count(): Parameter must be an array or an object that implements Countable at LINE 428 error in PHP

Question

Am trying to save some data to an API which but I keep getting this error count(): Parameter must be an array or an object that implements Countable at LINE 428,,, the API am posting data to accepts an array of objects but in my data children variable is throwing the above error..

Please assist?

$children = '[{"child_name" => "Mmansa" , "child_dob" => "jdhjdhjd" }]'; 

$data = [
      'quote_id' => $quote,
      'country_residence' => $resd,
      'physical_address' => $physical,
      'children' => $children,
];

Post via Curl

$res = $this->global_Curl($data, 'api/travel/save-policy-meta');

Curl function

 public function global_Curl($data, $url)
    {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, (env('API_ENDPOINT_NGINX_IP') . '/' . $url));
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_FRESH_CONNECT, TRUE); 
        $response = json_decode(curl_exec($ch));
        curl_close($ch);
        return $response;
    }

Data required by the API

{
"quote_id":136,
"country_residence":"Japan",
"physical_address":"Tokyo",
"children":[
    {"child_name":"abc","child_dob":"23-05-2015"}
  ]
}

You doesnt' need to declare `$children` as string. Works with array and use `json_encode()` to convert array to json. — Oleg Nurutdinov, Nov 20 '18 at 07:26
@BartFriederichs Am not using any count call anywhere am just posting the data to the API — Patweb, Nov 20 '18 at 07:26
'[{"child_name" => "Mmansa" , "child_dob" => "jdhjdhjd" }]'; probably isn't readable as array for your API , just a string — WKoppel, Nov 20 '18 at 07:28
@OlegNurutdinov I converted the array to Json but it still throws the same error — Patweb, Nov 20 '18 at 07:29

Your API need JSON request, Which you are sending as a array in CURLOPT_POSTFIELDS and also having one field as invalid JSON string

This string is not a valid JSON

'[{"child_name" => "Mmansa" , "child_dob" => "jdhjdhjd" }]'

It supposed to be like this

'[{"child_name" : "Mmansa" , "child_dob" : "jdhjdhjd" }]'

Here no need to write a JSON string, Instead of this you can use json_encode() method to convert a array to JSON string

Change this

$children[] = ["child_name" => "Mmansa" , "child_dob" => "jdhjdhjd"]; 

$data = [
  'quote_id' => $quote,
  'country_residence' => $resd,
  'physical_address' => $physical,
  'children' => $children,
];

And try this code

public function global_Curl($data, $url)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, (env('API_ENDPOINT_NGINX_IP') . '/' . $url));
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FRESH_CONNECT, TRUE); 
    $response = json_decode(curl_exec($ch));
    curl_close($ch);
    return $response;
}

@sanu Thanks alot,, it works fine... What if I have another children array,, can I do this: `$children[] = ["child_name" => "Mmansa" , "child_dob" => "jdhjdhjd"] ["child_name" => "Mmansa" , "child_dob" => "jdhjdhjd"]; ` — Patweb, Nov 20 '18 at 07:55
@Patweb If you have another children array you have to add in separate line for example `$children[] = ["child_name" => "child1" , "child_dob" => "dob1"];` `$children[] = ["child_name" => "child2" , "child_dob" => "dob2"];` Wish you a happy Coding — sanu, Nov 20 '18 at 07:56
