 Dropping brackets saves space and time in your code.
 


 Much like using shortcuts when writing else functions, you can also save some characters in the code by dropping the brackets in a single expression following a control structure. Evolt.org has a

 showcasing a bracket-less structure.

4. Drop those Brackets

Dropping brackets saves space and time in your code.

Much like using shortcuts when writing else functions, you can also save some characters in the code by dropping the brackets in a single expression following a control structure. Evolt.org has a

handy example

showcasing a bracket-less structure.

view plain

copy to clipboard

print

?

if

(

$gollum

==

'halfling'

) {

$height

--;

}


 if ($gollum == 'halfling') {

$height --;

}

This is the same as:

view plain

copy to clipboard

print

?

if

(

$gollum

==

'halfling'

)

$height

--;


 if ($gollum == 'halfling') $height --;

You can even use multiple instances:

print

if

(

$gollum

==

'halfling'

)

$height

--;

else

$height

++;

if

(

$frodo

!=

'dead'

)

echo

'Gosh darnit, roll again Sauron'

;

foreach

(

$kill

as

$count

)

echo

'Legolas strikes again, that makes'

.

$count

.

'for me!'

;
