PHP二維數組

Question

我怎樣才能使使用for循環下圖所示的二維數組：

$test = array ('D','D','D','D','C','C','D','D'); 

輸出應該是這樣的：

$output = array( 0 => array('D','D','D','D'), 1 => array('D','D')); 

感謝您的幫助。

這裏是我的代碼：

$test = array('D','D','D','D', 'C','C','D', 'D'); 
$output = array(); 
$myarray = array(); 
for ($i= 0; $i < count($test); $i++){ 
    if($test[$i] == 'D'){ 
     array_push($myarray , $test[$i]); 
    } else { 
     array_push($output,$myarray); 
    } 
} 

//OUTPUT: $output = (array(0 => array('D','D','D','D'), 1 => array('D','D','D','D'));

這可以只使用一個foreach循環來實現。

<?php 

$test = array ('D','C','D','D','D','D','C','C','D','D','C','D'); 

$temp = array(); 
$result = array(); 
foreach($test as $value){ 
    if($value != 'D' && !empty($temp)){ 
     array_push($result, $temp); 
     $temp = array(); 
    } 
    else{ 
     array_push($temp, $value); 
    } 
} 

if(!empty($temp)){ 
    array_push($result, $temp); 
} 

print_r($result);
