Definition and Usage
Definition and usage
The strnatcmp () function compares the strings using a "natural" algorithm.
The strnatcmp () function works by comparing strings (case sensitive) with natural algorithms.

In a natural algorithm, the number 2 was less than the number 10. In computer sorting, than 2, because the first number in "Ten" is less than 2.
In the "Natural algorithms", 2:10 is small. In the computer sequence, 10:2 is small, because the first number in "10" is "1", which is less than 2.
