Hello Dear,

Please Tell Me How many error levels are available in PHP?

[Servers Base]

1. E_ERROR-A fatal run-time error, that can't be recovered from. The execution of the script is stopped immediately.
2. E_WARNING-A run-time warning. It is non-fatal and most errors tend to fall into this category. The execution of the script is not stopped.
3. E_PARSE-The compile-time parse error. Parse errors should only be generated by the parser.
4. E_NOTICE- A run-time notice indicating that the script encountered something that could possibly an error, although the situation could also occur when running a script normally.
5. E_CORE_ERROR- A fatal error that occur during the PHP's engine initial startup. This is like an E_ERROR, except it is generated by the core of PHP.
