Description
The method you are trying to call is not defined, which can result in a fatal error.
This issue can be raised for any of the following cases:
- There's a spelling mistake in the method call.
- The method is not defined in either the class or its ancestors.
- You are trying to call a private method from a parent class.
- You are attempting to access an improperly instantiated object or an undefined variable.
- You are trying to use the return value of a method that returns
void.
Bad practice
class User
{
public function printName()
{
echo $this->getName(); // getName() doesn't exist.
}
}
class User
{
private function getName()
{
return 'John Doe';
}
}
class Admin extends User
{
public function printName()
{
echo $this->getName(); // `getName()` is private
}
}
class Admin
{
public function printName()
{
$user = new User(); // class `User` doesn't exist
echo $user->getName();
}
}
class User
{
private $name;
public function setName()
{
$this->name = 'Anonymous';
}
public function printName()
{
$name = $this->setName(); // the "setName" method doesn't return anything
echo $name; // this will print nothing, because $name is NULL
}
}
Recommended
class User
{
public function printName()
{
echo $this->getName();
}
public function getName()
{
return 'John Doe';
}
}
class User
{
protected function getName()
{
return 'John Doe';
}
}
class Admin extends User
{
public function printName()
{
echo $this->getName();
}
}
class User
{
public function getName()
{
return 'John Doe';
}
}
class Admin
{
public function printName()
{
$user = new User();
echo $user->getName();
}
}
