Summary

0000672: trigger_error or set_error_handler not working

Description

I haven't debugged this yet...

The following script is from http://us3.php.net/set_error_handler [^]

<?php
// set the error reporting level for this script
error_reporting(E_USER_ERROR | E_USER_WARNING | E_USER_NOTICE);

// error handler function
function myErrorHandler($errno, $errstr, $errfile, $errline)
{
  switch ($errno) {
  case E_USER_ERROR:
   echo "My ERROR [$errno] $errstr
\n";
   echo " Fatal error in line $errline of file $errfile";
   echo ", PHP " . PHP_VERSION . " (" . PHP_OS . ")
\n";
   echo "Aborting...
\n";
   exit(1);
   break;
  case E_USER_WARNING:
   echo "My WARNING [$errno] $errstr
\n";
   break;
  case E_USER_NOTICE:
   echo "My NOTICE [$errno] $errstr
\n";
   break;
  default:
   echo "Unkown error type: [$errno] $errstr
\n";
   break;
  }
}

// function to test the error handling
function scale_by_log($vect, $scale)
{
  if (!is_numeric($scale) || $scale <= 0) {
   trigger_error("log(x) for x <= 0 is undefined, you used: scale = $scale", E_USER_ERROR);
  }

  if (!is_array($vect)) {
   trigger_error("Incorrect input vector, array of values expected", E_USER_WARNING);
   return null;
  }

  for ($i=0; $i<count($vect); $i++) {
   if (!is_numeric($vect[$i]))
     trigger_error("Value at position $i is not a number, using 0 (zero)", E_USER_NOTICE);
     $temp[$i] = log($scale) * $vect[$i];
   }
   return $temp;
  }

// set to the user defined error handler
$old_error_handler = set_error_handler("myErrorHandler");

// trigger some errors, first define a mixed array with a non-numeric item
echo "vector a\n";
$a = array(2,3, "foo", 5.5, 43.3, 21.11);
print_r($a);

// now generate second array, generating a warning
echo "----\nvector b - a warning (b = log(PI) * a)\n";
$b = scale_by_log($a, M_PI);
print_r($b);

// this is trouble, we pass a string instead of an array
echo "----\nvector c - an error\n";
$c = scale_by_log("not array", 2.3);
var_dump($c);

// this is a critical error, log of zero or negative number is undefined
echo "----\nvector d - fatal error\n";
$d = scale_by_log($a, -2.5);

?>

It is supposed to output something like:

vector a
Array
(
    [0] => 2
    [1] => 3
    [2] => foo
    [3] => 5.5
    [4] => 43.3
    [5] => 21.11
)
----
vector b - a warning (b = log(PI) * a)
WARNING [1024] Value at position 2 is not a number, using 0 (zero)

Array
(
    [0] => 2.2894597716988
    [1] => 3.4341896575482
    [2] => 0
    [3] => 6.2960143721717
    [4] => 49.566804057279
    [5] => 24.165247890281
)
----
vector c - an error
ERROR [512] Incorrect input vector, array of values expected

NULL
----
vector d - fatal error
FATAL [256] log(x) for x <= 0 is undefined, you used: scale = -2.5

Fatal error in line 36 of file trigger_error.php, PHP 4.0.2 (Linux)

Aborting...

INSTEAD IT outputs only:

vector a
Array
(
    [0] => 2
    [1] => 3
    [2] => foo
    [3] => 5.5
    [4] => 43.3
    [5] => 21.11
)
----
vector b - a warning (b = log(PI) * a)
/C:/Resin/resin/webapps/ROOT/triggererror.php:38: Fatal Error: log(x) for x <= 0 is undefined, you used: scale = M_PI

In other words... vector b was only supposed to issue a warning.
