php - adding data into json - php

Question

I am trying to know if the new data can be added to JSON before encoding it?
I am retrieving the data from MySQL database in the following way:
//fetch the data from the database
while ($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
$to_encode[] = $row;
}
which gives me this:
[
{
name: "aaa"
},
{
name: "bbb"
}
]
Then I encode it to JSON with:
$array1 = json_encode($to_encode)
I wanted to know if I can add more data into the array before encoding it to make it like this?
[
{
name: "aaa"
age: '5'
},
{
name: "bbb"
age: '5'
}
]
or should I decode the encoded JSON, add the new values and then encode it back?

Answer 1

Simply you can do like this:
//fetch the data from the database
while ($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
$to_encode[] = $row;
}
for ($i = 0; $i < count($to_encode); $i++) {
$to_encode[$i]['age'] = '14';
}
$array1 = json_encode($to_encode);
print_r($array1);

Try something like this :
$i=0;
while ($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
$to_encode[$i]["name"] = $row;
$to_encode[$i]["age"] = 5;
$i++;
}
$array1 = json_encode($to_encode)

You can push an array to the $row variable, the idea is to build the array before you use json_encode
$to_encode = [];
while ($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
$age = array('age'=>5);
array_push($to_encode,$row);
array_push($to_encode,$age);
}
$array = json_encode($to_encode);
