laravel false turns to true code example

Example: php convert string to boolean

/**
 * Strings always evaluate to boolean true unless they have a
 * value that's considered "empty" by PHP (taken from the
 * documentation for empty):
 * "" (an empty string) evaluates as false.
 * "0" (0 as a string) evaulates as false.
 * If you need to set a boolean based on the text value of a
 * string, then you'll need to check for the presence or
 * otherwise of that value.
 */
$boolean = $string === 'true' ? true: false;
