PHP中的致命错误是什么意思？

Question

I'm getting the following error:

Fatal error: Uncaught Error: Call to undefined function var_dumb()

What does this mean?

Answer 1

You have a typo in your code. var_dumb should be var_dump. Because PHP doesn't know a function by the name of var_dumb, it doesn't know what to do. A fatal exception is thrown, and execution of the script halts.
