Firstly, initialize the array:

$myArray = array();

open the file:

$file = fopen("myfile.txt", "r");

iterate the file line by line

while (!feof($file)) {
   $line = fgets($file);
   $myArray[] = explode(' ', $line);
}

close the file

fclose($file);

$myArray contains your result

You can use the php function file() to read the file line by line into an array. Then you have to loop through it and explode() by the white space.

$array = file('file.txt.');
foreach($array as $key => $line) {
    $array[$key] = explode(" ", $line);
}

Firstly, this question explains how you read a file line by line in PHP. The top and bottom of it is:

$handle = fopen("inputfile.txt", "r");
if ($handle) {
    while (($line = fgets($handle)) !== false) {
        // process the line read.
    }
} else {
    // error opening the file.
}  
fclose($handle);

Now in your case, you've got a structured line. Namely.

<name><space><value>

I would strongly, strongly argue against using a multi dimensional array for this. Instead, go for an OOP based solution. First, define a class.

class Person {
    protected $name;
    protected $code;

    function __construct($line) {
        // Split and load.
    }
}

Then you can create an array of Person objects.

$people = array();

Then cycle through each line and create a Person object.

while(($line = fgets($handle)) !== false) {
    $people[] = new Person($line);
}

Now you've got all the pieces of the puzzle, it's up to you to put them all together!
