這篇文章主要是對(duì)php中strnatcmp()函數(shù)的用法進(jìn)行了詳細(xì)的總結(jié)介紹,需要的朋友可以過來(lái)參考下,希望對(duì)大家有所幫助。
Definition and Usage
定義和用法
The strnatcmp() function compares two strings using a "natural" algorithm.
strnatcmp()函數(shù)的作用是:用自然運(yùn)算法則比較字符串(大小寫敏感)。
In a natural algorithm, the number 2 is less than the number 10. In computer sorting, 10 is less than 2, because the first number in "10" is less than 2.
在“自然運(yùn)算法則”中,2比10小。在計(jì)算機(jī)序列當(dāng)中,10比2小,因?yàn)?ldquo;10”中的第一個(gè)數(shù)字是“1”,它小于2。
This function returns:
這個(gè)函數(shù)將返回下列值:
•0 - if the two strings are equal
0 – 如果字符串相等
•<0 - if string1 is less than string2
<0 – 如果string1小于string2
•>0 - if string1 is greater than string2
>0 – 如果string1大于string2

Tips and Notes
注意點(diǎn)
Note: The strnatcmp() is case-sensitive.
注意:strnatcmp()函數(shù)是區(qū)分大小寫的。
Example
案例代碼如下:
- <?phpecho strnatcmp("2Hello world!","10Hello world!");echo "<br />";echo strnatcmp("10Hello world!","2Hello world!");?>
The output of the code above will be:
