我有一个字符串数组（如示例所示）。我只是想知道他们当中最常见的是什么。最常见的字符串定义为：-如果Apple Ipod touch出现10次（比如），而Apple Ipod出现8次，那么我会说Apple Ipod touch在所有元素中都是主导/常见的字符串。

那么，有人能给我推荐一些好的算法吗？问题是我没有任何标准/基准可供比较。我只需要将所有元素相互比较，找出最常见的元素。这必须在PHP或Javascript中实现。
希望我的问题很清楚。如果我不清楚，请评论。
我不确定您是否看过使用PHP的similar_text函数，或者是否有类似的javascript函数。谷歌的快速搜索也显示了我http://cambiatablog.wordpress.com/2011/03/25/algorithm-for-string-similarity-better-than-levenshtein-and-similar_text/
EDIT:类似的文本Javascript函数！http://phpjs.org/functions/similar_text:902
