Hi,

Thanks for your contribution !

I have a problem with your pull request. Your parseJSON function returns a null response because of the substr. By removing it, it works.
Is the substr function necessary ?

[MateuszWilk]

I was getting a UTF-8 BOM formatted JSON string from prestashop webservice which was returning null from json_decode. The substring was the only way I found to make it return an associative array. What version of prestashop are You using? (mine was 1.6.1.11)

I'm using Prestashop 1.6.1.11 too.

What are your URL path and query and what does $request['response'] return ?
Here is mine (indented) response :

{  
    "products":[  
        {  
            "id":1,
            "id_manufacturer":"1",
            "id_supplier":"1",
            "id_category_default":"5",
            "new":null,
            "cache_default_attribute":"1",
            "id_default_image":"1",
            "id_default_combination":"1",
            "id_tax_rules_group":"1",
            "position_in_category":"0",
            "manufacturer_name":"Fashion Manufacturer",
            "quantity":"0",
            "type":"simple",
            "id_shop_default":"1",
            "reference":"demo_1",
            "supplier_reference":"",
            ...

Her is my indented $request['response']:

{
   "products":[
      {
         "id":2,
         "id_manufacturer":"1",
         "id_supplier":"1",
         "id_category_default":"2",
         "new":null,
         "cache_default_attribute":"7",
         "id_default_image":"25",
         "id_default_combination":"7",
         "id_tax_rules_group":"1",
         "position_in_category":"1",
         "manufacturer_name":"Fashion Manufacturer",
         "quantity":"0",
         "type":"simple",
         "id_shop_default":"1",
         "reference":"demo_2",
         "supplier_reference":"",
         ...

And as the string looks OK when I do a bin2hex on the string and the $request['response'] there is a 6 char length difference. This are the first values of both 'bin2hex' results:

plain string = "7b2270726..."
$request['response'] = "efbbbf7b2270726..."

As You can see the response has a prepended 6 chars which are efbbbf.

[loicsapone]

That's strange because these 6 hex chars correspond to 3 ASCII chars (ï, » and ¿) that does not appear in your JSON result and I don't have these chars in my $request['response']...
Maybe the problem come from your server. On which machine is running your prestashop and your Symfony2 project (OS, version, *AMP) ?
