Php 我有一个数组，它是如何显示的

可以这样显示一个数组吗

$a = array(array( 'dates' => '12-11-13',
        'customer' => 'ann',
        'place' => 'EKM'),array('dates' => '12-11-13',
        'customer' => 'annex',
        'place' => 'KLM'),array('dates' => '13-11-13',
        'customer' => 'anna',
        'place' => 'PTA')
      );

因此，输出将是：

dates:12-11-13
customer:ann
place:EKM
customer:annex
place:KLM

dates:13-11-13
customer:anna
place:PTA

所以，为了给你一个更明智的答案，你首先需要做的是正确地存储数组，这样你就可以正确地对它进行迭代，看起来你的键是日期，所以你在编译数组时应该做的是将所有类似的（日期）键保存在一起

例如：

// Array Creation
$orders = array();
$orders['12-11-13'][] = array('customer' => 'ann', 'place' => 'EKM');
$orders['12-11-13'][] = array('customer' => 'annex', 'place' => 'KLM');
$orders['10-11-13'][] = array('customer' => 'alex', 'place' => 'MCD');
$orders['10-11-13'][] = array('customer' => 'ronald', 'place' => 'BK');

这只是一个使用相似键创建数组的示例

然后，您将在数组上迭代，以显示您希望它的样子

foreach($orders as $date => $order)
{
    echo "Date: {$date} \n";
    foreach($order as $data)
    {
        echo "Customer: " . $data['customer'] ."\n";
        echo "Place: " . $data['place'] ."\n";
    }

    echo "\n\n";
}

把这一切放在一起应该会给你想要的

<?php 
// Array Creation
    $orders = array();
    $orders['12-11-13'][] = array('customer' => 'ann', 'place' => 'EKM');
    $orders['12-11-13'][] = array('customer' => 'annex', 'place' => 'KLM');
    $orders['10-11-13'][] = array('customer' => 'alex', 'place' => 'MCD');
    $orders['10-11-13'][] = array('customer' => 'ronald', 'place' => 'BK');


    foreach($orders as $date => $order)
    {
        echo "Date: {$date} \n";
        foreach($order as $data)
        {
            echo "Customer: " . $data['customer'] ."\n";
            echo "Place: " . $data['place'] ."\n";
        }

        echo "\n\n";
    }
?>

单个数组
多阵列

预期输出的格式不一致。并使用

foreach

loop。感谢您的支持..但我希望此数组采用上述格式$a=array（数组（'dates'=>'12-11-13'，'customer'=>'ann'，'place'=>'EKM'）、数组（'dates'=>'12-11-13'，'customer'=>'appendment'，'place=>'KLM'）、数组（'dates'=>'13-11-13'，'customer'=>'anna'，'place'=>'PTA'）；@user3049172若要这样做，您必须迭代该数组，以使所有相似的日期合并到一个数组中。若要使其显示您想要的方式，请执行以下操作。

$ php test.php 
Date: 12-11-13 
Customer: ann
Place: EKM
Customer: annex
Place: KLM


Date: 10-11-13 
Customer: alex
Place: MCD
Customer: ronald
Place: BK

Single Array

 <?php

  $test=array("data1","data2","data3");

  echo "I like " . $test[0] . ", " . $test[1] . " and " . $test[2] . ".";

 ?>

Multiple Array
<?php

 $test=array("teatdata"=>"testdata","testdata1"=>array("testinnderarraydata"=>"data"));
 echo $test['testdata1']['testinnderarraydata'];

?>
