Can someone explain me how to use "$this=>"

Question

I can't understand the thing $this in php someone help please

Answer 1

$this is a predefined variable which is used to calling a object.
for example

<?php
class num{
public $a=5;
public function show(){
echo $this->a;
}

}
$ob=new num ();
$ob->show ();
?>

Answer 2

$this is a class member and it is mainly used to refer properties/objects of a class.

To learn about the $this variable is to ask PHP what it is. 

For example:
print is_array($this);
print is_object($this);

Hi! When working with classes $this is reference to the current object. in other if you've declare a public property $name, to access it you need to use $this->name. meaning your refere to the property $name.

It cannot be use outside of a class, nor in a static method in which you will have to use self:: instead.

Let say you have a class:

<?php
class Person
{
// a property $name = 'John';
public $name;

// then for instance you have a function that return a name.
public function getName()
{
//to access $name, use $this.
return $this->name; // will return John, if you use $name, an error will be thrown, $name is undefined.
}
}

// Same as if you instatiate the class Person
$name = new Person();
// to get the name you need to call getName method, we then use $name as it an object of the class Person thus can access it public method

$name->getName() // will return John, here $name act like $this.

To access an object (not static) in a class you use $this, and self:: if it's static and to access outside of the class you instantiate a new object $newObject and use it to access methods and property of a class $newObject->theObjectMethod().
