Question

我有这样的阵列:

$suppliers = array(
   Utility Warehouse  => array( Gas  => array(0,0),  Electricty  => array(0,0)),
   British Gas  => array( Gas  => array(93,124),  Electricty  => array(93,124)),
   Eon  => array( Gas  => array(93,124),  Electricty  => array(93,124))
);

如何显示以下信息:

Utility Warehouse
Gas: 0-0 Electricity 0-0

British Gas
Gas: 93-134 Electricity: 93-134

Eon
Gas: 93-124 Electricity: 93-134

可以看出所显示的数据如何与阵列中的数据相对应。我试图这样做:

foreach($suppliers as $a){
    echo $a[0];
}

But this does nothing. CONFUSED!

Answer 1

<?php 

foreach($suppliers as $supplier => $category) {
    echo $supplier .  <br /> ;
    foreach($category as $cat_name => $values_arr) {
        echo $cat_name .  :   . implode( - , $values_arr) .  <br /><br /> ;
    }
}

?>

Answer 2

你可以尝试:

foreach($suppliers as $name => $value) {
    echo $name . "<br />";
    foreach($value as $a => $price) {
        echo $a . :  . $price[0]. - .$price[1];
    }
    echo "<br /><br />";
}

Answer 3

实现你们想要的东西的法典,但我建议你比照你的购买力平价技能,因为这是一项微不足道的任务。

foreach($suppliers as $name => $data){
    echo $name .  <br/> ;
    foreach($data as $utility => $value){
        echo $utility .  :   . $value[0] .  -  . $value[1] .    ;
    }
    echo  <br/><br/> ;
}

这里可以使用简单的休养功能。我发现并作了修改,以供参考。原始来源在评论中。

function print_a($array, $level=0){
  # source: https://thisinterestsme.com/php-using-recursion-print-values-multidimensional-array/
  foreach($array as $key => $value){
    # If $value is an array.
    if(is_array($value)){
      echo str_repeat("-", $level). "<br>{$key}<br>
";
      # We need to loop through it.
      print_a($value, $level + 1);
    } else{
      # It is not an array, so print it out.
      echo str_repeat("-", $level) . "{$key}: {$value}<br>
";
    }
  }
} # END FUNCTION print_a
