How can PHP effectively handle boolean values received from CLI commands, like in the case of querying the state of a guest WLAN?

When querying the state of a guest WLAN through CLI commands, boolean values are often returned as strings like "true" or "false". To effectively handle these values in PHP, you can use a simple conditional check to convert these strings into actual boolean values that can be easily used in your code.

// Example CLI command output
$guestWlanState = "true";

// Convert string to boolean value
$guestWlanState = filter_var($guestWlanState, FILTER_VALIDATE_BOOLEAN);

// Check the state of the guest WLAN
if ($guestWlanState) {
    echo "Guest WLAN is enabled";
} else {
    echo "Guest WLAN is disabled";
}
