Over the past week, some readers have reported that they have encountered an offset weakening error.

unsialize () [function.unserialize]: only error occured with offset
, which helps invalid serialization data
due to incorrect length
What you can do is recalculate the length of the back array element
$ data serialized = 'a: 10: s: 16: "submit_editorial"; b: 0; s: 15: "submit_orig_url"; s: 13: "www.bbc.co.uk"; s: 12: "submit_title"; s: 14: "No reputation found"; s: 14: "submit_content"; s: 12: "dnfsdkfjdfdf"; s: 15: "submit_category"; i: 2; s: 11: "Submit_tags"; s: 3: "BBC"; s: 9: "submit_id"; b: 0; s: 16: "submit_subscribe"; i: 0; s: 15: "submit_comments"; s: 4: "open"; s: 5: "Image"; s: 19: "C: fakepath100.jpg"; ';
var_dump (unsialize ($ data));
Note: unsialize () [function.unserialize]: on error reduce to 337 by 338 bytes
$ data = preg_replace ('! s: ( d +): "(. *?)";! e', "'s:'. strlen ('$ 2'). $ data) ;Var_dump (unialize (data $));
table ': "$ 2 ";' ", 'submit_editorial' => boolean false 'submit_orig_url' => String 'www.bbc.co.uk' (length = 13) 'submit_title' => 'String id not found' (length = 14) 'submit_content' => Number 'dnfsdkfjdfdf' (length = 12) 'submit_category' => integer 2 'submit_tags' => Guitar string 'bbc' (length = 3) 'submit_id' => boolean false 'submit_subscribe' => integer 0 'submit_comments' => string 'open' (length = 4) 'image' => string 'C: fakepath100.jpg '(length = 17)
Instead of doing such a quick preparation … I’ll update my question with

How to continue serializing data
-
How to register a device ..
The error was due to the use of double quotes "
is actually single quotes '
, so C: fakepath 100.png
is converted in C: fakepath100.
Your JPG should be $ h-> vars ['submit_data']
by (Note the individual '
)
$ h-> vars ['submitted_data'] ['image'] = "C: fakepath 100.png";
$ h-> vars ['presented_data'] ['image'] means 'C: fakepath 100.png';
You can also add this type of simple filter before using Satitize (& value $,
function $ key) $ value = add eyelashes ($ value);array_walk ($ h-> vars ['presented_data'], "Satitize");
$ h-> vars ['submit_data'] is array_map ("utf8_encode", $ h-> vars ['submit_data']);
