 E_NOTICEValue 8. Not exactly an error, but a hint that you may be doing something you don't want to.
 E_CORE_ERRORValue 16. Fatal error that occurs when the PHP engine starts. You cannot run any PHP scripts if this error occurs.
 E_CORE_WARNINGValue 32. Nonfatal error that occurs when the PHP engine starts. You can still run PHP scripts, but you may have one or more problems depending on the error.
 E_COMPILE_ERRORValue 64. Occurs when the script is compiled. A kind of fatal error.
 E_COMPILE_WARNINGValue 128. occurs when the script is compiled. A kind of Nonfatal error.
