How To Make Error Log File In Php
vote 116 down vote favorite 33 How to turn on all error and warnings and log them to a file but to set up all of that within the script (not changing anything in php.ini).

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.

Normally the error_log() function just works and you have not said what exactly did not work for you so your question is not clear. –hakre Mar 20 '13 at 17:06 Tutorial on this: code2real.blogspot.in/2015/06/… –Pupil Jul 16 '15 at 4:00 add a comment| 5 Answers 5 active oldest votes up vote 68 down vote If you don't want to change anything in your php.ini file, according to PHP documentation, you can do this. error_log("Error message\n", 3, "/mypath/php.log"); The first parameter is the string to be sent to the log. The second parameter 3 means expect a file destination.

Basics Configuration Settings Built-In Logging Functions Logging Levels Application Error Logging Custom Logging with JSON Exceptions ↑ 0 PHP Logging Basics This guide explores the basics of logging https://www.loggly.com/ultimate-guide/php-logging-basics/ in PHP, where to find PHP logs, and how these logs help you more effectively troubleshoot problems and monitor your PHP application. There are a couple of different elements https://devcenter.heroku.com/articles/php-logging you’ll want to consider logging: Errors emitted by the PHP engine itself when a core function fails or if code can’t be parsed Custom errors that your application triggers, usually log file caused by missing or incorrect user input Activities in your application that you may want to analyze at a later time, such as recording when a user account is updated or content in a CMS is updated Configuration Settings Let’s start by surveying how the PHP engine can be configured to display and log error output. These settings are error log file useful to review if you’re setting up a new server or trying to figure out where errors are being logged on a server that someone else has configured. Default Configuration By default, PHP configuration pertaining to errors is found in the following directives within the configuration file php.ini. Here is where you can find your php.ini file in common distributions of Linux: Table of Default Configuration Paths OS Path Type Debian-Based (Debian, Ubuntu, Linux Mint, etc.) /etc/php5/apache2/php.ini Apache module Redhat/Fedora/CentOS /etc/php.ini All PHP versions OpenSUSE /etc/php5/apache2/php.ini Apache module Here are common directives you can configure in this file relevant to logging: Table of Logging Directives Directive Default Setting Recommend Production Server Setting Description *docref_root 1 0 An error format containing a documentation page reference **display_errors 1 0 Defines whether error output is sent along with regular output display_startup_errors 0 0 Whether to display PHP startup sequence errors error_append_string null null String to output after an error message ***error_log null “/path/to/log/file” File path to a writable (by web server user) error log file.

Most PHP frameworks can be configured to write appropriate log output, and this article provides examples for some common libraries and frameworks. Logging using PHP or libraries Logging from plain PHP The normal PHP error log is automatically sent to stderr, and any message logged using the error_log function will thus be available in heroku logs: error_log("hello, this is a test!"); The alternative approach, is writing to the php://stderr stream directly: file_put_contents("php://stderr", "hello, this is a test!\n"); Make sure you always terminate a message with a trailing newline character like in the example above when manually writing to stderr! Logging using Monolog If you’re using the excellent Monolog library for PHP (and you should!), you can simply use a StreamHandler to write to php://stderr: use Monolog\Logger; use Monolog\Handler\StreamHandler; $log = new Logger('name'); $log->pushHandler(new StreamHandler('php://stderr', Logger::WARNING)); $log->addWarning('Foo'); In this example, the logger will only log messages with level “warning” and higher. Refer to the Monolog documentation for all usage instructions. Logging when using web frameworks CodeIgniter Unfortunately, CodeIgniter doe
