The strnatcmp() 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 strnatcmp ( string $str1 , string $str2 )
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.
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.
