What is the php assignment operator?

The most basic form of the assignment operator is "=". The "=" here does not mean "equal", but means assignment. Its function is simply to assign a value to a variable. For example, $A=10 means assigning 10 to $A, so the value of $A is 10.

Of course, this is only the most basic assignment operator. In addition to the most basic "=" assignment operator, we have other forms of assignment operators, which we call compound assignment operators, as shown in the following table

=	Assignment	$a=b	$a=b	Assign the value on the right to the left
=	Add	$a =b	$a=$a b	Add the value on the right to the left
-=	Minus	$a-=b	$a=$a-b	Decrease the value on the right to the left
*=	Multiply	$a*=b	$a=$a*b	Multiply the value on the right by the value on the left
/=	except	$a/=b	$a=$a/b	will The value on the right is divided by the value on the left
.=	connection character	$a.=b	$a=$a.b	Add the characters on the right to the left
%	Get the remainder	$a%=b	$ a=$a %b	Take the remainder of the value on the left and the value on the right
