Question

如何遍历PHP数组这是var_export

的输出

   array (
      0 => 
      array (
        'place' => 'GreenPepper',
        'Distance' => '0.487',
        'Lat' => '8.52699',
        'Lng' => '76.92419100000006',
      ),
      1 => 
      array (
        'place' => 'BAKE \'N\' COOL',
        'Distance' => '0.513',
        'Lat' => '8.527908',
        'Lng' => '76.92643599999997',
      ),
    )

PHP

for ($row = 0; $row < sizeof($obj); $row++) {

 echo $value[$row][place];


}

它的假设输出是GreenPepper0.487，但它得到了这个

修改

原因是一个错字 echo $value[$row]['place'];而不是echo $value[$row][place];解决了问题

Answer 1

使用foreach浏览php数组

foreach ($array as $row) {
    echo $row['place'].' '.$row['Distance'].' '.$row['Lat'].' '.$row['Lng'];
}

Answer 2

你可以这样试试，

<?php

$myArray = array (
      0 => 
      array (
        'place' => 'GreenPepper',
        'Distance' => '0.487',
        'Lat' => '8.52699',
        'Lng' => '76.92419100000006',
      ),
      1 => 
      array (
        'place' => 'BAKE \'N\' COOL',
        'Distance' => '0.513',
        'Lat' => '8.527908',
        'Lng' => '76.92643599999997',
      ),
    );

foreach($myArray as $value){
    echo $value['place'] . " ";
    echo $value['Distance'] . " ";
    echo $value['Lat'] . " ";
    echo $value['Lng'] . " ";
}

?>
