Question

我在var中保存了一个字符串值，我想将它与数组进行比较并打印最接近匹配的数组编号，同时区分大小写。

所以问题是我如何在我的数组中找到最接近的匹配$bio，在这种情况下，它将 4

我见过pregmatch，但我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)

{

}

我在思考像思考

$matches  = preg_grep ($bio, $list);

print_r ($matches);

Answer 1

这可能是similar text的工作，即：

$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

使用max

的另一种方法

$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";

<强>输出：

Best match is at index: 4 with score: 3
