不区分大小写的排序数组 [英] Case insensitive sort array

问题描述

前段时间找上阵列线程排序我想出了以下内容：

Some time ago looking on the threads on array sorting I had come up with the following:

public function sortList(&$objects, $on, $order = 'ASC') {
    $comparer = ($order === 'DESC') 
    ? "return -strcmp(\$a->{$on},\$b->{$on});" 
    : "return strcmp(\$a->{$on},\$b->{$on});"; 
usort($objects, create_function('$a,$b', $comparer)); 
return $objects;
}

以上code工作得很好，唯一的问题是，它是区分大小写的，而我想它是区分大小写。
这将无需重写整个事情可能吗？

The above code works fine, the only problem is that it is case sensitive, whereas I'd like it to be case insensitive. Would it be possible without rewriting the whole thing?

推荐答案

使用 strcasecmp 代替STRCMP的

Use strcasecmp instead of strcmp.
