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

Converting Boolean Variables to Strings in PHP

When working with Boolean variables, it may be necessary to convert them to strings for specific purposes. In PHP, converting a Boolean to a string requires a different approach than simply attempting to use string() or String() functions.

To convert a Boolean variable to a string in the desired format of "true" or "false," the following code snippet demonstrates the simplest approach:

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

In this code, the conditional (ternary) operator is employed. If the Boolean variable $res is true, the expression evaluates to 'true'; otherwise, it evaluates to 'false'. The resulting string is then stored in $converted_res.

For example, if $res is initially assigned true, $converted_res will contain the string "true". Conversely, if $res is set to false, $converted_res will hold the string "false".
