It All Adds Up

$variable = $variable + 1;

Is the same as:

$variable ++;

This method also works for subtraction:

$variable --;

You can also apply a similar method for concocting strings. So instead of:

$mytext = 'Done and Done.';
$mytext = "$mytext And I mean Done!"; // $mytext = 'Done and Done And I mean Done!';

Use this shorthand method of adding another string of text onto the end of the first string:

$mytext = 'Done and Done.';
$mytext .= ' And I mean Done!'; // $mytext = 'Done and Done And I mean Done!';
