如何在PHP中将分钟除以3？

Question

如何将时间除以3？$minute%3==0如果分钟是0,3,9,12,15,我知道 可以工作......

但是如何判断分钟是否为1,4,10,13,16,如果分钟是2,5,11,14,17？

谢谢.

$minute = date('i');
if($minute%3==0){
  //if minute is 0,3,9,12,15...do something
}else if($minute%3+1==0){
  //if minute is 1,4,10,13,16...do something
}else if($minute%3+2==0){
  //if minute is 2,5,11,14,17...do something
}

通过检查除以3的余数来做到这一点:

$minute = date('i');
if($minute%3==0){
  //if minute is 0,3,9,12,15...do something
}else if($minute%3==1){
  //if minute is 1,4,10,13,16...do something
}else if($minute%3==2){
  //if minute is 2,5,11,14,17...do something
}
