PHP strnatcasecmp function: Use the "natural order" algorithm to compare strings (not case-sensitive)

php strnatcasecmp() function syntax

Function : Use the "natural" algorithm to compare two strings (case-insensitive):

Syntax:

strnatcasecmp(string1,string2)

Parameters:

string1 Required, specifies the number to be compared a string.

string2 Required, specifies the second string to be compared.

Description: The strnatcasecmp() 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. strnatcasecmp() is not 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

<?php
echo strnatcasecmp("2hello world!","01hello world!");
echo "<br>";
echo strnatcasecmp("01hello world!","2hello world!");
