php-html 动态表格分行-数据结构剖析

$files = scandir('.');
echo '<table align="center" border="1" cellpadding="5" cellspacing="0" width="800" style="min-width:444px;">';
$counter = 1;
$each_columns = 4;
foreach($files as $file_num => $file) {
	if($file_num > 1){
		$file = iconv("GBK","UTF-8",$file);  //或者 iconv("gb2312","UTF-8",$value);
		if(is_dir($file)){
			$file = '<a href="'.$file.'">'.$file.'</a>';
			if($counter % $each_columns == 1) {
				echo '<tr>';
			}
			echo '<td>'.$counter.$file.'</td>';
			if($counter % $each_columns == 0){
				echo '</tr>';
			}
			$counter++;
		}
	}
}
$counter = $counter-1;
if($counter % $each_columns != 0){
	for($i = 0; $i < ($each_columns-($counter)%$each_columns); $i++){
		echo "<td>&nbsp;</td>";
	}
}
echo '</table>';
