[PHP] A few errors...

[Topps]

Hey guys, I have a few little errors in my grid.save.php file, these are the errors...

Warning: preg_match_all() [function.preg-match-all]: Unknown modifier 'a' in localhost\homes\grid.save.php on line 8

Warning: Invalid argument supplied for foreach() in localhost\homes\grid.save.php on line 14

...obviously its a problem with 2 certain codes, preg_match_all() and foreach() I don't know what is wrong though.

Here is my file:

 <?php
require_once "grid.config.php";
// Call the grid.config.php file.

$data = $_POST['object_data'];
// Assign the object_data post to the $data variable

preg_match_all("/[array](.*)[/array]/imU", $data, $parsed, PREG_PATTERN_ORDER);
// Match all instances of the [array], [/array] tags and their contents.

$parsed_data = array();
// Create an empty array

foreach ($parsed[1] as $data) // Loop through the parsed array
{
    $parsed_data[] = $data;
    // Add each objects contents to the new array we just created
    $tags = array(
"id",
"title",
"src",
"width",
"height",
"top",
"left",
"zindex"
);
// Array of all allowed object tags

$all_objects = array();
// New array

foreach ($parsed_data as $data) // Run through each object array
{
    $object = array();
    // Create temp new array

    foreach ($tags as $tag) // Run through valid tags
    {
        preg_match_all("/[$tag](.*)[/$tag]/imU", $data, $parse, PREG_PATTERN_ORDER);
        // Get contents of tag from current object
        
        $object[] = $parse[1][0]; // Add contents to the object array
    }
    
    $all_objects[] = $object; // Add the object array to a all_objects array
}
$assoc = array(); // Create empty array

foreach ($all_objects as $object => $attribute) // Loop through the all_objects array
{
    $info = array(); // Create new info array
        
    $info['obj_id'] = $attribute[0];
    $info['obj_title'] = $attribute[1];
    $info['obj_src'] = $attribute[2];
    $info['obj_width'] = $attribute[3];
    $info['obj_height'] = $attribute[4];
    $info['obj_top'] = $attribute[5];
    $info['obj_left'] = $attribute[6];
    $info['obj_zindex'] = $attribute[7];
    // Add all the attributes to the info array    
    
    $assoc[] = $info; // Add the current info array to the newly created assoc array.
}
foreach ($assoc as $object) // Loop through the assoc array.
{
    if (substr($object['obj_title'], 0, 8) != "deleted_") // If the object was not deleted in the script...
    {
        $find_object = mysql_query("SELECT * FROM `object` WHERE `obj_id` = '" . $object['obj_id'] . "'");
        // Search for the object in the database
