How to pack complex expresions?

For example:

In python:
pack("<4BI2H", 3, 118, 02, 26, 0, 161, 58)
�v���;

Trying to do the same in php:
pack("<4BI2H", 3, 118, 02, 26, 0, 161, 58)
""
Using an array to force the values recognition in php:
pack("<4BI2H", array(3, 118, 02, 26, 0, 161, 58))
��

So, they are not matching...

Just for point you in the right direction. If i split all values then is working:
$_p = pack("<B", array(3));
$_p1 = pack("<B", array(118));
$_p2 = pack("<B", array(02));
$_p3 = pack("<B", array(26));
$_p4 = pack("<I", array(0));
$_p5 = pack("<H", array(161));
$_p6 = pack("<H", array(58));

$_p . $_p1 . $_p2 . $_p3 . $_p4 . $_p5 . $_p6
�v���;

This is the same of python.

Probably:
$tmp = array_slice($a, $p, $s);
need to be:
$tmp = array_slice($a, $p, $n);
or
$tmp = array_slice($a, $p, $s*$n);

Because you are converting series that can have more than one value. So if you want to convert just B, you need one value from b, but if you want 2B you need to have 2 values of the array.

Edit:
The length of B is $s=1, this is why i don't know if you need $s*$n or just $n.
