For example, let's say I have the file "other.php" that contains this code
class Building
{
public $name;
function __construct($name)
{
$this->$name = $name;
}
}
$bd = new Building("Name");
echo $bd->$name;
This returns errors like this:
Notice: Undefined variable: name in (...)
Fatal error: Cannot access empty property in (...)
And I wish for an output like
Name
How do I access PHP object properties in such a fashion? Thank you.
Get rid of the second $. You access it with $bd->name;. Same goes for inside the class. Put $this->name instead of $this->$name in there.
Generally, just don't put a $ after the -> operator.
Look at the PHP Documentation for reference.
$this->$name, while it should actually be $this->name.<?php include("buildings.php"); ?> and then later on in my index.php write <?php echo $buildings_HSB->name; ?> it gives errors. Notice: Undefined variable: buildings_HSB in (...) and Notice: Trying to get property of non-object in (...)<?php include("buildings.php"); ?> and then <?php echo $buildings_HSB->name; ?> and am receiving the errors listed above.Avoid the $ sign infront of name.
It should be like echo $bd->name;..
First fix your class code:
function __construct($name)
{
$this->$name = $name;
}
Should be this:
function __construct($name)
{
$this->name = $name;
}
Which will allow you to access it like this:
$bd = new Building("Name");
echo $bd->name;
Addressing your issue in this comment
You get that error because you havent instantiated that variable.
You should do this:
$buildings_HSB = new Building("Name");
echo $buildings_HSB->name;
