coding problem--need help

[oracle259 0]

I have the following code which should generate something like this

c8aad58bd948b0245a78c5b03ace6a333b94827eef5c865372f65e81e96346f4051314e7ce7854f5

instead it does this:

$token[$h].$token[$h].$token[$h].$token[$h].$token[$h].$token[$h].$token[$h].$token[$h].$token[$h].$hash[$h]

I know that the problem is with how i constructed $track and passed it to $sessid. But how do i fix it

[code]
$token=' ';
for ($f=1;$f<=100;$f++) {
$seedID = substr('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz123456789~!@#$%^&*+?.', rand(1,73), 1);
$trackingID .= trim($seedID);
}
$token = sha1(uniqid(trim($trackingID)));

for ($g=1;$g<=10;$g++) {
srand((double)microtime()*1000000);
$seq .= rand(1,2);
}
    $toke = "$"."token["."$"."h].";
      $hashen = "$"."hash["."$"."h].";
                               
    $track = eregi_replace("1", "$toke", "$seq");
      $track = eregi_replace("2", "$hashen", "$track");
      $string = strlen($track) - 1;
        $track = substr($track, 0, $string);

$sessid = '';
for($h=0;$h<strlen($token);$h++) {
          $sessid = $track;
         
}



 
echo $sessid;
