int strncmp(string $str1, string $str2, int $len)
This function is similar to strcmp(), with the difference that you can specify the (upper limit of the) number of characters from each string to be used in the comparison.
Note that this comparison is case sensitive.
Returns < 0 if
str1 is less than
str2; > 0 if
str1 is greater than
str2, and 0 if they are equal.
- string $str1: The first string.
- string $str2: The second string.
- int $len: Number of characters to use in the comparison.
