从锁定到ID的多维数组中获取特定值

也许这个标题有点让人困惑，但让我试着解释一下。

我有一个数据库(informix)，并使用PHP PDO，在该数据库中有一个包含页面样式表的表。如下所示:

特殊的ID，完整的样式表(就像我们在CSS文件中那样)。

现在我可以在多维数组中显示记录(参见下面的代码和输出):

$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>";

输出:

现在我要做的是，从每个ID(如:TXT-633-P1B1)中获取以下样式:

font =宋体;font - family:宋体;左:0 px; .

并将它们存储到结果中，以便在需要时重用和回显它们。

在这种情况下，我应该得到4个ID和4个样式项(包括amount px)。

有人知道怎么做吗?我希望我的问题解释正确。

感谢

谢谢你的帮助，我有一个问题。

如何将这些值添加到预制div中?例如:

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

对于数组中的每个ID

我真的很感激。

试试这个:

$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;
}

生产(new_styles美元):

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
        )
)

编辑:根据OP的要求，我在我的回答中添加了更多内容。要在内容中使用这些样式，你可以这样做:

$content = '';
foreach($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";
}

将$content设置为:

<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>
