PHP Access Modifiers Example

  • public - the property or method can be accessed from everywhere. This is default
  • protected - the property or method can be accessed within the class and by classes derived from that class
  • private - the property or method can ONLY be accessed within the class
<?php  
class parent
{
public $name="websolutionstuff";
function_display()
{
echo $this->name."<br/>";
}
}
class child extends parent
{
function show()
{
echo $this->name;
}
}
$obj= new child;
echo $obj->name."<br/>";
$obj->function_display();
$obj->show();
