PHP's error levels

Question

The only error level in PHP that will halt the script but can be caught and dealt with have to be triggered with the trigger_error() function correct? I'm referring to the "E_USER_ERROR" error level. The "E_ERROR" error will simply halt the script and I can't do anything about it as the developer.

Answer 1

E_ERROR will simply stop the script. It's meant to be used for:

Fatal run-time errors. These indicate errors that can not be recovered from, such as a memory allocation problem. Execution of the script is halted.

You cannot handle the following other error types for similar reasons:

• E_PARSE
• E_CORE_ERROR
• E_CORE_WARNING
• E_COMPILE_ERROR
• E_COMPILE_WARNING

set_error_handler() however can handle the follow errors:

• E_WARNING
• E_NOTICE
• E_USER_ERROR (using trigger_error)
• E_USER_WARNING (using trigger_error)
• E_USER_NOTICE (using trigger_error)
• E_STRICT
• E_RECOVERABLE_ERROR
