PHP function strnatcmp
This function uses a 'natural order' algorithm for string comparision. This comparision is case-sensitive.
Syntax strnatcmp
- string1: string input.
- string2: string input.
strnatcmp(string1,string2)
Return
- 0: when two string equal.
- >0: string1 is greater than string2.
- <0: string2 is greater than string1.
Example 1
<?php
echo strnatcmp ("apple" , "Apple");
?>
Output
1
Example 2
<?php
echo strnatcmp ("apple" , "apple1");
?>
Output
-1
Example 3
<?php
$aa1 = $aa2 = array('app1',
'app0',
'App0',
'app3',
'app12',
'app02',
'app122',
'app2');
echo 'Standard Shorting Order<br/>';
usort($aa1, "strcmp");
print_r($aa1);
echo 'Natural Algorithm Order<br/>';
usort($aa2, "strnatcmp");
print_r($aa2);
?>
Output

)
