| E_WARNING | 2 | Run-time warnings (non-fatal errors). Execution of the script is not halted. | |
| E_PARSE | 4 | Compile-time parse errors. Parse errors should only be generated by the parser. | |
| E_NOTICE | 8 | Run-time notices. Indicate that the script encountered something that could indicate an error, but could also happen in the normal course of running a script. | |
| E_CORE_ERROR | 16 | Fatal errors that occur during PHP's initial startup. This is like an E_ERROR, except it is generated by the core of PHP. | |
