I am reading form a a file that print out of the following.
{
"draw":0,
"recordsTotal":3995,
"recordsFiltered":1,
"data":[
{
"customer_id":"1",
"channel":"2",
"date":"2017-03\/21 ",
"earnings":"2500"
},
{
"customer_id":"2",
"channel":"2",
"date":"2017-03\/21 ",
"earnings":"1500"
}
]
}
is it possible in a separate php file to read this and to calcualte the total earnings?
i.e 2500 + 1500 = 4000
