If you want to create a multidimensional array, you do it like this: 
@array = ( [ "foo", "bar"],
           [ "abc", "def"] );

You can access elements with 2 array subscripts - $array[0][0] is "foo", $array[0][1] is "bar", $array[1][0] is "abc", etc.

Supposing that your file of projects had each project on 1 line, you could do this: 

while ( <FILE> ) {
    push @array, [ split ];
}

Then to print it back out, 

for $i (0..$#array) {
    for $j (0..$#{$array[$i]}) {
        print "Element $j of project $i is $array[$i][$j]\n";
    }
}
