It's a little work, but it goes along way –Daryl Gill Dec 21 '12 at 2:53 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote accepted Consider set_error_handler: http://php.net/manual/en/function.set-error-handler.php Example: set_error_handler("someFunction"); function someFunction($errno, $errstr) { output details and information } share|improve this answer answered Dec 21 '12 at 3:00 djdy 4,51022455 add a comment| up vote 0 down vote You should have thrown an Exception with custom message you wished to display. You can either suppress the default PHP error message for individual statements by preceding them with an '@' symbol. Or you might change error_reporting level per page( check this link for more details:http://php.net/manual/en/function.error-reporting.php Also check the folowing code snippet $file='example.txt'; //replace the file name with your URL $newfile = 'example.txt.bak'; try{ $ret=@copy($file, $newfile); if (!$ret){ throw new Exception("File path doesn't exist.."); } } catch(Exception $e){ echo $e->getMessage(); } share|improve this answer answered Dec 21

Errors can be categorized as syntactical, run-time, or logical: missing the semicolon at the end of a statement is an example of a syntax error; trying to connect to a database when the server error message is down is an example of a run-time error; providing incorrect data to a variable is an example of a logic error. To help reduce the number of errors in your code, and to mitigate their effects, proper error handling is essential in your web application. This article is a crash course in PHP error handling. You'll learn about PHP's built-in error creating error messages reporting levels, and how to handle errors with custom error handlers and exception handling. PHP Error Reporting Levels All errors and warnings should be logged. Based on the severity of an error, notifications should be sent out to other systems/teams. So that you can better gauge its severity, PHP provides several built-in error levels to describe the nature of an error. Each level is represented by an integer value and named constant which can be used by the programmer. The table below is taken from the official PHP documentation and shows some of the different levels. The levels can be masked together with bit-operators to include or subtract them from PHP's configuration. For example, E_ALL|E_STRICT enables all errors and warnings with the addition of E_STRICT (necessary in versions of PHP prior to 5.4). PHP provides a few configuration directives related to logging and displaying errors. Their values are generally different depending on whether the system is in a development or a production environment. This table shows some of the error-related directives. The configuration directives can be set either in php.ini, in a web s

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.
