The "Notice" level error reporting mechanisim has two bugs. These problems arise when error_reporting() is set to 8 or 15. 1) Not all programming errors are reported. For example: <?php error_reporting(15); # In PHP 3.0.11, that's reported as "Bad escape sequence." # In PHP 4.0.2, no error is reported. $X = "c:\dirname"; # This causes a parse error in both versions. $Y = "sala"mala"; ?> 2) System crashes when a "Notice" level error is encountered. Below are some code samples. The first two samples run fine, as they should. The third sample crashes, which it should not. <?php # Okee dokee. error_reporting(15); $Blah = "whoopee"; echo "<br />Blah: $Blah"; ?> <?php # No sweat. error_reporting(0); echo "<br />Rah: $Rah"; ?> <?php # Crashes on PHP 4.0.2, Windows NT 4.0, Apache 1.3.6. error_reporting(15); echo "<br />Rah: $Rah"; /* NOTE: No problems when: error_reporting(1); error_reporting(2); error_reporting(4); */ ?> Here's Dr. Watson Report.......
