php比较相似字符串的方法

本文实例讲述了php比较相似字符串的方法。分享给大家供大家参考。具体分析如下：

这里通过php的similar_text函数比较两个字符串的相似性。

$word2compare = "stupid";$words = array(  "stupid",  "stu and pid",  "hello",  "foobar",  "stpid",  "upid",  "stuuupid",  "sstuuupiiid",);while(list($id, $str) = each($words)){  similar_text($str, $word2compare, $percent);  print "Comparing "$word2compare" with "$str": ";  print round($percent) . "%";}/*Results:Comparing "stupid" with "stupid": 100%Comparing "stupid" with "stu and pid": 71%Comparing "stupid" with "hello": 0%Comparing "stupid" with "foobar": 0%Comparing "stupid" with "stpid": 91%Comparing "stupid" with "upid": 80%Comparing "stupid" with "stuuupid": 86%Comparing "stupid" with "sstuuupiiid": 71%*/

希望本文所述对大家的php程序设计有所帮助。
