最終的には、csv ファイルを mysql db にインポートするページを作成しようとしています。

csv のインポートに成功しました。そして、ユーザーがデータベースのどのフィールドがcsvのどのセクションに対応するかをドロップダウンから選択できるようにページを設定しました。

例えば

student_firstname: [First_Name] 
student_surname: [Last_Name] 
student_address1: [Street_1] 
etc.

その後、2 つの配列を作成しました。最初の配列は mysql フィールドと csv 見出しを示し、2 番目は csv ファイルからの生データです。

    Array
(
    [firstname] => First_Name
    [surname] => Last_Name
    [address1] => Street_1
    [address2] => Street_2
    [address3] => City
    [address4] => County
    [postcode] => Postcode
    [telephone] => Mobile_Phone
    [notes] => None
)
Array
(
    [0] => Array
        (
            [Username] => 
            [Last_Name] => Jacobs
            [First_Name] => Adam
            [Email] => 
            [Password] => password
            [Student_Id] => 
            [Middle_Name] => 
            [Job_Title] => 
            [Department] => 
            [Company] => 
            [Street_1] => 177 The Road
            [Street_2] => 
            [City] => Exeter
            [County] => 
            [Postcode] => EX1 1XX
            [Country] => 
            [Work_Phone] => 
            [Home_Phone] => 
            [Work_Fax] => 
            [Mobile_Phone] => 01111 1112222
            [Website] => 
            [Role] => Exeter City
        )

    [1] => Array
        (
            [Username] => 
            [Last_Name] => Miller
            [First_Name] => Adam
            [Email] => 
            [Password] => password
            [Student_Id] => 
            [Middle_Name] => 
            [Job_Title] => 
            [Department] => 
            [Company] => 
            [Street_1] => The White
            [Street_2] => 21A Some House
            [City] => Creditery
            [County] => 
            [Postcode] => EX1 1AA
            [Country] => 
            [Work_Phone] => 
            [Home_Phone] => 
                [Work_Fax] => 
                [Mobile_Phone] => 07111 112222
                [Website] => 
                [Role] => Exeter City
            )
    )

私が今やろうとしているのは、2 番目の配列の値のみを最初の配列で定義された SQL フィールドに挿入する文字列を作成することです。これにより、mySQL INSERT ステートメントに追加できます。

例えば

    INSERT INTO students (student_firstname, student_surname, student_address1, student_address2, student_address3, student_address4, student_postcode, student_telephone, student_notes, student_added) VALUES 
    ('Adam','Jacobs','177 The Road','','Exeter','','EX1 1XX','01111 1112222','',''),
('Adam','Millar','The White','21A Some House','Creditory','','EX1 1AA','07111 11222','','')

私の現在のコードは、私が間違いなくうまくいっていることを示すために以下にありますが、今は混乱しています

if (isset($_POST['file_upload'])){
    $uploaded = 1;
    $lines = explode("\n", file_get_contents($_FILES["csvfile"]["tmp_name"]));
$head = str_replace(" ","_",str_getcsv(array_shift($lines)));

$array = array();
foreach ($lines as $line) {
        $row = array_pad(str_getcsv($line), count($head), '');
    $array[] = array_combine(str_replace(" ","_",$head), $row);
}


    //echo '<pre>';
    //print_r($array);
    //echo '</pre>';
    session_start();
  $_SESSION['csvimport'] = $array;
}
if (isset($_POST['submitrecords'])){
    $fields = array(
    'firstname' => $_POST['student_firstname'],
    'surname' => $_POST['student_surname'],
    'address1' => $_POST['student_address1'],
    'address2' => $_POST['student_address2'],
    'address3' => $_POST['student_address3'],
    'address4' => $_POST['student_address4'],
    'postcode' => $_POST['student_postcode'],
    'telephone' => $_POST['student_telephone'],
    'notes' => $_POST['student_notes']);

    $array = $_SESSION['csvimport'];
    echo '<pre>';
    print_r($fields);
    print_r($array);
    echo '</pre>';

    foreach ($fields as $dbfield){
        foreach(array_keys($array[0]) as $value){
        if ($dbfield == $value){
            foreach($array as $key => $value2){
                $snippet .= ",('" . $value2[$dbfield] . "','" . $studentid[0] . "','" . $studentid[1] . "')";
            }

        }



    }
}
    $snippet = substr($snippet,1);

    $insertSQL = "INSERT INTO students (student_firstname, student_surname, student_address1, student_address2, student_address3, student_address4, student_postcode, student_telephone, student_notes, student_added) VALUES $snippet";


    echo $insertSQL;

}

CSV ファイルのフィールドが含まれていなかったため、元の配列から「メモ」を削除しましたが、後で再び追加されます。

$fnames = array (
    'firstname' => 'First_Name',
    'surname' => 'Last_Name',
    'address1' => 'Street_1',
    'address2' => 'Street_2',
    'address3' => 'City',
    'address4' => 'County',
    'postcode' => 'Postcode',
    'telephone' => 'Mobile_Phone');

2 番目の array に名前を付けた後$csv、次のコードはデータベース クエリを生成します。

$db = array();
$db_cols = array_keys($fnames);
foreach ($csv as $key => $value){
    $insx = array_intersect_key($value, array_flip($fnames));
    $db[$key] = array_combine($db_cols, $insx);
    $db[$key]['notes'] = '';
    $db[$key]['added'] = '';
}
if (count($db) > 0){
    $query = "INSERT INTO students (student_";
    $query .= implode(', student_', array_keys($db[0])).") VALUES \n";
    foreach ($db as $key => $value){
        $query .= "('".implode("','", $value)."'),\n";
    }
    $query = rtrim($query, ",\n");
    echo $query;
}

出力：

INSERT INTO students (student_firstname, student_surname, student_address1, student_address2, student_address3, student_address4, student_postcode, student_telephone, student_notes, student_added) VALUES 
('Jacobs','Adam','177 The Road','','Exeter','','EX1 1XX','01111 1112222','',''),
('Miller','Adam','The White','21A Some House','Creditery','','EX1 1AA','07111 112222','','')
