My document where data is to be inserted is:
Data has to be appended to array with key as Solutions
Suppose $data has some numerical value
array(8) {
["_id"]=>
object(MongoId)#9 (1) {
["$id"]=>
string(24) "56d32613097ed36c10000049"
}
["Username"]=>
string(4) "xxx"
["Solutions"]=>
array(0) {
}
}
Suppose $j= "The entire above array"
How to push the value of $data in the array having key as "Solutions"?
