# strncmp

(PHP 4 >= 4.0.0)

strncmp -- Binary safe string comparison of the first n characters

## Description

``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 (`len`) from each string to be used in the comparison. If any of the strings is shorter than `len`, then the length of that string will be used for the comparison.

Returns < 0 if `str1` is less than `str2`; > 0 if `str1` is greater than `str2`, and 0 if they are equal.

Note that this comparison is case sensitive.
