My array is like: (Below is the dump extract) 

array(3) { 
    [0]=> array(2) { 
        [0]=> string(4) "0013" 
        [1]=> float(28.936563322435) 
    } 
    [1]=> array(2) { 
        [0]=> string(4) "0003"
        [1]=> float(35.514521271921) 
    } 
    [2]=> array(2) { 
        [0]=> string(4) "0007" 
        [1]=> float(47.577230340278) 
    }

I would like to extract its 1st value like 0013 or 0007 etc into a variable say $order such that the final result is something like this

$order= "0013,0003,0007";

I tried to do something like this:

foreach($array as $x){
    $order = x[0].",";
    }

BUT it only extracts the first element

To achieve what you desire you can use

$order = implode(',', array_column($array, 0));

You can do it using array_map() and implode():

$order = implode(',', array_map(function($a) { return $a[0]; }, $array));
// string '0013,0003,0007' (length=14)

Or, if you're using PHP 5.5 or above:

$order = implode(',', array_column($array, 0));

for($i=0; $i<count($array); $i++){
    $res[$i]=$array[$i][0];
}
$order=implode(",", $res);

This will give you a string with the first values of your nested arrays, all comma-separated.

$arr = array();
foreach($a as $k=>$v){
    $arr[] = $v[0];
}
$order = implode(',', $arr);
