This looks like a string not an array.

Assuming it is actually an array, you can loop through it along the
lines of something like so:
$vars = '?';
for($i = 0; $i < sizeof($array); $i++) {
$vars .= "array[]=" . urlencode($array[$i]) . '&';
}
Then the receiving page will have an array $_GET['array'] filled with
elements.
If it's an associative array you can do this:
$vars = '?';
foreach($array as $name => $value) {
$vars .= $name . '=' . urlencode($value) . '&';
}
You can also use the serialize and unserialize functions to turn the
array into a string which you would then use urlencode make it url
safe.
