Variable Manipulation
Variables can also be manipulated as in the following example. This works similarly to the prior example and is just a more verbose way of expressing the same statements:
Code:| 1 | //integers |
| 2 | $foo = 0; //creates the variable $foo |
| 3 | $foo = $foo + 2; //increases the value of $foo by 2 |
| 4 | $foo = $foo * 3; //multiplies the value of $foo by 3 |
| 5 | $foo = $foo - 2; //decreases the value of $foo by 2 |
| 6 | $foo = $foo / 2; //divides the value of $foo by 2 |
| 7 | |
| 8 | //strings |
| 9 | $bar = "this is a string"; //creates the variable $bar |
| 10 | $bar = $bar . " additional data"; //append the string with "additional data" |
