Assignment Operators (Chapter 5)
Main Lab 4 Page
Assigning values to variables is generally done with the assignment operator (=). However, there are other assignment operators that can edit variables in a more dynamic way.
| Operator | Action |
|---|---|
=
|
Replaces the variable on the left, with the value on the right. |
+=
|
Adds the value on the right, to the variable on the left. |
-=
|
Subtracts the value on the right, from the variable on the left. |
.=
|
Concatenates the value on the right, to the variable on the left. |
These four assignment operators are demonstrated in the following block of PHP code:
Original value is 100
Added a value, now it's 125
Subtracted a value, now it's 113
Final answer: 113 chickens
