PHP-查找两个文本之间的匹配单词数量?
问题描述：
我想找到两个文本之间的相似单词的数量
I want to find number of similar words between two texts
示例
$str1=the cat is on the roof
$str2=the mouse is on the roof
$ str1和$ str2中的
the，is，on，theroof 字相似
the,is,on,the,roof words are similar in $str1 and $str2
所以输出将是第5位或百分比是86％
我正在尝试类似的text()函数，但是此函数无法按我想要的方式工作.
I am try similar_text() function but this function not work as which i want.

轻松分解它们，然后使用array_diff:
Easy, explode them and then use array_diff:
$totalWords = count($array_1);
$array_1 = explode(" ", $str1);
$array_2 = explode(" ", $str2);
$differenceCount = count(array_diff($array_1, $array_2));
$differentPercent = $differenceCount / ($totalWords / 100);

上面的编辑代码以显示百分比.但是请记住，如果数组1和数组2的字数不相同，您可能会得到错误的结果.
Edited code above to display percentage. However remember you may have a wrong result if the word count of array 1 and array 2 is not identical.
