與動態數組命名

Question

內陣列我怎樣才能使像從數據庫此選擇的陣列顯示：

$product_array = array(
    "1" =>array('product_id'=>'100', 'product_name'=>'Apple MacBook Pro MA464LL/A 15.4" Notebook PC','product_desc'=>'The Intel Core Duo powering MacBook Pro is actually two processors built into a single chip.', 'product_price'=>'2299.99', 'product_img'=>'products/product1.jpg'), 
    "2" =>array('product_id'=>'101', 'product_name'=>'Sony VAIO 11.1" Notebook PC','product_desc'=>'Weighing in at just an amazing 2.84 pounds and offering a sleek, durable carbon-fiber case in charcoal black. And with 4 to 10 hours of standard battery life, it has the stamina to power you through your most demanding applications.', 'product_price'=>'2699.99', 'product_img'=>'products/product6.jpg'), 
    "102" =>array('product_id'=>'102', 'product_name'=>'Canon Digital Rebel XT 8MP Digital SLR Camera','product_desc'=>'Canon EOS Digital Rebel XT SLR adds resolution, speed, extra creative control, and enhanced comfort in the hand to one of the smallest and lightest digital cameras in its class.', 'product_price'=>'550.00', 'product_img'=>'products/product3.jpg'), 
    "3" =>array('product_id'=>'103', 'product_name'=>'HTC Touch Diamond','product_desc'=>'Re-defining the perception of advanced mobile phones… the HTC Touch Diamond™ signals a giant leap forward in combining hi-tech prowess with intuitive usability and exhilarating design.', 'product_price'=>'750.00', 'product_img'=>'products/product4.jpg'), 
    "5" =>array('product_id'=>'104', 'product_name'=>'Apple iMac G5 Desktop','product_desc'=>'IMAC G5/1.8 256MB 160GB SD 20IN OS10.3', 'product_price'=>'1600.00', 'product_img'=>'products/product2.jpg'), 
    "4" =>array('product_id'=>'105', 'product_name'=>'Blackberry 8900','product_desc'=>'', 'product_price'=>'1150.00', 'product_img'=>'products/product5.jpg'), 
    "106" =>array('product_id'=>'106', 'product_name'=>'Headphone with mic','product_desc'=>'', 'product_price'=>'148.85', 'product_img'=>'products/product8.jpg')); 

這是我嘗試和其僅顯示上次內數組元素;

$getcat = mysql_query("SELECT * FROM product")or die('Error'); 
    $bk = array(); 
    $bdata = array(); 
    $data = array(); 
    while($get = mysql_fetch_array($getcat)) 
    { 
    extract($get); 
    $data[] = $get["product_id"]; 
    for($i=0;$i<= count($data);$i++){ 
    $bdata = array($i =>($bk[] = array('id'=>$product_id,'name'=>($product_name),'dew'=>$product_desc,'price'=>$product_price,'img'=>$product_img)));   } 
} 

感謝您的幫助

Answer 1

嘗試這樣，看看它是否有助於

$getcat = mysql_query("SELECT * FROM product")or die('Error'); 
    $bk = array(); 
    $bdata = array(); 
    $data = array(); 
    while($get = mysql_fetch_array($getcat)) 
    { 
    extract($get); 
    $data[] = $get["product_id"]; 
    for($i=0;$i<= count($data);$i++){ 
    $bdata[$product_id] = array($i =>array('id'=>$product_id,'name'=>($product_name),'dew'=>$product_desc,'price'=>$product_price,'img'=>$product_img));   } 
}

試試這個在表中顯示的數據：

<table border="1"> 
<thead> 
    <tr> 
     <th><b>ID</b></th> 
     <th><b>Name</b></th> 
     <th><b>Desc</b></th> 
     <th><b>Price</b></th> 
     <th><b>IMG</b></th> 
    </tr> 
</thead> 
<tbody> 
<?php 
    foreach($product_array as $product){ 
     echo "<tr>"; 
     echo "<td>" . $product["product_id"] . "</td>"; 
     echo "<td>" . $product["product_name"] . "</td>"; 
     echo "<td>" . $product["product_desc"] . "</td>"; 
     echo "<td>" . $product["product_price"] . "</td>"; 
     echo "<td>" . $product["product_img"] . "</td>"; 
     echo "</tr>"; 
    } 
?> 
</tbody> 

Answer 3

最小的代碼I ca ñ拿出去接近你所描述的$product_array是：

$getcat = mysql_query("SELECT * FROM product")or die('Error'); 
$product_array = array(); 
while($get = mysql_fetch_array($getcat); 
    $product_array[] = $get; 
vardump($product_array); 

指標是不同的，是一樣的，你試着用$bdata做什麼。

你的代碼中的錯誤是，你用覆蓋了$bdata在每一個新的數組週期。這就是爲什麼你只看到最後一個內部數組。你可以修復這樣的：

$bdata[$i] = $bk[] = array('id'=>$product_id,'name'=>($product_name),'dew'=>$product_desc,'price'=>$product_price,'img'=>$product_img); 

所有額外的數組和計數看起來對我來說效率很低。而你使用extract會使你的符號表變得混亂。
