Bug description:Implemented abstract function with additional parameter having
default value
Description:
------------
Implemented abstract function with additional parameter having default
value
doesn't cause any error.
Will output:
I am the first arg. I am the additional arg.
I am the first arg. I am the additional arg default value.
If no default value the script crash.
Test script:
---------------
<?php
abstract class AbstractMother
{
public abstract function methodWithOneArg( $arg );
}
class ConcreteChild extends AbstractMother
{
public function methodWithOneArg($arg, $arg2="I am the additional arg
default value.")
{
echo $arg." ".$arg2 ;
}
}
$child = new ConcreteChild() ;
$child->methodWithOneArg( "I am the first arg.", "I am the additional
arg.") ;
echo "<br>" ;
$child->methodWithOneArg("I am the first arg.") ;
Expected result:
----------------
FATAL ERROR thrown
Actual result:
--------------
Just works, addition of a third argument is ignored:
<?php
class ConcreteChild2 extends AbstractMother
{
public function methodWithOneArg($arg, $arg2="I am the additional arg
default value.", $arg3="I am another arg default value.")
{
echo $arg." ".$arg2." ".$arg3 ;
}
}
echo "<br>" ;echo "<br>" ;
$child2 = new ConcreteChild2() ;
$child->methodWithOneArg( "I am the first arg.", "I am the additional
arg.", "I am the other additional arg") ;
echo "<br>" ;
$child->methodWithOneArg( "I am the first arg.", "I am the additional
arg.") ;
echo "<br>" ;
$child->methodWithOneArg("I am the first arg.") ;
?>
Will output:
I am the first arg. I am the additional arg.
I am the first arg. I am the additional arg.
I am the first arg. I am the additional arg default value.
