PHP error handling

way to email myself all errors in my PHP script?

[meingalls]

I am about to turn my PHP code over to production. I don't want errors displaying on the screen for all site visitors to see (and be confused by!), but at the same time, I still need to know about them and fix them.

To turn off the errors on the screen, I have included at the beginning of each PHP page the following:

error_reporting(0);

As I read the documentation (http://us3.php.net/manual/en/ref.errorfunc.php), it appears that I can have errors emailed to me using the error_log function, but I am not sure how to detect that an error has occurred during the course of executing a script. Can someone please enlighten me? Perhaps even a sample script?

Thank you!

Here's a bit of script I'm using:

function myErrorHandler($errno, $errstr, $errfile, $errline) { 
 $out = ''; 
 switch ($errno) { 
  case E_PARSE: 
   $out .= sprintf("Parse error. Error nr: %s\nError: %s\nFile: %s\nLine: %s\n\nStopping...", $errno, $errstr, $errfile, $errline); 
   exit(1); 
   break; 
  case E_ERROR: 
   $out .= sprintf("An error occured. Error nr: %s\nError: %s\nFile: %s\nLine: %s\n\nStopping...", $errno, $errstr, $errfile, $errline); 
   exit(1); 
   break; 
  case E_WARNING: 
   $out .= sprintf("Warning. Error nr: %s\nError: %s\nFile: %s\nLine: %s", $errno, $errstr, $errfile, $errline); 
   break; 
  case E_NOTICE: 
   $out .= sprintf("Notice. Error nr: %s\nError: %s\nFile: %s\nLine: %s", $errno, $errstr, $errfile, $errline); 
   break; 
  case E_STRICT: 
   $out .= sprintf("Strict mode problem. Error nr: %s\nError: %s\nFile: %s\nLine: %s", $errno, $errstr, $errfile, $errline); 
   break; 
  default: 
   $out .= sprintf("Some other error. Error nr: %s\nError: %s\nFile: %s\nLine: %s", $errno, $errstr, $errfile, $errline); 
   break; 
 } 
 if (!empty($out)) { 
  if (!doMail($out)) { 
   echo '<p>', nl2br($out), '</p>'; 
  } 
 } 
} 
  
function doMail($text) { 
 $succes = false; 
 // restore to default error handling, in order to prevent recursive calling of myErrorHandler if mail() fails 
 restore_error_handler(); 
 if (@mail ('[e-mail]', 'error on site', $text)) { 
  $succes = true; 
 } 
 set_error_handler('myErrorHandler'); 
 return $succes; 
} 
  
set_error_handler('myErrorHandler'); 

IIRC I basically copied it from [php.net...] and added the mailing feature. The script will mail an error report. If mail() fails, the report will be output to stdout, i.e. to screen.

Sorry for the long lines. I used a combination of

pre

and

small

, which worked fine in preview mode...

Thank you, RonPK. This is great!

RonPK,

I find that I am getting emails for every variable reference that addresses an undefined variable. For example, if I have a statement that says:

if (@$foo) $bar = 1;

and $foo is not defined, I get an email error message. Given that I have prefaced the reference to $foo with the "@", so that it does not generate an error, I would not consider this an error.

Is there a way to modify the code you listed so that it will still generate an error if I didn't have the "@" but not if I do?

Thanks!

take a look at the link RonPK poster for set_error_handler, most of the information you need should be there

Got it! Thank you!
