php比较相似字符串的方法

前端技术 2023/09/06 PHP

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) . \"%\\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%
*/

希望本文所述对大家的php程序设计有所帮助。
