1.2.225. Constant Conditions¶
If/then structures that have constant condition.
The condition doesn’t change during execution, and the following blocks are always executed or not. This may also lead to an infinite or a null loop.
When this is the case, the condition may be removed, and dead code may be removed. It is advised to remove them, or to make them depend on configuration.
<?php
// static if
if (0.8) {
$a = $x;
} else {
$a = $y;
}
// static while
while (1) {
$a = $x;
}
// static do..while
do {
$a = $x;
} while ('b'. 'c');
// constant for() : No increment
for ($i = 0; $i < 10; ) {
$a = $x;
}
// constant for() : No final check
for ( $i = 0; ; ++$i) {
$a = $x;
}
// static ternary
$a = TRUE ? $x : $y;
?>
