strnatcasecmp
(PHP 4, PHP 5)
strnatcasecmp — Case insensitive string comparisons using a "natural order" algorithm
说明
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. For more information see: Martin Pool's » Natural Order String Comparison page.
参数
- str1
-
The first string.
- str2
-
The second string.
返回值
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.
