The error severity is set to E_ALL On the page, and the error is displayed, but the fatal error is not reported. why error_reporting (E_ALL); ini_set (display_errors, & nbsp; On ); var_dump ($ a) notice errors can be prompted. but the fatal error is not reported. why? (Display_errors & nbsp; & set the error level to E_ALL on the php. ini page. the error is also displayed, but the fatal error is not reported. why?
Error_reporting (E_ALL );
Ini_set ('display _ errors ', 'on ');
Var_dump ($)
A notice error is prompted.
But the fatal error is not reported. why? (Display_errors = Off in php. ini)
Because my page has an error, this page cannot be executed directly, so
Error_reporting (E_ALL );
Ini_set ('display _ errors ', 'on ');
Cannot be executed? But isn't the code executed from top to bottom? I don't understand.

Yes!
Although php is interpreted and executed
However, he still has a pre-compilation process that compiles php scripts into p processor commands. This can speed up code execution.
In fact, all explain execution languages have this process, but the degree of pre-compilation is different.
