In computer sorting, 10 is less than 2, because the 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 equal0 – 如果字符串相等•0 - if string1 is less than string20 – 如果string1小于string2•0 - if string1 is greater than string20 – 如果string1大于string2Syntax语法strnatcmp(string1,string2)Parameter参数Description描述string1Required. 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string2Required. Specifies the second string 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。--------------------------------------------------------------------------------Example案例?phpecho strnatcmp(2Hello world!,10Hello world!);echo ;echo strnatcmp(10Hello world!,2Hello world!);?The output of the code above will be:上述代码将输出下面的结果-1 1
