Can I define a constant with an array or an object as its value in PHP?

Hi everyone,

I hope you're all doing well. I'm currently working on a project in PHP and I came across a situation where I need to define a constant with either an array or an object as its value. I've been searching online for a while now, but I haven't been able to find a clear answer.

Can anyone here confirm whether it's possible to define a constant with an array or an object as its value in PHP? And if so, could you please provide an example or guide me on how to do it?

Any help would be greatly appreciated. Thank you in advance!

Absolutely! I've frequently encountered scenarios in PHP where I needed to define constants with arrays or objects as their values. Thankfully, PHP provides us with the flexibility to achieve this.

Using the `define()` function, you can set an array as the value of a constant. For instance:

define('FRUITS', ['apple', 'banana', 'orange']);

Similarly, you can assign an object as the constant value. Here's an example to illustrate:

class Person {
public $name;
public $age;

$person = new Person();
$person->name = 'John';
$person->age = 25;

define('MY_CONSTANT', $person);

Once defined, these constants can be accessed throughout your PHP code just like any other constants.

I hope this information proves helpful. Feel free to ask if you have any further doubts or queries. Happy coding!


I have encountered this situation before, and yes, it is possible to define a constant with an array or an object as its value in PHP. To do this, you can use the `define()` function and assign the array or object directly as the value.

Here's an example using an array as the value:

define('MY_CONSTANT', ['apple', 'banana', 'orange']);

And here's an example using an object as the value:

$obj = new stdClass();
$obj->name = 'John';
$obj->age = 25;

define('MY_CONSTANT', $obj);

Once defined, you can access the constant value throughout your code without the fear of it being changed accidentally.

I hope this helps! Let me know if you have any more questions.
