I am now learning object oriented php and i face a problem with the magic method named __toString().
There are no calls for that function. Is it similar to other magical function?
If a use it to my class then is it convert all the objects all string or not?
Code-
class MyClass
{
public $prop1 = "I'm a class property!";
public function __construct()
{
echo 'The class "', __CLASS__, '" was initiated!<br />';
}
public function __destruct()
{
echo 'The class "', __CLASS__, '" was destroyed.<br />';
}
public function __toString()
{
echo "Using the toString method: ";
return $this->getProperty();
}
public function setProperty($newval)
{
$this->prop1 = $newval;
}
public function getProperty()
{
return $this->prop1 . "<br />";
}
}
// Create a new object
$obj = new MyClass;
// Output the object as a string
echo $obj;
// Destroy the object
unset($obj);
// Output a message at the end of the file
echo "End of file.<br />";
?>
The output-
The class "MyClass" was initiated! Using the toString method: I'm a class property! The class "MyClass" was destroyed. End of file.
The magic __toString
method is called when an object of that class is getting used as a string:
class Something {
private $whatever;
public function __construct($whatever) {
$this->whatever = $whatever;
}
public function __toString() {
return $this->whatever;
}
}
$obj = new Something("Whatever here!");
echo "Object is $obj"; // Object is Whatever here!
