In a natural algorithm, the number 2 is less than the number 10. In computer sorting, 10 is less than 2, because the 编程客栈first number in "10" is less than 2.
在“自然运算法则”中,2比10小。在计算机序列当中,10比2小,因为“10”中的第一个数字是“1”,它小于2。
This function returns:
这个函数将返回下列值:
•0 - if the two strings are equal
0 – 如果字符串编程客栈相等
•<0 - if string1 is less than string2
<0 – 如果string1小于string2
•>0 - if string1 is greater than stri编程客栈ng2
>0 – 如果string1大于string2
Syntax
语法
strnatcmp(string1,string2)
Parameter参数 | Description描述 |
---|---|
string1 | Required. Specifies the first string to compare 必要参数。指定参与比较的第一个字符串对象 |
string2 | Required. Specifies the second s编程客栈tring to compare 必要参数。指定参数比较的第二个字符串对象 |
Tips and Notes
注意点
Note: The strnatcmp() is case-sensitive.
注意:strnatcmp()函数是区分大小写的。
