如何在php中过滤类似的字符串？

Question

这是我的例子：

$string1 = "I love php coding and want to get some help";
$string2 = "I like java coding and like to help other people" ;
$output = anyfunction($string1, $string2);

我希望得到输出= 我编码和帮助

php中是否有内置函数来执行此任务？

试试这个： -

<?php
$string1 = "I love php coding and want to get some help";
$string2 = "I like java coding and like to help other people" ;
  function getCommonCharacter($str1,$str2,$case_sensitive = false)
  {
    $ary1 = explode(' ',$str1);
    $ary2 = explode(' ',$str2);

    if ($case_sensitive)
    {
      $ary1 = array_map('strtolower',$ary1);
      $ary2 = array_map('strtolower',$ary2);
    }

    echo (implode(' ',array_intersect($ary1,$ary2)));
  }
  getCommonCharacter($string1,$string2,$case_sensitive = false);
  ?>

输出： - http://prntscr.com/746ewy

注意： - 区分大小写为false，以匹配小写或大写。你可以改变以查看其他结果。谢谢。
