php - 在php代码中添加mysql查询项

Question

我正在使用下面的代码来运行灯箱功能。它工作正常，但我需要更改 - lightbox_display('properties/593/', 'lightbox[gallery]'); 的最后一行以使用 $propertyimagefolder 而不是 593。我尝试了 lightbox_display('properties/$propertyimagefolder/', 'lightbox[gallery]'); 但没有运气。谁能帮忙解决这个问题吗？

$propertyimagefolder = $row['Reference_No'];

    function lightbox_display($dir_to_search, $rel){
        $image_dir = $dir_to_search;
        $dir_to_search = scandir($dir_to_search);
        $image_exts = array('gif', 'jpg', 'jpeg', 'png');
        $excluded_filename = '_t';

            foreach ($dir_to_search as $image_file){
            $dot = strrpos($image_file, '.');
            $filename = substr($image_file, 0, $dot);
            $filetype = substr($image_file, $dot+1);
            $thumbnail_file = strrpos($filename, $excluded_filename);
                if ((!$thumbnail_file) and array_search($filetype, $image_exts) !== false){

echo "<a href='../../".$image_dir.$image_file."' rel='".$rel."'><img src='../../".$image_dir.$filename.".".$filetype."' alt='".$filename."' width='100' height='80' title=''/></a>"."\n";

                }
            }
    }

    lightbox_display('properties/593/', 'lightbox[gallery]');

PHP 不处理单引号中的变量字符串。只需替换为双引号即可:

lightbox_display("properties/$propertyimagefolder/", 'lightbox[画廊]');

或者连接变量和字符串:

lightbox_display('properties/' . $propertyimagefolder . '/', 'lightbox[gallery]');
