建立MySQL查詢與forearch環PHP

Question

價值觀是一個multidimenssional陣列內等：

Array ( 
    [0] => Array (
     [fname] => CollectiveAccess 
     [lname] => Administrator 
     [username] => administrator 
     ) 
    [1] => Array (
     [fname] => Jorge 
     [lname] => Ghelman 
     [username] => jorgeghe 
     ) 
    [2] => Array (
     [fname] => Sebastian 
     [lname] => Scarano 
     [username] => sscarano 
     ) 
) 

這是循環我用它來構建查詢：

foreach ($user_names as $value) { 
    foreach ($value as $value2) { 
     echo $value2 . " "; //prints all values 
     $query = "INSERT INTO users (username, fname, lname) 
        VALUES ('$value2',);"; 
    } 
} 

的print_r（$查詢）顯示，只有$ value2中的最後一個值被傳遞給查詢。

INSERT INTO users (username, fname, lname) VALUES ('test1',); 

我敢肯定這是一個新手的錯誤，但無法弄清楚。 感謝

試試這個

foreach ($user_names as $value) { 
    $query = "INSERT INTO users (username, fname, lname) 
       VALUES ('{$value['username']}', '{$value['fname']}', '{$value['lname']}');"; 
    echo $query; 
}
