  $child*$childPrice不对  乘1/3 算起来是小数
  

  <?php
  
  $manprice=5;
  $womanprice=3;
  
  for($man=1;$man<20;$man++){
  	for($woman=1;$woman<33;$woman++){
  		for($child=1;$child<100;$child++){
  			if(($man*$manprice+$woman*$womanprice+$child/3) === 100 && ($man+$woman+$child)===100){
  				echo '公鸡'.$man.'只<br>';
  				echo '母鸡'.$woman.'只<br>';
  				echo '小鸡'.(100-$man-$woman).'只<br>';
  				echo '<hr>';
  			}
  		}		
  	}
  }
