The strnatcasecmp() function compares two strings using a "natural" algorithm.In a natural algorithm, 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.
int strnatcasecmp ( string $str1 , string $str2 )
This function implements a comparison algorithm that orders alphanumeric strings in the way a human being would. The behaviour of this function is similar to strnatcmp(), except that the comparison is not case sensitive.
strnatcasecmp — Case insensitive string comparisons using a "natural order" algorithm
| Parameter | Description |
|---|---|
| str1 | The first string. |
| str2 | The second string. |
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.
