How to remove quotations from JSON file while writing from PHP?

I currently have the following code which has an array, and outputs it into a JSON file called 'example.json'.

Below is the code that outputs to it:

PHP

$x = array(1, 2, 3); //Defining two basic arrays
$y = array(2, 4, 6);
$name = array("Joe", "John", "Johnny");
echo count($x);
$objOne = '["type": "FeatureCollection", "features": [';
file_put_contents("jsonfun.json", json_encode($objOne));
for($i = 0; $i < count($x); $i++)
{
    $objTwo = '{ "type": "Feature", "geometry": {"type": "Point", "coordinates": [' . $x[$i] . ', ' . $y[$i] . ']}, "properties": {"name": ' . $name[$i] . '} }]';
    file_put_contents("jsonfun.json", json_encode($objTwo), FILE_APPEND);
}
$objThree = '};';
file_put_contents("jsonfun.json", json_encode($objThree), FILE_APPEND);

Output:
"[\"type\": \"FeatureCollection\", \"features\": [""{ \"type\": \"Feature\", \"geometry\": {\"type\": \"Point\", \"coordinates\": [1, 2]}, \"properties\": {\"name\": Joe} }]""{ \"type\": \"Feature\", \"geometry\": {\"type\": \"Point\", \"coordinates\": [2, 4]}, \"properties\": {\"name\": John} }]""{ \"type\": \"Feature\", \"geometry\": {\"type\": \"Point\", \"coordinates\": [3, 6]}, \"properties\": {\"name\": Johnny} }]""};"

As you may have seen there are a lot of slashes which I don't know where they came from... and likewise there are also several quotations where they shouldn't be;

eg.

"[type...

Is there any chance I could remove those, or am I doing it wrong?

What I have tried:

I have researched into it but wasn't able to find anything...

You need to understand what json_encode() does. See http://php.net/manual/en/function.json-encode.php for starters.

Your code is doing exactly what it is asked for.
Use the debugger to see your code execute.
Advice: store the results of json_encode in temporary variable and inspect the variables with debugger.

You should learn to use the debugger as soon as possible. Rather than guessing what your code is doing, It is time to see your code executing and ensuring that it does what you expect.

The debugger allow you to follow the execution line by line, inspect variables and you will see that there is a point where it stop doing what you expect.
Debugger - Wikipedia, the free encyclopedia[^]
Mastering Debugging in Visual Studio 2010 - A Beginner's Guide[^]

The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't find bugs, it just help you to. When the code don't do what is expected, you are close to a bug.
