Fatal error Using $this when not in object context in D:\xampp\htdocs\test\php\service\FileCommand.php

The general meaning is that $this has no context, because this class is not instantiated.

This error occurs because of the method/property $this, which is used in filecommand.php.

$this is not to be used, but to look at the situation. It is possible to use $this in an instantiated class:

Class person{

private Var $name;

private Var $sex;

Public Function ShowName () {

Echo $this->name;

$this->message ();

}

Public Function message () {

echo "Success";

}

}

If you instantiate the person class and access it directly, you will get the error above, meaning $this there is no context.

Correct usage:

$person = new Person ();

$person. ShowName ();

If you do not want to define the direct use, then you can pass: Person::message (); Note that the inside cannot contain $this
