How to Convert Boolean Variables to 'true' or 'false' Strings in PHP?

Conversion of Boolean Variables to String

In PHP, converting Boolean values to strings can be a simple but crucial task. Consider the scenario where you have a Boolean variable, such as:

$res = true;

And you want to convert it to a string in the format of "true" or "false", rather than "0" or "1". This is often necessary for scenarios like displaying values or saving them in specific formats.

Failed Attempts

You may have attempted methods like:

$converted_res = string($res);
$converted_res = String($res);

However, these functions do not exist in PHP.

Solution: Conditional Assignment

The simplest solution is to use conditional assignment, leveraging the ternary operator:

$converted_res = $res ? 'true' : 'false';

This expression evaluates the Boolean value of $res. If $res is true, it assigns the string "true" to $converted_res, and if $res is false, it assigns the string "false" instead. This effectively converts the Boolean variable to a string in the desired format.
