Question

Hi, I’m trying to write code to achieve php polymorphism. I don’t know where there is a mistake in the code. It shows the error in “Fatal error: Cannot redeclare Sample::a() “. Here is my code. Kindly solve this problem.

 <?php
 class Sample
{
public function a()
{
 echo "hi";
}
public function a($chr)
{
 for ($chr=0;$chr<10;$chr++)
 echo $chr;
}
 public function a($b,$c)
 {
for($g=$b;$g<$c;$g++)
echo $g

$s=new Sample();

$s->a($chr);
$s->a(1,10);
