Show Php Error
Errors to display? up vote 664 down vote favorite 197 I have checked my PHP ini file and display errors is set and also error reporting is E_ALL. I have restarted my apache web server. I have even put these lines at the top of my script and it doesn't even catch simple parse errors. For example, I declare variables with a "$" and I don't php display error close statements";". But all my scripts show a blank page on these errors, but i want to actually see the errors in my browser output. error_reporting(E_ALL); ini_set('display_errors', 1); What is left to do? php error-reporting share|improve this question edited Mar 9 at 7:16 Maninderpreet Singh 1,7111524 asked Jun 27 '09 at 19:09 Abs 13.2k68208356 3 I've yet to nail down exactly why this works sometimes and not others, but for anyone wanting to quickly toggle errors in a php script (or enable them via a $_REQUEST parameter) these two lines will work most of the time. –brandonscript Oct 28 '13 at 20:15 well you can see details of the error by enabling xdebug from php ini file. –jewelhuq Jan 13 at 10:14 add a comment| 13 Answers 13 active oldest votes up vote 1335 down vote accepted This always works for me: ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL); However, this doesn't make PHP to show parse errors - the only way to show those errors is to modify your php.ini with this line: display_errors = on share|improve this answer edited Oct 23 '15 at 12:24 tleb 1,164721 answered Jan 29 '14 at

and found it very interesting, thought it might be something for you. The article is called How to Debug in PHP and is located at http://blog.teamtreehouse.com/how-to-debug-in-php.CaptchaSubmitNobody enjoys the process of debugging their code. If you want to build killer web apps though, it's vital that you understand the process thoroughly. This article breaks down the fundamentals of debugging in PHP, helps you understand PHP's error messages and introduces you to some useful tools to help make the process a little less painful. Doing your Ground Work It is important that you configure PHP correctly and write your code in such a way that it produces meaningful errors at the right time. For example, it is generally good practice to turn on a verbose level of error reporting on your development platform. This probably isn't such a great idea, however, on your production server(s). In a live environment you neither want to confuse a genuine user or give malicious users too much information about the inner-workings of your site. So, with that in mind lets talk about the all too common "I'm getting no error message" issue. This is normally caused by a syntax error on a platform where the developer has not done their ground work properly. First, you should turn display_errors on. This can be done either in your php.ini file or at the head of your code like this: ini_set('display_errors', 'On'); Tip: In these code examples I omit the closing (?>) PHP tag. It is generally considered good practice to do so in files which contain only PHP code in order to avoid accidental injection of white space and the all too common "headers already sent" error. Next, you will need to set an error reporting level. As default PHP 4 and 5 do not show PHP notices which can be important in debugging your code (more on that shortly). Notices are generated by PHP whether they are displayed or not, so deploying code with twenty notices being generated has an impact upon the overhead of your site. So, to ensure notices are displayed, set your error reporting level either in your php.ini or amend your runtime code to look like this: ini_set('display_errors', 'On');
error_reporting(E_ALL); Tip: E_ALL is a constant so don't make the mistake of enclosing it in quotation marks. With PHP 5 it's also a good idea to turn on the E_STRICT level of error reporting. E_STRICT is useful for ensuring you're coding using the best possible standards. For example E_STRICT helps by warning you that you're using a deprecated function. Here's how to enable it at runtime: ini_set('display_error
