查找与数组php最近的匹配字符串

我有一个保存在var中的字符串值，我想将它与数组进行比较，并打印最接近的匹配数组号，同时区分大小写

因此，问题是如何在数组中找到与var

$bio

最近的匹配项，在这种情况下，它将是4

我看过pregmatch，但不确定在这种情况下如何使用它

我有代码

<?php
$bio= "Tom, male, spain";

$list= array(
    1 => array("Tom", "male", "UK"),
    8 => array("bob", "Male", "spain"),
    4 => array("Tom", "male", "spain"),
    9 => array("sam", "femail", "United States")
);

function best_match($bio, $list)

{

}

这可能是一份工作，即：

另一种使用

输出：

Best match is at index: 4 with score: 3

最接近的匹配基于什么？好点我会更新问题这看起来很有希望，谢谢我会尽快尝试接受答案

$bio= "Tom, male, spain";

$list = array(
    1 => array("Tom", "male", "UK"),
    8 => array("bob", "Male", "spain"),
    4 => array("Tom", "male", "spain"),
    9 => array("sam", "femail", "United States")
);

$percent_old = 0;
foreach ($list as  $key => $value ) # loop the arrays
{
    $text = implode(", ", $value); # implode the array to get a string similar to $bio
    similar_text($bio, $text, $percent); # get a percentage of similar text

    if ($percent > $percent_old) # check if the current value of $percent is > to the old one
    {
        $percent_old = $percent; # assign $percent to $percent_old
        $final_result = $key; # assign $key to $final_result
    }
}

print $final_result;
# 4

$bio= "Tom, male, spain";

$list= array(
    1 => array("Tom", "male", "UK"),
    8 => array("bob", "Male", "spain"),
    4 => array("Tom", "male", "spain"),
    9 => array("sam", "femail", "United States")
);

function best_match($bio, $list) {
    $arrbio = explode(', ', $bio);
    $max = 0;
    $ind = 0;
    foreach($list as $k => $v) {
        $inter = array_intersect($arrbio, $v);
        if (count($inter) > $max) {
            $max = count($inter);
            $ind = $k;
        }
    }
    return [$ind, $max];
}
list($index, $score) = best_match($bio, $list);
echo "Best match is at index: $index with score: $score\n";

Best match is at index: 4 with score: 3
