php 字符串固定长度，不够补充其他字符串 

（笔记）
1 // str_pad(带填补的字符串,填补后的长度，填补字符串，填补位置)
2  $result=["7","6","8","4","3","23","27","9","5","19","10","21"];
3  if($result){
4     foreach ($result as $key => $value){
5         $result[$key]=str_pad($value,2,0,STR_PAD_LEFT);
6     }
7  //$result =["07","06","08","04","03","23","27","09","05","19","10","21"]
