将2个阵列合二为一

Question

I got 2 arrays:

  $ping_array = array();
  $ping_array[] = '400';
  $ping_array[] = '200';
  $ping_array[] = '600';
  $ping_array[] = '100';

  $timestamp_array = array();
  $timestamp_array[] = '2013-03-25 16:30:07';
  $timestamp_array[] = '2013-03-25 16:30:39';
  $timestamp_array[] = '2013-03-25 18:30:06';
  $timestamp_array[] = '2013-03-25 18:45:49';

I want to make something like this (i dont know how its called):

 $combined_array = array( 
                    'time' => $timestamp_array,
                    'ping' => $ping_array

                   );

so later on i could use the 2 arrays combined like this:

foreach ($combined_array as $ca=> $values) {
echo $values['ping'];
echo $values['time'];

}

Thx guys this combine_array is amazing

Answer 1

PHPs array_combine: "Creates an array by using one array for keys and another for its values"

$combined_array = array_combine($timestamp_array, $ping_array);

Then just repeat through similar to what you included:

foreach($combined_array as $time => $ping) {
    echo $ping;
    echo $time;
}
