      "\/something\?t[p]\/"
    ],

not sure what the problem is, can you var_dump the $item['pattern']. — Joako-stackoverflow

I think you might be confusing data types here, between json and array, please rephrase the explanation of this issue, if you please — Joako-stackoverflow

Ok, the thing is one of the elements is an array itself, since http://php.net/manual/es/function.implode.php function expects each of the elements of the array to be a string (or be able to convert into one).

When one of the the elements of the array is an array, it fails. And that's when you have an 'Array to String' conversion error.

Basically you can't implode an array of arrays like that.

In the next code you may see the issue on the 3rd and 4th line

  $array = [];
  $array[0] = "/something/";
  $array[1][1] = "/something/";
  $array[1][2] = "/something2/";

  $aux = implode("@s@",$array);

  var_dump ($aux);

And here is working:

  $array = [];
  $array[0] = "/something/";
  $array[1] = "/something/";

  $aux = implode("@s@",$array);

  var_dump ($aux);

Edit for a comment and some crazy english:

The problem is not the way you are importing it, the thing you are looking for is "implode multidimensional arrays".You can't print an array of arrays as an string like that. You may look here

Implode and Explode Multi dimensional arrays

Solved it. The Problem was in Json File the severity field was set to 0 . while the application only supports value Ranging from 1-9.That was causing the problems.

based on the error shown, that does not seems to be the case. But glad it worked
