Why I can't use separators (.) in variables inside a class?
class Object(){
public $var = "Hello"."World";
# Or
public $test = "Hello";
public $var2 = $this->test."World";
}
This code gives me this error:
Parse error: syntax error, unexpected '.', expecting ',' or ';' in test.php on line 2
And how should I do it?
Because you cannot declare class properties with variable expressions. That means you cannot use any arithmetic operators + - * / or the concatenation operator ., and you can't call functions. Out of your three lines, only $test should work; the other two will give you errors.
If you need to build your strings dynamically, do it in the constructor.
class Object {
public $test = "Hello";
public $var2;
public function __construct() {
$this->var2 = $this->test . "World";
}
}
By the way, . is not a "string separator". It's the concatenation operator. You use it to join strings, not separate them.
