Question

我有这个PHP函数：

**original content**
<html>
<body>
    <!-- somthing text <a href="google.com" >google</a> somthing
    asdf
    asdfasdf
    asdfasdfs
    -->

    <!-- somthing text <a href="google.com" >google</a> somthing
    asdf<!--
    asdfasdf
    asdfasdfs
    -->
    <a href="yahoo.com">yahoo</a>   
</body>
</html>

**Expected Content**
<html>
<body>
    <!-- somthing text ^^ href="google.com" >google</a> somthing
    asdf
    asdfasdf
    asdfasdfs
    -->

    <!-- somthing text ^^ href="google.com" >google</a> somthing
    asdf<!--
    asdfasdf ^^ href="google.com" >google</a>
    asdfasdfs
    -->
    <a href="yahoo.com">yahoo</a>   
</body>
</html>

当我执行

public function addInvoice ($order_id, $invoice_id, $product_id, $product_quantity, $product_price, $product_reseller_fee, 
                            $product_reseller_poin, $product_referral_fee, $product_referral_id, 
                            $product_vendor_sales, $custom_invoice){

    $this->connect();

    $this->select('shopping_cart', 'courier_cost', NULL, 'product_id = "'.$product_id.'" AND order_id = "'.$order_id.'"', NULL, '1');
    $ongkir = $this->getResult();
    $ongkir = $ongkir[0]['courier_cost'];           //-- this gives me ZERO when inserted into MySQL
    $product_vendor_income = ($product_vendor_sales * $product_quantity) + $ongkir;     //-- $ongkir in this formula also count as ZERO

    $data = array ('order_id' => $this->escapeString($order_id),
                   'invoice_id' => $this->escapeString($invoice_id),
                   'product_id' => $this->escapeString($product_id),
                   'product_quantity' => $this->escapeString($product_quantity),
                   'product_price' => $this->escapeString($product_price),
                   'product_reseller_fee' => $this->escapeString($product_reseller_fee),
                   'product_reseller_poin' => $this->escapeString($product_reseller_poin),
                   'product_referral_fee' => $this->escapeString($product_referral_fee),
                   'product_referral_id' => $this->escapeString($product_referral_id),
                   'product_vendor_sales' => $this->escapeString($product_vendor_income),
                   'custom_invoice' => $this->escapeString($custom_invoice));

    $this->insert('sales_invoice', $data);
    $res = $this->getResult();
    return $res;
}

时，

$ongkir变量结果为string(4) "6000"。所以，我相信它是一个字符串。

另一方面，我有一个MySQL列，其数据类型为var_dump。当我尝试将Decimal插入数据库时，它最终为零。

我必须将此字符串转换为数字数据类型吗？这很奇怪......

我试图在屏幕上显示$ongkir的价值：

$ongkir

它产生：

$ongkir = $product->addInvoiceCopy ('ORD - 5762 5CF0 BFB9 6', null, '801', '1', null, null, null, null, null, null, '22000', null);
$total = (100 * 2) + $ongkir;
var_dump($total);

所以，int(6200)不是空变量或零。但为什么我插入MySQL时会得到零？任何线索？谢谢。

在MySQL中插入时，此字符串变量始终为零
