php比較相似字串的方法_php技巧

本文執行個體講述了php比較相似字串的方法。分享給大家供大家參考。具體分析如下：

這裡通過php的similar_text函數比較兩個字串的相似性。

$word2compare = "stupid";$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) . "%\n";}/*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%*/

希望本文所述對大家的php程式設計有所協助。
