unserialize errors PHP 4 -> 5

[Sarah]

Hi All

I have a slight issue I am porting a website from old hosting to new hosting - using exact same code and database just new servers I am seemingly not able to get the images displayed as the old site does - this is the lines of code in question and having never really used serialize before I was not sure if anyone knew if there was any issues with old PHP and new PHP with it?

    $image_list = unserialize( $product['image'] );
echo $image_list; 

Thanks

What is the content of $product['image']?

What was the error?, $product['image'] is a serialized data?

[Sarah]

I just get nothing - no error no nothing if I do this:

echo '<p>' . $kernel->html_chars( $product['image'] ) . '</p>'; 

then I see this is the serialized data

a:59:{i:0;s:7:"9ra.jpg";i:1;s:7:"6ra.jpg";i:2;s:8:"10ra.jpg";i:3;s:8:"9100.JPG";i:4;s:15:"apache unit.jpg";i:5;s:17:"apache unit2..jpg";
....<snip>....
;i:58;s:12:"IMG_0051.JPG";}

Seems your serialized data is corrupt.
>s:8:"9100.JPG "
This is 9 chars including the space at the end but declared as 8

If that's no copy'n'paste error you should really check your data.
Oh, and regarding your "no error, no data" - unserialize() returns boolean FALSE upon data corruption and emits an E_NOTICE, so check your error_reporting-level.

wow so that is what they mean! damn this data was sent to me as I don't have mysql access on old hosting (hence they move!) damn thank you I will chase them now as I have seen other corrupt data and didn't think that would be the case here!

Hopefully it was corrupt data that they sent you, because that will be easiest to remedy.

I have seen this issue before though.

I would try pasting the serialized data in http://tools.perceptus.ca/text-wiz.php?ops=6 and see if it is able to unserialize it properly.

If not, then the data is probably corrupted.

Thanks guys those links are very very helpful I am suggesting that I upgrade as the omments are quite right in that you should not be using PHP4 code that doesn't work in PHP5 as that would just cause so many issues within the future! Nightmare now for hopefully smooth(er) sailing in the future
