PHP, namespace and file directory correspondence
There is no direct association, of course, the recommendation of association, or management will be very confusing, but you can actually implement a autoload to manage the "chaos" of the namespace, just do not recommend it
Please refer to:http://php.net/manual/zh/function.spl-autoload-register.php

-intro.md's introduction.Auto LoadIn order to implement the PHP class with fetch and use, the namespace definition of the class recommends following certain rules. This rule can be specified by a project group. However, to make the class library uniform, the Php-fig project specifies a PHP namespace specification PSR-0, which is used by some popular PHP projects. Composer supports this specification of the Class Library auto Loader, just add the AutoL
'. This also explains why there is a result of the above output.
If we want to output ' a ' to ' Z ', the following implementations are a good idea:
for ($i = Ord (' a '); $i
Or it's OK:
$letters = Range (' A ', ' Z ');
for ($i = 0; $i
Error 9: Ignoring the encoding standard

frequently overlooked problem is that any noise, transients, or drift of the power supply voltage vs will be directly added to the output by a reference input that is attenuated by the divider ratio.
