$plotis = Array();
$aukstis = Array();

for($i=0; $i<count($mainArray); $i++)
{
    $plotis[] = $mainArray[$i]['plotis'];
    $aukstis[] = $mainArray[$i]['aukstis'];
}

print_r($plotis); //to display plotis array
print_r($aukstis); //to display aukstis array

What you have is a multi-dimensional array. To access the values inside the array, you need to loop through them. For this purpose, we can use the very handy foreach construct.

The basic syntax is as follows:

foreach (array_expression as $key => $value { 
    # code ...
}

In this case, the code would be:

$plotis = $aukstis = array(); // Initialize both of them as empty arrays

foreach ($array as $sub) {
    $plotis[]  = $sub['plotis'];   // Push the values to
    $aukstis[] = $sub['aukstis'];  // respective arrays
}

Of course, this can be shortened down to fewer lines of code with array_map() and the like, but since you said you're a beginner, I thought it'd be a good idea to use a plain simple foreach so you could understand it easier.

You can use array_map for this..

$plotis_arr  = array_map(function ($v){ return $v['plotis'];},$yourarray);
$aukstis_arr = array_map(function ($v){ return $v['aukstis'];},$yourarray);
