A Guide To PHP Error Messages For Designers By Rachel Andrew November 30th, 2011 PHP 15 Comments PHP is widely available with inexpensive hosting plans, which makes it a popular choice for developers who write software for the Web. From big platforms, such as WordPress, down to small scripts, such as ones to display image galleries or to send forms to email, thousands of script and products are out there written in PHP that can be installed and used even if you don’t know much about PHP yourself. I have been a PHP developer for 10 years, and my company has developed a content management system, written in PHP, that is intended to be very simple to install and get started with. So, I spend a lot of time working with designers who are installing a PHP script for the first time. If you are installing a script and something goes wrong, PHP can be incredibly infuriating. Until you know what they mean, PHP errors can be baffling. My favorite message is: Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM Paamayim Nekudotayim means “double colon” in Hebrew! But double colon is a lot easier to debug than T_PAAMAYIM_NEKUDOTAYIM. This article is aimed at designers who are not PHP developers but need to install PHP scripts from time to time. Thus, the problems and error messages we will look at here are those you are most likely to encounter when installing scripts, rather than when writing PHP. The tips should help you work through other error messages and should at least help you give clear information to the script’s developer if you need to ask them for assistance. “All I Get Is A Blank Page!” Link Before we can diagnose PHP errors, we need to see some PHP errors. Ideally, you would first be installing the script locally, perhaps using MAMP on a Mac or XAMPP, both of which allow you to turn on error messages easily. You can get PHP to just spit the errors out directly on the screen or log them to a file for view

I have restarted php error 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 close statements";".

The Zend parser (the one used by php) is executed before the script is executed. So, if the script has syntactic errors, these ini_set directives are never executed and every existing syntactic error is never displayed; only logged. If you want to show syntactic errors, you have to set display_errors and error_reporting directives in the ph

Quite often I will try and run the script and just get a blank screen back. No error message, just empty screen. The cause might have been a simple syntax error (wrong bracket, missing semicolon), or a failed function call, or something else entirely. It is very difficult to figure out what went wrong. I end up commenting out code, entering "echo" statements everywhere, etc. trying to narrow down the problem. But there surely must be a better way, right?. So, is there a way to get PHP to produce useful error message like Java does? Can anyone recommend good PHP debugging tips, tools and techniques? php debugging error-handling share|improve this question edited May 11 '13 at 23:52 hkBattousai 3,67183982 asked May 10 '09 at 9:48 Candidasa 2,95982330 coding.smashingmagazine.com/2011/11/30/… –Alex Jul 15 '12 at 14:54 1 Also see stackoverflow.com/q/1475297/632951 –Pacerier Oct 14 '14 at 9:37 @JuannStrauss, That's understating it. And when you finally see the errors, it says T_PAAMAYIM_NEKUDOTAYIM. Or maybe "must be an instance of integer, integer given". –Pacerier Apr 3 '15 at 20:02 Tutorial on this: code2real.blogspot.com/2015/06/… –Pupil Sep 9 '15 at 7:21 add a comment| 27 Answers 27 active oldest votes up vote 355 down vote accepted For syntax errors, you need to enable error display in the php.ini. By default these are turned off because you don't want a "customer" seeing the error messages. Check this page in the PHP documentation for information on the 2 directives: error_reporting and display_errors. display_errors is probably the one you want to change. If you can't modify the php.ini, you can al
