Function:Natural order method to compare strings
Syntax: strnatcmp(string1,string2)
Parameters ：
| Parameter | Description |
| string1 | Required, specified The first string to compare. |
| string2 | Must specify the second string to be compared. |
Description: The strnatcmp() function uses a "natural" algorithm to compare two strings. In natural arithmetic, the number 2 is less than the number 10. In computer sorting, 10 is less than 2 because the first number in 10 is less than 2. Note that this function is case-sensitive. If the two strings are equal, 0 is returned. If string1 is greater than string2, the returned value is greater than 0. If string1 is less than string2, the returned value is less than 0.
