Readability of code blocks
Related lines of code should be grouped into blocks, seperated from each other to keep readability as high as possible. The definition of "related" depends on the code :)
For example:
<?php
if ($foo) {
$bar = 1;
}
if ($spam) {
$ham = 1;
}
if ($pinky) {
$brain = 1;
}
?>
is a lot easier to read when seperated:
<?php
if ($foo) {
$bar = 1;
}
if ($spam) {
$ham = 1;
}
if ($pinky) {
$brain = 1;
}
?>
Return early
To keep readability in functions and methods, it is wise to return early if simple conditions apply that can be checked at the beginning of a method:
<?php
function foo($bar, $baz)
{
if ($foo) {
//assume
//that
//here
//is
//the
//whole
//logic
//of
//this
//method
return $calculated_value;
} else {
return null;
}
}
?>
It's better to return early, keeping indentation and brain power needed to follow the code low.
<?php
function foo($bar, $baz)
{
if (!$foo) {
return null;
}
//assume
//that
//here
//is
//the
//whole
//logic
//of
//this
//method
return $calculated_value;
}
?>
