Question

 $stringitem2= soap|2|15|30&soap|1|5|10&soap|20|150|300 



$array = explode('&', $stringitem2);
    // Now explode each on ,
    foreach ($array as &$substring) {
        $substring = explode('|', $substring);
        echo $substring[0]; 
    echo "<br/>";
    echo  $substring[1]; 
    echo "<br/>";
    echo $substring[2];
    echo "<br/>";
    echo $substring[3];
    }

在这里，我正在使用foreach循环

爆炸一个在first和substring explodes中定义的字符串

我的输出是

soap
2
15
30
soap
1
5
10
soap
20
150
300

我正在使用以下代码将数据插入数据库...

$bill_no = $stringnew[2];
 $bill_amount = $stringtotal[1];
 $item_name = $substring[0];
$quantity = $substring[1];
 $rate = $substring[2];
 $amount = $substring[3];
$discount = $stringtotal[0];

try {
    $dbh = new PDO('mysql:host=' . DB_SERVER . ';dbname=' . DB_NAME . '', DB_USER, DB_PASS);
    $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $dbh->setAttribute(PDO::ATTR_CASE, PDO::CASE_LOWER);
} catch (PDOException $e) {
    echo $e->getMessage();
    die();
}




try {
    $query = $dbh->prepare("INSERT INTO billing (bill_no, bill_amount, item_name, quantity, rate, amount, discount) VALUES (:bill_no, :bill_amount, :item_name, :quantity, :rate, :amount, :discount);");
    $query->setFetchMode(PDO::FETCH_ASSOC);
    $query->execute(array(
            "bill_no" => $bill_no, 
           "bill_amount" => $bill_amount,
           "item_name" => $item_name,
           "quantity" => $quantity,
            "rate" => $rate,
            "amount" => $amount,
           "discount" => $discount
          ));
} catch (PDOException $ex) {
    echo $ex->getMessage();
}

当我发送输入时，它的最终值仅插入到表格中......

我想插入item_name, quantity, rate, amount,这四个值正在循环...

soap ---insert into item_name
2    ---insert into quantity
15   ---insert into rate
30   ---insert into amount
soap ---insert into item_name
1    ---insert into quantity
5    ---insert into rate 
10   ---insert into amount
soap ---insert into item_name
20   ---insert into quantity
150  ---insert into rate 
300   ---insert into amount
.............................
.............................
.............................
.............................

循环可能会变长很长一段时间...我希望将上述值作为循环插入到相关字段中，如上所述......通过使用上面的mysql插入查询，它只取最后一个循环值...如何插入所有值。 ...

注意：除了这四个item_name, quantity, rate, amount,剩下的东西不在循环中，它们自己得到一个值...

Answer 1

我已经简化了数组中的代码，您可以使用简单的foreach

轻松实现值

$stringitem2= 'soap|2|15|30&soap|1|5|10&soap|20|150|300';
$string_arr = array('item_name', 'quantity', 'rate', 'amount');
$result = array();
foreach(explode('&',$stringitem2) as $key => $value){
    $result[$key] = array_combine($string_arr,explode('|',$value));
}
print_r($result);//Array ( [0] => Array ( [item_name] => soap [quantity] => 2 [rate] => 15 [amount] => 30 ) [1] => Array ( [item_name] => soap [quantity] => 1 [rate] => 5 [amount] => 10 ) [2] => Array ( [item_name] => soap [quantity] => 20 [rate] => 150 [amount] => 300 ) )

Answer 2

试试这个

   //Place inside loop
    $values[] = "($bill_no, $bill_amount, $item_name, $quantity, $rate, $amount, $discount)";
// place this code after loop
try{
    $params = implode(",", array_fill(0, count($values), "?"));
    $query = $dbh->prepare("INSERT INTO billing (bill_no, bill_amount, item_name, quantity, rate, amount, discount) VALUES (".$params.")");
    $query->setFetchMode(PDO::FETCH_ASSOC);
    $query->execute($values);
} 
} catch (PDOException $ex) {
    echo $ex->getMessage();
}

字符串爆炸，然后子串爆炸使用foreach循环然后使用PHP插入数据库
