Difference between constructors

Question

Not really sure how to search this, but is there really a difference between these two?

$t = new Test();
// vs...
$t = new Test;

Thanks guys, for pointing out the dupes. They didn't show up when i was searching! — Ascherer, Sep 05 '13 at 17:23
I always request the use of () an instantiation is a method call and so should mirror other function / method calls in your code. no real difference operationally though. — Gavin, Sep 05 '13 at 18:26

There are generally accepted rules and they must adhere to.

$t = new Test();

True choise

This convention is most likely inherited from Java, which PHP attempts to emulate in some ways, however "true choise" does not make much sense. Could you please clarify ? – SirDarius Sep 05 '13 at 17:15

There is no difference. The __construct() method is executed with both.

There is no differance

Look here:

<?php

class Test {
    function printTest() {
        echo "Test";    
    }
}

$t = new Test();
echo $t->printTest();
// vs...

$t = new Test;
echo $t->printTest();

?>

Output:

Test //from Test()
Test //from Test

If the __construct method needs to take in some parameters then you should use

$t = new Class('Param1','Param2');

If it doesn't need to take any parameters then there is no difference between using

$t = new Class;

OR

$t = new Class();
