1.2.115. Cast To Boolean¶
This expression may be reduced to casting to a boolean. This makes the code more readable, and adapt the type of the value to its usage.
<?php
$variable = $condition == 'met' ? 1 : 0;
// Same as
$variable = (bool) $condition == 'met';
$variable = $condition == 'met' ? 0 : 1;
// Same as (Note the condition inversion)
$variable = (bool) $condition != 'met';
// also, with an indentical condition
$variable = !(bool) $condition == 'met';
// This also works with straight booleans expressions
$variable = $condition == 'met' ? true : false;
// Same as
$variable = $condition == 'met';
?>
1.2.115.1. Suggestions¶
Remove the old expression and use
(bool)operator insteadChange the target values from true/false, or 0/1 to non-binary values, like strings or integers beyond 0 and 1.
