Insertion into serialized array in PHP

Question

This is my first time here, and I am pulling my hair out because of this, so I thought it would be a good first question for me.

I save the array data in a mysql database, and then later use unserialize to edit it. The problem is that it processes every other index in the array when I edit only one index. Here is a sample code:

foreach($post as $key => $value)  {
     if (isset($row)) {
        if ($i > 2) { $tempArray = unserialize($row[$i]); }
     }

     $tempArray[$time] = $value;

     if ($key == 'pid' || $key == 'uid') { $data[$key] = $value; }
     else { $data[$key] = serialize($tempArray); }
     $i += 1;
     unset($tempArray);
  }

Thanks for any insight you can give.

for storing data in an array in mysql and for restoring and saving it in the same table, here is how to do it.

. , , .

mysql .

:

$data = array(
   "uid" => "some value",
   "pid" => "some value"
);

$store_in_database = serialize($data);
/* ...do the mysql insert query to store the new data in the field (serializedfield)... */

, .

/*... ( ) */

foreach($db_result as $db_row){

$temp_array = $db_row['serializedfield'];
$temp_array['uid'] = "a new value";
$temp_array['pid'] = "another new value";

/* ... i wanted to add another array value */
$temp_array['akey'] = "some value";
$store_database = serialize($temp_array);
/* ... do the mysql update query to replace this new data with the old one. */
unset($temp_array);

}
