该函数实现了以人类习惯对数字型字符串进行排序的比较算法。除了不区分大小写，该函数的行为与 <span class="function"><a href="strnatcmp.html" class="function">strnatcmp()</a></span> 类似。更多信息，参见：Martin Pool 的<a href="http://sourcefrog.net/projects/natsort/" class="link external">» 自然顺序的字符串比较</a>页面。

与其他字符串比较函数类似，如果 <code class="parameter">str1</code> 小于

<code class="parameter">str2</code> 返回 < 0；

如果 <code class="parameter">str1</code>
|

大于 <code class="parameter">str2</code>

返回 > 0；如果两者相等，返回 0。
