need help with arrays and unserialize

ungovernable

i'm trying to use str_replace to delete an item in a serialized array...

but i'm stuck at unserializing.... it always returns the word "Array" instead of my real serialized datas

here is my code

include("db.php");
$query = "SELECT options FROM quebec_calendarcustomfield WHERE calendarcustomfieldid = '1'";
$res = mysql_query($query) or die(mysql_error());  

while($row = mysql_fetch_array($res)) { 
$a = $row["options"];

$unseri = unserialize($a);
$hmm = str_replace("$title", "", "$unseri");
echo $hmm;

From the [man]str_replace[/man] page for the 3rd argument:

If subject is an array, then the search and replace is performed with every entry of subject , and the return value is an array as well.

So if you just want to output the result for debugging purposes, use [man]print_r/man or [man]var_dump/man instead of echo. If you want to create actual output to the client, you'll probably want to do a foreach() on the $hmm array, then echo each element.

I guess thats what i want to do then

could you give me an example with my code ... i'm confused ><

Instead of this...

echo $hmm;

...do one of these...

echo "<pre>".print_r($hmm, 1)."</pre>\n";

// ...or...

foreach($hmm as $value)
{
   echo $value."<br />\n";
}

In other words, since $hmm is an array, you cannot just "echo" it and get any meaningful output.
