私は自分のデータベースに保存したい次の配列を持っています...
$insData = array(
'uid' => $fbme['id'],
'first_name' => $fbme['first_name'],
'last_name' => $fbme['last_name'],
'email' => isset($fbme['email']) ? $fbme['email'] : '',
'link' => $fbme['link'],
'affiliations' => $networks,
'birthday' => $info[0]['birthday_date'],
'current_location' => isset($fbme['location']['name']) ? $fbme['location']['name'] : '',
'education_history' => $education,
'work' => $workInfo,
'hometown_location' => isset($fbme['hometown']['name']) ? $fbme['hometown']['name'] : '',
'interests' => $info[0]['interests'],
'locale' => $info[0]['locale'],
'movies' => $movies,
'music' => $music,
'political' => $info[0]['political'],
'relationship_status' => $info[0]['relationship_status'],
'sex' => isset($fbme['gender']) ? $fbme['gender'] : '',
'tv' => $television,
'status' => '0',
'created' => $now,
'updated' => $now,
);
私はこれを行う方法でグーグルを検索しようとしましたが、テーブルに挿入する前に配列を分割する必要があることを示す情報しか見つけることができません。これは正しいです?素朴で申し訳ありませんが、PHPは非常に新しいです。
mysqlはphpデータ型を理解しないため、mysqlに配列を直接挿入することはできません。Mysqlは、SQLのみを理解します。したがって、配列をmysqlデータベースに挿入するには、配列をsqlステートメントに変換する必要があります。これは、手動またはライブラリによって実行できます。出力はINSERT
ステートメントでなければなりません。
標準的なmysqlのinsertステートメントを次に示します。
INSERT INTO TABLE1(COLUMN1, COLUMN2, ....) VALUES (VALUE1, VALUE2..)
配列のキーに表示される列を持つfbdata
という名前のテーブルを持っている場合、この小さなスニペットで挿入できます。配列がこのステートメントに変換される方法を次に示します。
$columns = implode(", ",array_keys($insData));
$escaped_values = array_map('mysql_real_escape_string', array_values($insData));
$values = implode(", ", $escaped_values);
$sql = "INSERT INTO `fbdata`($columns) VALUES ($values)";
PHP7用の更新
PHP 5.5 mysql_real_escape_string
は非推奨になり、PHP7から削除されました。参照: Php.netの新しい手順に関するドキュメント
さまざまな方法があります...準備されたステートメントを使用した例を紹介します。
$prep = array();
foreach($insData as $k => $v ) {
$prep[':'.$k] = $v;
}
$sth = $db->prepare("INSERT INTO table ( " . implode(', ',array_keys($insData)) . ") VALUES (" . implode(', ',array_keys($prep)) . ")");
$res = $sth->execute($prep);
ここでごまかしており、最初の配列のキーがSQLテーブルの列名であると想定しています。また、PDOが利用可能であると仮定しています。詳細は http://php.net/manual/en/book.pdo.php で見つけることができます
受け入れられた答えに基づいたこれに対する私の完全な解決策を以下に示します。
使用例:
include("./assets/php/db.php");
$data = array('field1' => 'data1', 'field2'=> 'data2');
insertArr("databaseName.tableName", $data);
<?PHP
/**
* Class to initiate a new MySQL connection based on $dbInfo settings found in dbSettings.php
*
* @example
* $db = new database(); // Initiate a new database connection
* mysql_close($db->get_link());
*/
class database{
protected $databaseLink;
function __construct(){
include "dbSettings.php";
$this->database = $dbInfo['Host'];
$this->mysql_user = $dbInfo['user'];
$this->mysql_pass = $dbInfo['pass'];
$this->openConnection();
return $this->get_link();
}
function openConnection(){
$this->databaseLink = mysql_connect($this->database, $this->mysql_user, $this->mysql_pass);
}
function get_link(){
return $this->databaseLink;
}
}
/**
* Insert an associative array into a MySQL database
*
* @example
* $data = array('field1' => 'data1', 'field2'=> 'data2');
* insertArr("databaseName.tableName", $data);
*/
function insertArr($tableName, $insData){
$db = new database();
$columns = implode(", ",array_keys($insData));
$escaped_values = array_map('mysql_real_escape_string', array_values($insData));
foreach ($escaped_values as $idx=>$data) $escaped_values[$idx] = "'".$data."'";
$values = implode(", ", $escaped_values);
$query = "INSERT INTO $tableName ($columns) VALUES ($values)";
mysql_query($query) or die(mysql_error());
mysql_close($db->get_link());
}
?>
<?PHP
$dbInfo = array(
'Host' => "localhost",
'user' => "root",
'pass' => "password"
);
?>
シリアル化 配列とデータベース列にテキストが表示され、問題が解決します。
たとえば、オブジェクトを保存するために、簡単に取得できるようにします。
個人的には、配列をjson_encode(必要なエスケープなどを考慮して)し、ロット全体を適切なサイズのテキスト/ブロブフィールドに入れました。
これにより、「構造化されていない」データを簡単に保存できますが、実際のPITAを使用して検索/インデックスを作成できます。
単純なjson_decodeは、データを「展開」して配列に戻します。
私は同じ問題について検索しますが、配列をタプルとして追加しないように配列をファイルに保存したいので、関数serialize()およびunserialize()が必要になる場合があります。
これを参照してください http://www.wpfasthelp.com/insert-php-array-into-mysql-database-table-row-field.htm
$query= "INSERT INTO table ( " . implode(', ',array_keys($insData)) . ") VALUES (" . implode(', ',array_values($insData)) . ")";
データベースに配列を挿入するためにこの行を書く必要があるだけです。
implode(', ',array_keys($insData))
:すべてのキーを文字列形式として提供します
implode(', ',array_values($insData))
:すべての値を文字列形式として提供
配列データをmysql phpに挿入
配列データがあります。そのデータをデータベースに投稿したい

この質問は複雑になるかもしれませんが、きっとあなたのために仕事をするでしょう。配列の挿入だけでなく、データベースのクエリ、ファイルの更新と削除を処理する2つのクラスを作成しました。 「MySqliConnection」クラスは、db接続のインスタンスを1つだけ作成するために使用されます(新しいオブジェクトの重複を防ぐため)。

$Task->person = "John"; //magic __set() method will look for setPerson(x,y) method firs if non found will assign value as it is.
$Task->description = "John Doe is a funny guy"; //magic __set() again
$Task->task_name = "John chellange"; //magic __set() again
$test = ($Task->updateRow("ID = 5")) ? "WORKS FINE" : "ERROR"; //update cutom row with object values
echo $test;
$test = ($Task->updateRow()) ? "WORKS FINE" : "ERROR"; //update curent data loaded in object
echo $test;

次の2つの方法があります。
このような質問から学ぶための最も重要なことを忘れないでください: SQLインジェクション 。
PDO および 準備済みステートメント を使用します。
PDOのチュートリアルについては、 here をクリックしてください。
最も簡単な方法
for ($i=0; $i < count($tableData); $i++) {
$cost =$tableData[$i]['cost'];
$quantity =$tableData[$i]['quantity'];
$price =$tableData[$i]['price'];
$p_id =$tableData[$i]['p_id'];
mysqli_query($conn,"INSERT INTO bill_details (bill_id, price, bill_date, p_id, quantity, cost) VALUES ($bill_id[bill_id],$price,$date,$p_id,$quantity,$cost)");
}
function insertQuery($tableName,$cols,$values,$connection){
$numberOfColsAndValues = count($cols);
$query = 'INSERT INTO '.$tableName.' ('.getColNames($cols,$numberOfColsAndValues).') VALUES ('.getColValues($values,$numberOfColsAndValues).')';
if(mysqli_query($connection, $query))
return true;
else{
echo "Error: " . $query . "<br>" . mysqli_error($connection);
return false;
}
}
function getColNames($cols,$numberOfColsAndValues){
$result = '';
foreach($cols as $key => $val){
$result = $result.$val.', ';
}
return substr($result,0,strlen($result)-2);
}
function getColValues($values,$numberOfColsAndValues){
$result = '';
foreach($values as $key => $val){
$val = "'$val'";
$result = $result.$val.', ';
}
return substr($result,0,strlen($result)-2);
}
エスケープして挿入する最も簡単な方法:
global $connection;
$columns = implode(", ",array_keys($array_data));
$func = function($value) {
global $connection;
return mysqli_real_escape_string($connection, $value);
};
$escaped_values = array_map($func, array_values($array_data));
$values = implode(", ", $escaped_values);
$result = mysqli_query($connection, "INSERT INTO $table_name ($columns) VALUES ($values)");
$columns = implode(", ",array_keys($data));
$escaped_values = array_map(array($con, 'real_escape_string'),array_values($data));
$values = implode("', '", $escaped_values);
return $sql = "INSERT INTO `reservations`($columns) VALUES ('$values')";
