php - Writing Json Array To Databases With Laravel -

i have array follows contained in $config:

array (     [1] => array         (             [outlet] => facebook             [thumbnail] => /images/catalog/modules/videoplayer/original.jpg             [url] => http://www.google.com             [copy] => test             [vidurl] => http://www.youtube.com             [poster] => none         )      [2] => array         (             [outlet] => facebook             [thumbnail] => /images/catalog/modules/videoplayer/limon2.jpg             [url] => http://www.yahoo.com             [copy] => here copy             [vidurl] => http://www.vimeo             [poster] => no poster         )  ) 

i'm converting json follows:

$module->configuration = json_encode($config,json_pretty_print); 

everything saves db fine, producing object upon retrieval:

app\module object (     [table:protected] => modules     [timestamps] =>      [connection:protected] =>      [primarykey:protected] => id     [perpage:protected] => 15     [incrementing] => 1     [attributes:protected] => array         (             [id] => 3             [title] => wddwdw             [type] => socialfeed             [configuration] => {     "1": {         "outlet": "facebook",         "thumbnail": "\/images\/catalog\/admin\/no_image.png",         "url": "wdwd",         "copy": "wd",         "vidurl": "wdw",         "poster": "wd"     },     "2": {         "outlet": "facebook",          )      [original:protected] => array         (             [id] => 3             [title] => wddwdw             [type] => socialfeed             [configuration] => {     "1": {         "outlet": "facebook",         "thumbnail": "\/images\/catalog\/admin\/no_image.png",         "url": "wdwd",         "copy": "wd",         "vidurl": "wdw",         "poster": "wd"     },     "2": {         "outlet": "facebook",          )      [relations:protected] => array         (         )      [hidden:protected] => array         (         )      [visible:protected] => array         (         )      [appends:protected] => array         (         )      [fillable:protected] => array         (         )      [guarded:protected] => array         (             [0] => *         )      [dates:protected] => array         (         )      [dateformat:protected] =>      [casts:protected] => array         (         )      [touches:protected] => array         (         )      [observables:protected] => array         (         )      [with:protected] => array         (         )      [morphclass:protected] =>      [exists] => 1 ) 

as can see json broken. when retrieve $model->configuration broken:

{     "1": {         "outlet": "facebook",         "thumbnail": "\/images\/catalog\/admin\/no_image.png",         "url": "wdwd",         "copy": "wd",         "vidurl": "wdw",         "poster": "wd"     },     "2": {         "outlet": "facebook", 

is there else need before writing json db make sure retrievable?

like said @scuzzy in comments, think have length problem here. either used varchar (255) store json in db, that's why it's cut, because string long or maybe it's var_dump or print didn't show , object fine.

i think it's first case, , suggest store serialized array instead of json in db.
