A common way to abbreivate such simple expression, is using shorthand operators like: | |||
* += | |||
* -= | |||
* *= | |||
* /= | |||
For example: | |||
<syntaxhighlight lang="php"> | |||
if (x < 5) { | |||
x += 2; # means x = x + 2 | |||
y += 1; # means y = y + 1 | |||
} | |||
</syntaxhighlight> | |||
Now lets pretend that we still want to increase x by 2 if it less than 5, and if it is 5 or more we want to add 1 to it. We use else. | Now lets pretend that we still want to increase x by 2 if it less than 5, and if it is 5 or more we want to add 1 to it. We use else. | ||
