file to get created in my htdocs folder instead? –Tommy Mar 5 '14 at 21:51 I guess you just change the folder from tmp/php-error.log to which ever location you desire? –Luke Apr 16 '14 at 12:37 This crashes my PHP in 5.4.0 –Supuhstar May 10 '

it is also possible to instead log PHP errors to a file of your choice. This is useful on production websites so you can periodically check for errors http://www.electrictoolbox.com/log-php-errors-log-errors-error-log/ and fix them in a location other than the default webserver error log file. log_errors The log_errors configuration option is a boolean option. To log to an error log file specified with the error_log configuration option https://github.com/facebook/hhvm/issues/3558 set this to 1. error_log The error_log configuration option is a string and is the filename of where to log errors. It can contain either a relative path or an absolute path as part of php error the filename. If "syslog" is used it is logged to to the system logger (syslog on *nix and the Event Log on Windows). Set error logging with ini_set() Although this is not ideal you can use the ini_set() function to set the above configuration options to log errors. It is not an ideal solution because it will not log any errors if the script has parse errors and cannot be run at php error log all. For example: ini_set("log_errors", 1); ini_set("error_log", "/path/to/php-error.log"); Set error logging in .htaccess and virtualhost directives This is a better option because it will log the errors even if there's a parsing error in your script. php_value log_errors 1 php_value error_log /path/to/php-error.log Example error log data A couple of example lines from an error log are as follows: [13-May-2009 21:54:04] PHP Notice: Undefined variable: x in /common/websites/test/error-log.php on line 6 [13-May-2009 21:54:09] PHP Parse error: syntax error, unexpected '}' in /common/websites/test/error-log.php on line 5 Error log must be writable by the web server The error log will be written to as the user the web server runs as so it must be writeable by that user. In most cases you'll probably need to make it world-writeable to be able to do this. On a *nix server this is 0666 file permissions. Conclusion It's easy to set up a PHP error log using the log_errors and error_log configuration options. This can be set up on a website by website basis and you could potential combine it with a daily process to email errors to the webmaster (if there are any) on a daily basis. I'll cover doing this in a later post. Related posts: Backtracing with PHP Part 1Get and modify the error reporting
