Seeing other languages like Java or C++, String is an Object.
But in PHP is it the same thing?

PHP supports OOP, but is not fundamentally oop-based. strings are not objects in PHP.Marc B– Marc B2013-03-28 16:11:59 +00:00Commented Mar 28, 2013 at 16:11

You can actually have a string object in PHP with the SPL Types: php.net/manual/en/class.splstring.php ... but this is very new and very buggyMark Baker– Mark Baker2013-03-28 16:23:47 +00:00Commented Mar 28, 2013 at 16:23

It's not natively an object but you could create your own string class if you wished. Just a few days ago I was thinking about this.EM-Creations– EM-Creations2013-03-28 16:30:53 +00:00Commented Mar 28, 2013 at 16:30

Is it the literal "String"? Or just a string?Peter Mortensen– Peter Mortensen2023-11-14 15:07:38 +00:00Commented Nov 14, 2023 at 15:07

A String is not an object in PHP by default and casting is not required but it can be introduced if you want using scalar_objects
class StringHandler {
public function length() {
return strlen($this);
}
}
register_primitive_type_handler('string', 'StringHandler');
So you can easily have
$str->length();

A string is not an Object in PHP. You don't have to cast the types of variables in PHP. See
http://www.php.net/manual/language.types.string.php
and http://php.net/manual/language.types.type-juggling.php

Ok so a string is a string I guess.
powtac
$name = "John"; makes a String. PHP is much simpler than C(++) in this case. It tries to figure out what type your suggest.Shadowbob
So I need to write it string and not String. Sorry I like the conventions :-)
powtac
If you want you can write
$name = (string)"John"; or $number = (int)"99";String and object are two different things. But if you wanted to run your own checks:
if (is_object($var))
{
echo "Var is an object";
}
elseif (is_string($var))
{
echo "var is a String";
}
else
{
echo "var is neither an object or string";
}

I already did this test, but I wasn't sure if they just replaced the object kind by a string kind which it could had been itself an Object... That's the purpose of my question :-)

@user1682624 As a majority of the answers have stated, a string is not an object.. the same concept with an object being a string, the other answers provided are your solution

This isn't really an accurate answer.
String is not an object in PHP; it's a primitive type. The information is on Types.
A lowercase string is correct for the few uses you might have.

What do you mean by the last sentence?

OK, the OP has left the building: "Last seen more than 2 years ago"
Everyting can be achieved via the built-in functions of PHP, so you can do all that you can with String objects.

A string is not an object; it is a basic type.
