Combining 2 arrays into one - php

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

Try this:
$combined_array = array();
foreach ($ping_array as $key => $value){
$combined_array[] = array(
'time' => $timestamp_array[$key],
'ping' => $value
);
}

Answer 2

What about this?
for ($i=0; $i<count($timestamp_array); $i++) {
$combined_array[$i]["ping"] = $ping_array[$i];
$combined_array[$i]["time"] = $timestamp_array[$i];
}

Answer 3

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;
}

Answer 4

How about php 'array_merge_recursive'? It does exactly what you are looking for. It is found on php 4 and up.

Answer 5

What you could do is make array of objects, like this:
class PingInfo {
public $ping;
public $time;
public function PingInfo($ping, $time) {
$this->ping = $ping;
$this->time = $time;
}
}
$pingInfos = array();
$pingInfos[] = new PingInfo('400', '2013-03-25 16:30:07');
$pingInfos[] = new PingInfo('300', '2013-03-25 16:50:13');
You could build it from two array like this:
$pingInfos = array();
for ($i = 0; $i < count($ping_array); $i++)
$pingInfos[] = new PingInfo($ping_array[$i], $timestamp_array[$i]);
Now you can access it like this:
foreach ($pingInfos as $pingInfo) {
echo $pingInfo->ping;
echo $pingInfo->time;
}
