How to use strnatcmp function

PHP strnatcmp function: Compare strings using natural sorting algorithm.

php strnatcmp() function syntax

Function: compare strings in natural order

Syntax:

strnatcmp(string1,string2)

Parameters:

string1 Required, specifies the first string to be compared.

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.

php strnatcmp() function usage example:

<?php
//使用自然算法来比较两个字符串
echo strnatcmp("2hello world!","01hello world!");
echo "<br>";
echo strnatcmp("01hello world!","2hello world!");
?>

Output:

1
-1
