Double array to normal array and then join :)

[lajkonik86]

My problem:

Got a double array(or whatever is the name of these things) similar to this but a hell of a lot bigger:
$searchset[0]['post_id'] = 20;
$searchset[1]['post_id'] = 40;
$searchset[0]['thread_id'] = 2;
$searchset[1]['thread_id'] = 4;

Need to make that to a normal array, tried this:
$temp = $searchset['post_id']
echo $temp[0];
Should return 20, But that doesn't work
What is the correct syntax to make $temp[0] return 20 in this example?

This would do it:

foreach ($searchset as $value) {
    $temp[] = $value['post_id'];
}
echo $temp[0];  // Echos '20'
echo $temp[1];  // Echos '40'

Those things are multidimensional arrays.

$merged = array_merge($to_merge[0], $to_merge[1]);

multidimensional, nice
My array is coming from a rather large database query, something like 130 values. Looping through each value would offcourse work, but is there a better way?

I'm not sure how array_merge would be usefull

I think you'll find the temp array will be filled before you can take a sip of coffee.

is there a better way?

echo $searchset[0]['post_id'];

okay, ill go with that then
Thanks 😃

Here's a way that's probably not any faster, but might look cooler 🙂 :

function id_to_1d($val)
{
    return $val['post_id'];
}

$temp = array_map('id_to_1D', $searchset);
echo $temp[0];  // Echos '20' 
echo $temp[1];  // Echos '40'
