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。
