我需要用php比较这两个关键字字符串。
$original_keywords = cat, dog, mouse
$possible_keywords_1 = "cat, dog, hamster";
$possible_keywords_2 = "cat, sheep, goat";
我需要一个php脚本将数值"1"分配给第一个可能的字符串(1匹配)和"2"分配给第二个(2匹配)。有人能帮我一下吗?
$original_keywords = array("cat", "dog", "mouse");
$possible_keywords1 = preg_split('/,'s*/', "cat, dog, hamster");
echo count(array_intersect($original_keywords, $possible_keywords1))
$original_keywords = "cat, dog, mouse";
$possible_keywords_1 = "cat, dog, hamster";
$possible_keywords_2 = "cat, sheep, goat";
// Put the input keywords into an array
$keywords = explode(', ', $original_keywords);
// Put all incoming keywords into one big array (you can add as many arrays
// as you want here)
$input = array_merge(
explode(', ', $possible_keywords_1),
explode(', ', $possible_keywords_2));
// Count how many times each keywords from $input appears
$count = array_count_values($input);
// Filter out from $count any keyword that is not present in $keywords
$result = array_intersect_key($count, array_flip($keywords));
查看效果
可以使用explosion和array_intersect的组合
开头代码如下:
$possible_keywords_1_array = explode(",", $possible_keywords_1);
$possible_keywords_2_array = explode(",", $possible_keywords_2);
$matches = count(array_intersect($possible_keywords_1_array, $possible_keywords_2_array));
