Hello all,
I'm having an infuriating issue with number comparison. Basically I've written a script that runs in cygwin that SSH's to 4 servers, figures out a success percentage and if it is less than a certain point, triggers an alarm. I've managed to get it to connect to the servers, figure out... (5 Replies)

strnatcmp
STRNATCMP(3) 1 STRNATCMP(3)strnatcmp - String comparisons using a "natural order" algorithm
SYNOPSIS
int strnatcmp (string $str1, string $str2)
DESCRIPTION
This function implements a comparison algorithm that orders alphanumeric strings in the way a human being would, this is described as a
"natural ordering". Note that this comparison is case sensitive.
PARAMETERS
o $str1
- The first string.
o $str2
- The second string.
RETURN VALUES
Similar to other string comparison functions, this one returns < 0 if $str1 is less than $str2; > 0 if $str1 is greater than $str2, and 0
if they are equal.
EXAMPLES
An example of the difference between this algorithm and the regular computer string sorting algorithms (used in strcmp(3)) can be seen
below:
<?php
$arr1 = $arr2 = array("img12.png", "img10.png", "img2.png", "img1.png");
echo "Standard string comparison
";
usort($arr1, "strcmp");
print_r($arr1);
echo "
Natural order string comparison
";
usort($arr2, "strnatcmp");
print_r($arr2);
?>
The above example will output:
Standard string comparison
Array
(
[0] => img1.png
[1] => img10.png
[2] => img12.png
[3] => img2.png
)
Natural order string comparison
Array
(
[0] => img1.png
[1] => img2.png
[2] => img10.png
[3] => img12.png
)
