Are you sure you re not intending: implode(" ", $appArray)? Newline characters aren t actually treated as newline characters when encapsulated in single quotes .

使用PHP_EOL(线末):

implode(PHP_EOL, $array);

Actually, in single quotes means (literally), not carriage return. Try using double quotes in implode ().

Try enclosing the in double quotes.

就像他们重新被解读为两种特性一样:反弹和反射,反弹越出。

你可以尝试这样做。

  $selected = implode(",
", preg_replace( /^(.*?)$/ , " $1 ", $filters[ selected_model ]));


SELECT DISTINCT(D.model_id) AS MODEL_ID, COUNT(*) AS viewCount, t.title FROM download_logs AS D LEFT JOIN templates AS t ON D.model_id = t.id 
        WHERE D.model_type IN ( .$selected. ) GROUP BY D.model_id
