I Want To Remove Extra Slash , Unicodes , etc From This Json And Convert To Normal Json i am using str_replace For That But Also Its Fully Not Working ..

Solution

You should find the cause of the slashes in your JSON, if you don't want them there. Removing them afterwards sounds like a patch for an mistake made earlier, and makes your code more complicated than needed.

To decode this you can use:

$object = json_decode($json);
$object->response = json_decode($object->response);

Assuming the JSON is in a string. Which results in:

(object) array(
   'response' => 
  (object) array(
     'reqEntityData' => 
    (object) array(
       'txnid' => 'YSCPAN99458555',
       'reqTs' => '2023-08-19T16:54:34.118Z',
       'entityId' => 'SoftmintUAT',
       'dscProvider' => 'e-Mudhra Sub CA Class 2 for Document Signer 2014',
       'dscSerialNumber' => '01589720',
       'dscExpiryDate' => '03/03/2024 16:05:36 PM',
       'returnUrl' => 'https://uat.softmintdigital.com/panRes',
       'formData' => 'eyJhcHBs................Tm8iOiIifX0=',
       'authKey' => '',
    ),
     'signature' => 'BJZI+6SCmdVjM................CggsU5/prVZod5CBA==',
  ),
   'status' => '1',
)
