type casting

[mkooij]

Dear fellow programmers,

I've got a problem with type casting in php.

I've got the the following code ( it's a test so it doesn't do very mutch)

 

<?php
class test{
  function  Casted(string $mysting,int $myint){
  
         echo 'your string is '. $mysting;
         echo 'your integer is '.$myint;


}

}

$myfunction = new test;

$myfunction.Casted('hello world',1234567);


?>

 

The above code generates an error on the line where I try to call the function by saying that the 1st variable does not have the right type... :S

 

does anyone know how ( or if it possible at all) to do the above?

 

Thanks and happy coding!

class ctest{

function  Casted($mysting,$myint){

echo 'your string is '. $mysting;

echo 'your integer is '.$myint;

}

}

 

$myfunction = new ctest();

$a=$myfunction->Casted('hello world',1234567);

In PHP '.' is the concatination operator. You '->' operator '->' for Object->member referencing

It should work fine...

 

try putting

ini_set('error_reporting', E_ALL);

I've got PHP Version 5.1.2

 

 

when I run the code below

<?php

ini_set('error_reporting', E_ALL);

class CTest{

 function  Casted(string $mysting,int $myint){
  
         echo 'your string is '. $mysting;
         echo 'your integer is '.$myint;


}

}

$test = new CTest;
$test->Casted("test",12345);


?> 

 

I get the following fatal error:

 

Fatal error: Argument 1 passed to CTest::Casted() must be an object of class string, called in /var/www/gaatloos/gda_test/cast.php on line 19 and defined in /var/www/gaatloos/gda_test/cast.php on line 6

<?php

ini_set('error_reporting', E_ALL);

class CTest{

 function  Casted($mysting,$myint){
  
         echo 'your string is '. (string)$mysting;
         echo 'your integer is '.(int)$myint;


}

}

$test = new CTest;
$test->Casted("test",12345);


?>

  I still get the message

 

Fatal error: Argument 1 passed to CTest::Casted() must be an object of class string, called in /var/www/gda_test/cast.php on line 19 and defined in /var/www/gda_test/cast.php on line 6

What you are talking about here is type hinting not type casting. Unless you hvae create the objects string and int your code will error because they are not native php objects.

 

A small example...

 

<?php
  
  class a {
    public function test() {
      echo "foo";
    }
  }

  class b {
    public function test(a $a) {
      $a->test();
    }
  }

  $a = new a();
  $b = new b();
  $b->test();

?>
