This will display all the errors including syntax or parse errors that cannot be displayed by just calling the ini_set function in the PHP code. The display_errors directive must be set to “on” in the PHP ini file. If adding some of the PHP code errors doesn’t show in the browser during testing, then the PHP ini configuration has some additional directives to handle this. In this case, the PHP ini configuration must be modified. Unfortunately, these two directives won’t be able to display parse errors such as missing semicolons or missing curly braces. The list of directives that can be overridden by the ini_set function is found in the official documentation. The display_startup_errors, however, is a separate directive because the display_errors don’t handle the errors that will be encountered during PHP’s startup sequence. Usually, the dispay_errors directive should be turned off after development. The display_errors directive will determine if the errors will be displayed or hidden from the user. The display_errors and display_startup_errors are just two of the directives that are available. The ini_set function will try to override the configuration found in your PHP ini file. The quickest way to display all php errors and warnings is to add these lines to your PHP code file: ini_set('display_errors', 1) We will also discuss how to write the errors to a log file and even collect them via the Retrace’s error tracking feature. In this tutorial, we will explain all the different ways to enable PHP errors and warnings. If you are having problems with your PHP web application and need to display all the errors and warnings, you are in the right place. It could be sent to the server’s error log, a TCP port, or a separate file specified in the directive. error_log string: This directive determines where the error message should be sent.If set to “On”, it will log errors according to what is set in the error_log directive. log_errors: This directive tells PHP whether it should log errors.display_errors: This is a directive in the php.ini file that determines whether errors should be printed to the screen as part of the output or if they should be hidden.It can be set to display all errors, warnings, and notices except for some exceptions like E_NOTICE and E_STRICT. error_reporting: This function allows developers to determine which errors PHP will suggest.Four different ways to display errors in PHPīefore diving into the details of managing and logging errors in PHP, let’s outline the four main ways to display errors in PHP: ![]() With the complexity of PHP web applications, there are multiple methods to display errors, each with advantages depending on your specific use case. Identifying and fixing these problems becomes a complicated guessing game without visible errors. Furthermore, they bring attention to more complex issues that need to be debugged. They also notify developers about missing semicolons, which are important punctuation marks in certain programming languages. They inform developers about syntax errors, which are mistakes made while writing code. Error messages provide vital information about issues that occur while running a PHP script. Understanding the importance of displaying errors in PHP can’t be overstated. However, many developers often encounter difficulties displaying errors in their PHP applications, leading to silent app failures. Seeing these errors is crucial for developers when troubleshooting a misbehaving application. A PHP application might produce many different levels of warnings and errors during its execution.
