PHP array in array - DXF script

Question

I found a php script to write DXF file based on coordinates of polygon. IT works on the test file with this code (for polygon):

$d->append(new DxfPolyLine(array('points'=>array(array(1, 1),
                                        array(20, 10), 
                                        array(20, 20), 
                                        array(1, 15)),
                            'lineType'=>'DASHED',
//                          'layer' => 'DXFWRITER',
                            'flag' => 0
                            //'width' => 1,
                            //'color'=>1
                            )
));

The DXF file result is like this:

VERTEX
8
0
6
DASHED
10
20.000
20
20.000
0
VERTEX
8
0
6
DASHED
10
1.000
20
15.000
0

A lot of vertex's inside a polyline. Now I am trying to insert my own coordinates. I have the coordinates but how can I write an array in that array? I have this: $g=array_merge($g,array(array($coord[$z]*3.527785, $coord[$z+1]*3.527785))); With this code the result is:

    Array ( [0] => Array ( [0] => -133.92170714209 [1] => -41.834100838885 ) [1] => Array ( [0] => -135.19600658422 [1] => -44.558002415365 ) [2] => Array ( [0] => -173.40700872797 [1] => -25.465001344078 ) [3] => Array ( [0] => -211.44500829533 [1] => -6.4740001788315 ) [4] => Array ( [0] => -209.93490817601 [1] => -3.255100166471 ) [5] => 
Array ( [0] => -190.0770099388 [1] => -13.202000524885 ) [6] => Array ( [0] => -171.92300716209 [1] => -22.296000898041 ) [7] => Array ( [0] => -172.13500940166 [1] => -22.749000947663 ) [8] => Array ( [0] => -171.12900859213 [1] => -23.251001225378 ) [9] => Array ( [0] => -152.49300807866 [1] => -32.559001622754 ) [10] => Array ( [0] => -133.92170714209 [1] => -41.834100838885 ) ) 

So far so good. It respects the format from example. But in the DXF file does write only 1 (from array number). If I change the code in

$d->append(new DxfPolyLine(array('points'=>array($g[3]),

with array[3] - it does write the coordinates in DXF file. Is there a way to make php to read all arrays from an array? I've tried with foreach but it doesn't work. PHP gives an error for not closing the ). The source code is here: https://github.com/digitalfotografen/DXFwriter
With $g[3] I have the coordinates from array[3] in DXF file:

VERTEX
8
0
6
CONTINUOUS
10
-211.445
20
-6.474
0

If I put $g simple I have:

VERTEX
8
0
6
CONTINUOUS
10
1.000
20
1.000
30
1.000
40
1.000
50
1.000
60
1.000
70
1.000

I recreated the $g array based on your dump. Does this outputs the desired DXF file?

$g = [[-133.92170714209, -41.834100838885],
      [-135.19600658422, -44.558002415365],
      [-173.40700872797, -25.465001344078],
      [-211.44500829533, -6.4740001788315],
      [-209.93490817601, -3.255100166471 ], 
      [-190.0770099388 , -13.202000524885],
      [-171.92300716209, -22.296000898041],
      [-172.13500940166, -22.749000947663],
      [-171.12900859213, -23.251001225378],
      [-152.49300807866, -32.559001622754],
      [-133.92170714209, -41.834100838885]
     ];
$d->append(new DxfPolyLine(['points' => $g]));

regarding building the array, you could do something like this:

for ($z = 0;  $z < $numar; $z+=2) {
   $g[] = [$coord[$z]*3.527785,$coord[$z+1]*3.527785];
}
