如何生成動態數字數組像下面

Question

$big_box = array(1,2,3,16,17,18,31,32,33,46,47,48,61,62,63,76,77,78,91,92,93,106,107,108,121,122,123,136,137,138............); 

$small_box = array(4,19,34,49,64.............); 

我要生成動態數字數組像上面的例子中高達10000

Answer 1

數組$big_box嘗試這樣的事情。

 $j = 0; 
     for ($i=0; $i <= 1000; $i++) { 
      if ($i!=0) { 
       $big_box[] = $i; 
       $j++; 
      } 
      if ($j == 3) { 
       $j = 1; 
       $big_box[] = $i+13; 
       $i =$i+13; 
      } 
     } 
     echo "<pre>"; 
     print_r($big_box); 

和數組$small_box

 $small_box = array(); 
     for($i=0; $i <= 1000; $i++) { 
      if ($i == 0) { 
       $small_box[$i] = 4; 
      }else{ 
       $small_box[$i] = $small_box[$i-1]+15; 
      } 
     } 
     echo "<pre>"; 
     print_r($small_box);
