PHP打印阵列项目组通过

$array = (
'item'=>'1', 
'category'=>'2', 
'item'=>'2', 
'category'=>'2', 
'item'=>'3', 
'category'=>'1', 
'item'=>'4', 
'category'=>'3' 
);

我会llike在HTML中返回，如果是可能的：PHP打印阵列项目组通过

Category 1 
- item3 
Category 2 
- item1 
- item2 
Category 3 
- item4

什么建议吗？真不知道从哪里开始做这个脚本：/

编辑真正的数组是：

array(39) { 
    [0]=> 
    object(stdClass)#50 (6) { 
    ["id"]=>

你控制阵列结构？ – Znarkus

这是PHP中不可能的数组。密钥不能碰撞。 –

@ExplosionPills有没有办法？：O – sbaaaang

我不太明白你的阵列需要组项目结构，但是这 - 希望 - 可以帮助你：

$array = array (
    '1' => array('item3'), 
    '2' => array('item1', 'item2'), 
    '3' => array('item4') 
); 

foreach($array as $id => $category) { 
    echo "Category " . $id. "<br/>"; 
    foreach($category as $item) { 
     echo $item . "<br/>"; 
    } 
}

需要首先检查数组，并创建新的数组我想：/ – sbaaaang

我知道这是无关的，请随时忽略，但似乎既然你是关于语法的强迫症，我想指出，你的使用“希望“ 是错的。请参阅http://motivatedgrammar.wordpress.com/2010/01/01/whats-wrong-with-hopefully/ –

您可以使用类别为键和项目作为值创建一个数组：

foreach ($array as $item) { 
    $itemsByCategory[$item->category][] = $item; 
}

然后你就可以像它们显示：

header('Content-Type: text/plain'); 
foreach ($itemsByCategory as $category => $items) { 
    echo $category . "\n"; 
    foreach ($items as $item) { 
     echo '- ' . $item . "\n"; 
    } 
}
