    $reallyLongConditionThatIDontFeelLikeMakingUpRightNowSoIllJustUseAVariableNameNumberTwo) {

# Versus:

if ($reallyLongConditionThatIDontFeelLikeMakingUpRightNowSoIllJustUseAVariableNameNumberOne -and
    $reallyLongConditionThatIDontFeelLikeMakingUpRightNowSoIllJustUseAVariableNameNumberTwo)
{
    Do-Something
}

# In the first version, the second line of the conditional is indented the same amount as the code
# inside the curly braces, making it harder to spot the break.  Curly brace on its own line is one way
# to address this.  Some others:

# Double indent of multi-line conditions, creates visual separation between the condition
# and the beginning of the body inside the curly brace.

if ($reallyLongConditionThatIDontFeelLikeMakingUpRightNowSoIllJustUseAVariableNameNumberOne -and
        $reallyLongConditionThatIDontFeelLikeMakingUpRightNowSoIllJustUseAVariableNameNumberTwo) {

}

# Just don't write long conditions like that in the first place. :P  Place that code into its own
# function, which is a good idea anyway, for code clarity.
