Syntax
error_reporting(report_level)

| 1 | E_ERROR | Fatal run-time errors. Errors that can not be recovered from. Execution of the script is halted |
| 2 | E_WARNING | Non-fatal run-time errors. Execution of the script is not halted |
| 4 | E_PARSE | Compile-time parse errors. Parse errors should only be generated by the parser |
| 8 | E_NOTICE | Run-time notices. The script found something that might be an error, but could also happen when running a script normally |
| 16 | E_CORE_ERROR | Fatal errors at PHP startup. This is like an E_ERROR in the PHP core |
