從multidimentional數組獲取特定值鎖定爲ID

Question

也許標題有點混淆，但讓我試着解釋一下。

我有一個數據庫（informix），並使用PHP PDO，在該數據庫中有一個包含頁面樣式表的表。 看到這樣的：

特殊ID，完整的樣式表（就像我們在一個CSS文件中）。

此刻，我可以顯示一個多維數組的記錄（見代碼和輸出如下）：

$query = $db -> prepare("select alpb_box_id, alpb_style::lvarchar as STYLESHEET 
from ao_link_page_boxes WHERE alpb_li_id = 633 AND alpb_lngcode = '031' AND 
alpb_pageno = 1"); 

$query -> execute(); 

$result = array(); 

while($row = $query->fetch(PDO::FETCH_ASSOC)) { 

$result[] = $row; 
} 
$db = null; 

echo "<pre>"; 
print_r($result); 
echo "</pre>"; 

和輸出：

Array 
(
[0] => Array 
(
[ALPB_BOX_ID] => TXT-633-P1B1 
     [STYLESHEET] => background-attachment:scroll; background-color:rgba(0, 0, 0, 0); background-image:none; background-position:0% 0%; background-repeat:repeat; border-bottom-color:rgb(0, 0, 0); border-bottom-style:none; border-bottom-width:0px; border-collapse:separate; border-left-color:rgb(0, 0, 0); border-left-style:none; border-left-width:0px; border-right-color:rgb(0, 0, 0); border-right-style:none; border-right-width:0px; border-top-color:rgb(0, 0, 0); border-top-style:none; border-top-width:0px; bottom:auto; box-shadow:none; caption-side:top; color:rgb(0, 0, 0); font-family:Swis721 BT; font-size:69px; font-style:normal; font-variant:normal; font-weight:normal; height:75px; left:0px; letter-spacing:normal; line-height:normal; list-style-image:none; list-style-position:outside; list-style-type:disc; margin-bottom:0px; margin-left:0px; margin-right:0px; margin-top:0px; max-height:none; max-width:none; min-height:0px; min-width:0px; overflow-x:hidden; overflow-y:hidden; padding-bottom:0px; padding-left:0px; padding-right:0px; padding-top:0px; position:relative; right:auto; text-align:-webkit-auto; text-decoration:none; text-indent:0px; text-overflow:clip; text-transform:none; top:0px; vertical-align:baseline; white-space:normal; width:793px; word-spacing:0px; z-index:auto;

現在我嘗試做的是，從每個ID（例如：TXT-633-P1B1）中獲得以下樣式：

height：75px; width：793px; top：0px;和left：0px ;.

並將它們存儲到結果中，以便在需要時可以重複使用並回顯它們。

在這種情況下，我應該得到4個ID的4個樣式項目（包括數量px）。

有沒有人有一個想法如何做到這一點。 我希望我解釋我的問題是正確的。

感謝

感謝，這是非常有益的，我有一個問題。

如何將這些值添加到預製的div中。 例如：

<div id="TXT-633-P1B1" style="height:75px; width:793px; top:0px; left:0px;"></div> 

而這對於每個ID，它是該陣列英寸

謝謝，我真的很感激。

Answer 1

試試這個：

$new_styles = array(); 
$styles_to_collect = array('height', 'width', 'top', 'left'); 
foreach($result as $r) 
{ 
     $new_entry = array(); 
     foreach($styles_to_collect as $stc) 
     { 
       preg_match('/[;\s]\s*'.$stc.':\s*([\d]+(px)?)([;\s]|$)/', $r['STYLESHEET'], $matches); 
       $new_entry[$stc] = $matches[1]; 
     } 
     $new_styles[$r['ALPB_BOX_ID']] = $new_entry; 
} 

產生（$ new_styles）：

Array 
(
    [TXT-633-P1B1] => Array 
     (
      [height] => 75px 
      [width] => 793px 
      [top] => 0px 
      [left] => 0px 
     ) 

    [TXT-633-P1B2] => Array 
     (
      [height] => 197px 
      [width] => 717px 
      [top] => 75px 
      [left] => 0px 
     ) 

    [IMG-633-P1B3] => Array 
     (
      [height] => 188px 
      [width] => 377px 
      [top] => 207px 
      [left] => 0px 
     ) 

    [IMG-633-P1B4] => Array 
     (
      [height] => 188px 
      [width] => 377px 
      [top] => 0px 
      [left] => 0px 
     ) 

) 

編輯：每任擇議定書的要求我加入更多我的答案。 要使用這些樣式的內容，你可以這樣做：

$content = ''; 
foreach($new_styles as $id=>$ns) 
{ 
     $inline_styles = ''; 
     foreach($ns as $name=>$value) $inline_styles .= $name.': '.$value.'; '; 
     $inline_styles = trim($inline_styles); 
     $content .= '<div id="'.$id.'" style="'.$inline_styles."\"></div>\n"; 
} 

將設置$內容：

<div id="TXT-633-P1B1" style="height: 75px; width: 793px; top: 0px; left: 0px;"></div> 
<div id="TXT-633-P1B2" style="height: 197px; width: 717px; top: 75px; left: 0px;"></div> 
<div id="IMG-633-P1B3" style="height: 188px; width: 377px; top: 207px; left: 0px;"></div> 
<div id="IMG-633-P1B4" style="height: 188px; width: 377px; top: 0px; left: 0px;"></div>
