Struggling to convert to json string - php

Question

I've got a textbox that the user can enter details into it in a csv format. So they would enter something like
user 1,user1#email.com
user 2,user2#email.com
user 3,user3#email.com
The out put of that when I dd(request('users')) is this
user 1, user1#email.com\n
user 2, user2#email.com\n
user 3, user3#email.com
What I would like is to save it in a json format so that it can end up looking like this
[
{
"name": "user 1",
"email": "user1#email.com"
},
{
"name": "user 2",
"email": "user2#email.com"
},
{
"name": "user 3",
"email": "user3#email.com"
}
]
I'm struggling to get it to be like how I would like it. I've tried json_encode(request('users')) but I ended up with
""user 1, user1#email.com\nuser 2, user2#email.com\nuser 3, user3#email.com""
I also tried this
$replace = preg_replace('/\n+/', "\n", trim(request('users')));
$split = explode("\n",$replace);
$json = json_encode($split);
but I got this
"["user 1, user1#email.com","user 2, user2#email.com", "user 3, user3#email.com"]"

Answer 1

The keys name and email you want in your result are not going to appear out of thin air, you need to create them.
Split the data into individual lines, loop over those lines.
Split each line into its two parts.
Create the necessary data structure, introduce the keys you want the data to be stored under at this point.
Encode the whole thing as JSON.
$data = 'user 1,user1#email.com
user 2,user2#email.com
user 3,user3#email.com';
$lines = explode("\n", $data);
$result = [];
foreach($lines as $line) {
$parts = explode(',', $line);
$result[] = ['name' => $parts[0], 'email' => $parts[1]];
}
echo json_encode($result);

You can simply use array_map to map each line to a key-value pair created by using array_combine:
$array = array_map(function($line) {
return array_combine(['name', 'email'], str_getcsv($line));
}, explode("\n", $request('users')));
$json = json_encode($array);
var_dump($json);
The result would be:
string(133) "[{"name":"user 1","email":"user1#email.com"},{"name":"user 2","email":"user2#email.com"},{"name":"user 3","email":"user3#email.com"}]"

Try this
$xx = "user 1, user1#email.com\nuser 2, user2#email.com\nuser 3, user3#email.com";
$xxx = explode("\n",$xx);
$res = [];
foreach($xxx as $y)
{
$new = explode(',',$y);
$res[] = [
'name' => $new[0],
'email' => $new[1]
];
}
echo json_encode($res,true);
Output will be
[
{
"name":"user 1","email":" user1#email.com"
},
{
"name":"user 2","email":" user2#email.com"
},
{
"name":"user 3","email":" user3#email.com"
}
]

Try this
$data = explode("\n", trim(request('users')));
$result = collect($data)->map(function ($row) {
$columns = explode(',', $row);
return [
'name' => $columns[0] ?? null,
'email' => $columns[1] ?? null
];
});
