Reporting Errors
Reporting Errors
To report errors from an internal function, you should call the php3_error() function. This takes at least two parameters -- the first is the level of the error, the second is the format string for the error message (as in a standard printf() call), and any following arguments are the parameters for the format string. The error levels are:
E_NOTICE
Notices are not printed by default, and indicate that the script encountered something that could indicate an error, but could also happen in the normal course of running a script. For example, trying to access the value of a variable which has not been set, or calling stat() on a file that doesn't exist.
E_WARNING
Warnings are printed by default, but do not interrupt script execution. These indicate a problem that should have been trapped by the script before the call was made. For example, calling ereg() with an invalid regular expression.
E_ERROR
Errors are also printed by default, and execution of the script is halted after the function returns. These indicate errors that can not be recovered from, such as a memory allocation problem.
E_PARSE
Parse errors should only be generated by the parser. The code is listed here only for the sake of completeness.
E_CORE_ERROR
This is like an E_ERROR, except it is generated by the core of PHP. Functions should not generate this type of error.
E_CORE_WARNING
This is like an E_WARNING, except it is generated by the core of PHP. Functions should not generate this type of error.
E_COMPILE_ERROR
This is like an E_ERROR, except it is generated by the Zend Scripting Engine. Functions should not generate this type of error.
E_COMPILE_WARNING
This is like an E_WARNING, except it is generated by the Zend Scripting Engine. Functions should not generate this type of error.
E_USER_ERROR
This is like an E_ERROR, except it is generated in PHP code by using the PHP function trigger_error(). Functions should not generate this type of error.
E_USER_WARNING
This is like an E_WARNING, except it is generated by using the PHP function trigger_error(). Functions should not generate this type of error.
E_USER_NOTICE
This is like an E_NOTICE, except it is generated by using the PHP function trigger_error(). Functions should not generate this type of error.
E_ALL
All of the above. Using this error_reporting level will show all error types.
