将图像包括在数组中

Question

下面的代码可以很好地为pdf输出添加一个很好的页眉和页脚，但是我正在尝试向页眉和页脚添加一个图像，而不仅仅是页码等等。谢谢。

$pdf_header = array (
    'odd' => 
        array (
            'R' => 
                array (
                    'content' => '{PAGENO}',
                    'font-size' => 8,
                    'font-style' => 'B',
                    'font-family' => 'DejaVuSansCondensed',
                ),
                'line' => 1,
            ),
    'even' => 
        array (
            'R' => 
                array (
                    'content' => '{PAGENO}',
                    'font-size' => 8,
                    'font-style' => 'B',
                    'font-family' => 'DejaVuSansCondensed',
                ),
                'line' => 1,
        ),
    );
    $pdf_footer = array (
    'odd' => 
        array (
            'R' => 
                array (
                    'content' => '{DATE d.m.Y}',
                    'font-size' => 8,
                    'font-style' => 'BI',
                    'font-family' => 'DejaVuSansCondensed',
                ),
            'C' => 
                array (
                    'content' => '- {PAGENO} / {nb} -',
                    'font-size' => 8,
                    'font-style' => '',
                    'font-family' => '',
                ),
            'L' => 
                array (
                    'content' => get_bloginfo('name'),
                    'font-size' => 8,
                    'font-style' => 'BI',
                    'font-family' => 'DejaVuSansCondensed',
                ),
            'line' => 1,
        ),
    'even' => 
        array (
            'R' => 
                array (
                    'content' => '{DATE d.m.Y}',
                    'font-size' => 8,
                    'font-style' => 'BI',
                    'font-family' => 'DejaVuSansCondensed',
                ),
            'C' => 
                array (
                    'content' => '- {PAGENO} / {nb} -',
                    'font-size' => 8,
                    'font-style' => '',
                    'font-family' => '',
                ),
            'L' => 
                array (
                    'content' => get_bloginfo('name'),

                    'font-family' => 'DejaVuSansCondensed',
                ),
            'line' => 1,
        ),
    );

因此，在多维数组中，它看起来像是在存储CSS属性及其值。您是在寻找类似于‘#确定性图像’=>‘背景:url(\’imgname.ext\‘)之类的东西吗？另外，我可能会建议，不要做交替的‘偶数’和‘奇数’，试着用三值运算符做一个触发器语句。我以前做过一些事情，比如$oddeven'R‘= isset($var)？“奇数”：“偶”；这样，您就可以简单地遍历迭代数组并更改每个元素的值，而不必重复键入“偶数”或“奇数”。这会帮你节省时间。
