## 例

`

     int strcoll ( string $str1 , string $str2 )

`

## 説明

Note that this comparison is case sensitive, and unlike strcmp() this function is not binary safe. strcoll() uses the current locale for doing the comparisons. If the current locale is C or POSIX, this function is equivalent to strcmp().

## 戻り値

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