[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 (http://localhost/Loading.FM/homes/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("/(.*)/imU", $data, $parsed, PREG_PATTERN_ORDER);
// Match all instances of the , 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"
);

$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_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.
{

Thanks for any help in advance everyone! :)
