Description of Case sensitivity in php.

For beginners of php, we should first understand the case sensitivity of php and start to develop a good coding habit, which is good for further learning.

PHP syntax is somewhat special, one of which is Case sensitivity.

In PHP, variable names are case-sensitive, while function and class names are case-insensitive.

This is a significant difference between him and other programming languages. These 1.1 must be noted to avoid unnecessary errors.

However, we recommend that you do not use variable names with the same name and case to avoid confusion.
