$s = '000000001';
echo trim(preg_replace('/^\d{1,3}
------解决方案--------------------
\d{2}/', '$0/', $s), '/');
000/00/00/01
------解决方案--------------------
$s='000000001';
$array=array();
$array[]=substr($s,0,3);
$array[]=substr($s,3,2);
$array[]=substr($s,5,2);
$array[]=substr($s,7,2);
echo implode('/',$array);
