1.2.643. Lone Blocks¶
Grouped code without a commanding structure is useless and may be removed.
Blocks are compulsory when defining a structure, such as a class, a function or a switch. They are most often used with flow control instructions, like if then or foreach.
Blocks are also valid syntax that group several instructions together, though they have no effect at all. They are unusual enough to confuse the reader.
Most often, it is a ruin from a previous flow control instruction, whose condition was removed or commented. They should be removed.
<?php
// Lone block without artefact
{
$a = 3;
$c = 4;
}
// Lone block with commented out loop
//foreach($a as $b)
{
$b = 1;
}
?>
