Question

也许标题有点令人困惑，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。看到这样：

特殊ID，完整的样式表（就像我们在CSS文件中制作的那样）。

目前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：

Array

        [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;

现在我尝试做的是，从每个ID（如：TXT-633-P1B1）获取以下样式：

高度：75px;，宽度：793px;，顶部：0px;并离开：0px;。

并将它们存储到结果中，以便我可以在需要时重复使用并回显它们。

在这种情况下，我应该得到4个带有4个样式项目的ID（包括数量px）。

有没有人知道如何做到这一点。我希望我能正确地解释我的问题。

由于

感谢非常有帮助，我确实有一个问题。

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>

这就是该数组中的每个ID。

谢谢，我真的很感激。

Answer 1

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;
}

生成（$ 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
        )

)

编辑：根据OP的要求，我在答案中添加了更多内容。要在内容中使用这些样式，您可以执行以下操作：

$content = '';
foreach($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>
