Question

The output is the result of the codes:

    $bytes= fread($handle,"32");
    print_r(unpack("La/fb/fc/fd/fe/ff/fg/fh",$bytes)); 


Array ( [a] => 20150416 [b] => 1.0499999523163 [c] => 1.25 [d] => 1.0299999713898 
[e] => 1.1900000572205 [f] => 509427008 [g] => 566125248 [h] => 509427008 ) 

How to write the proper format in unpack if the wanted output is as following ?

Array ( [1] => 20150416 [2] => 1.0499999523163 [3] => 1.25 [4] => 1.0299999713898 
[5] => 1.1900000572205 [6] => 509427008 [7] => 566125248 [8] => 509427008 ) 

Answer 1

Use array_values, it keeps the order (first index is 0):

$bytes = fread($handle,"32");
$un = unpack("La/fb/fc/fd/fe/ff/fg/fh",$bytes);
print_r(array_values($un));

Edit (if you want first index 1):

$bytes = fread($handle,"32");
$un = unpack("La/fb/fc/fd/fe/ff/fg/fh",$bytes);
array_unshift($un, NULL);
$array = array_values($un);
unset($array[0]);
print_r($array);
