PHP Database serialized array issue

Got an issue when inserting a blank serialized array into the database. I'm using wordpress (just for full disclosure, shouldn't make a difference) and using the add_post_meta() function to input some additional information. Here's a snippet:

add_post_meta($post_id, 'information', serialize(array()));

The serialized array is intentionally blank for the moment. Anyway here's the expected/actuals:

// Expected value 
a:0:{}

// Actual value
s:6:"a:0:{}";

Any help?

I have faced the same issue but I could used add_post_meta($post_id, 'information', array()); instead of add_post_meta($post_id, 'information', serialize(array())); try it you can resolve your issue..

Add post meta auto-serializes arrays. And also get post meta, pass TRUE at the last argument: like get_post_meta($post_id, 'information', TRUE);
