How Can I Efficiently Echo Boolean Values as 'true' or 'false' in PHP?

PHP Echoing Boolean Values as False or True

Consider a scenario where you have a boolean variable, $bool_val, and you want to print "false" if it's false. Using echo $bool_val won't produce any output, while echo (bool)true will print "1." Is there a more efficient way to handle this without resorting to an if statement?

Solution:

For a comprehensive solution, use the following ternary operator:

echo $bool_val ? 'true' : 'false';

This approach assigns "true" to the variable if $bool_val is true and "false" otherwise. Consequently, echoing this modified variable produces the desired output.

Enhanced Solution for False-Value Visibility:

If you desire output only when $bool_val is false, employ the following ternary operator:

echo !$bool_val ? 'false' : '';

Here, !$bool_val evaluates to true when $bool_val is false, resulting in the string "false" being echoed. Otherwise, an empty string is echoed, ensuring that false values are highlighted without cluttering the output when true.
