Array
(
    [0] => Array
        (
            [name] => Lorem
            [number] => 11
        )

    [1] => Array

            [name] => ipsum
            [number] => 22
        )

Hi guys,
I have this result:
Array ( [0] => Array ( [cod_piesa] => gl [ lungime] => 5000 [ latime] => 3000 [ inaltime] => 150 ) [1] => Array ( [cod_piesa] => fd [ lungime] => 3000 [ latime] => 2000 [ inaltime] => 100 ) )

What I would like to do is to insert the above results in a table like this:

$line = 0
$part = GL
$cota = lungime
$value = 5000

then to insert another row in mysql
$line = 0
$part = GL
$cota = latime
$value = 3000

and so on with each line basically I have a component code with different dimensions, instead of inserting in a huge table in mysql I want to add it as a list with while or something.

Thank you very much!

This is what I have in the csv

cod_piesa, lungime, latime, inaltime
gl, 5000, 3000, 150
fd, 3000, 2000, 100
