Answer 1

Ok so the problem is that "passenger" should be an array of objects so try changing your code to
$passenger1 = new stdClass();
$passenger1->seatNumber = "40";
$passenger1->name = "*****";
$passenger1->age = "20";
$passenger1->gender = "Male";
$passenger2 = new stdClass();
$passenger2->seatNumber = "41";
$passenger2->name = "*****";
$passenger2->age = "21";
$passenger2->gender = "Female";
$post = array(
"operatorCode"=>"9",
"scheduleCode"=>"84W92XC8LOBAF3KZP4",
"travelDate"=>"2015-03-20",
"fromStationCode"=>"84",
"toStationCode"=>"76",
"boardingPointCode"=>"191933",
"droppingPointCode"=>"0000",
"email"=>"*********",
"mobile"=>"*******",
"passenger"=>array( $passenger1, $passenger2 )
);
This will generate the following result
{
"operatorCode":"9",
"scheduleCode":"84W92XC8LOBAF3KZP4",
"travelDate":"2015-03-20",
"fromStationCode":"84",
"toStationCode":"76",
"boardingPointCode":"191933",
"droppingPointCode":"0000",
"email":"*********",
"mobile":"*******",
"passenger":[
{
"seatNumber":"40",
"name":"*****",
"age":"20",
"gender":"Male"
},
{
"seatNumber":"41",
"name":"*****",
"age":"21",
"gender":"Female"
}
]
}
Also I am note sure why you are using
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
Would not
curl_setopt($ch, CURLOPT_POST, true);
be a better option?
