php class in an array - php

Question

I have a php file where I have an array with some data in classes like this: (in javascript)
array = [
{engine: "V6",
capacity: 2.5,
hp: 300
}]
I tried to put this into a php file but it gave me 500 error
$array = [{engine => "V6",
capacity=> 2.5,
hp=> 300}];
I think I may be doing something wrong over here, could someone confirm?

Answer 1

You can't just translate JavaScript code into PHP without understanding the syntax of both languages.
In JavaScript, this creates an array containing an object:
var array = [
{
engine: "V6",
capacity: 2.5,
hp: 300
}
]
In PHP, the common equivalent would be an array containing another (associative) array, which would be written like this:
$array = [
[
'engine' => "V6",
'capacity' => 2.5,
'hp' => 300
]
];
As an aside, since it's been mentioned elsewhere on this page, you could also write the same thing in JSON like this:
[
{
"engine": "V6",
"capacity": 2.5,
"hp": 300
}
]
If you called JSON.stringify(array) in JavaScript, or json_encode($array) in PHP, that's how the JSON string you'd get would look.
The JSON looks very similar to the JavaScript, because JSON's syntax was based on JavaScript's. In fact, the above would be valid JavaScript code, and you can use (arguably, abuse) json_encode as a way to generate JavaScript code using PHP.
Note that none of these contains any kind of "class" - a class is a way of defining a type of object, from which you want to make several instances.

Answer 2

You are mixing PHP with JSOL or JSON. PHP doesn't read JSOL nor JSON natively.
<?php
$array = [
[
'engine' => 'V6',
'capacity' => 2.5,
'hp' => 300
],
];
echo json_encode($array);
