How to Convert Boolean to String

Question

I have a boolean variable which I want to convert to a string

$res = true;

I need it the converted value to also be in the format "true" "false" not "0" "1"

$converted_res = "true";
$converted_res = "false";

I've tried:

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

but it tells me string and String are not recognized functions. How do I convert this boolean to a string in the format "true" or "false" in php?

Answer 1

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

Answer 2

You use strval() or (string) to convert to string in PHP. However, that does not convert boolean into the actual spelling of "true" or "false" so you must do that by yourself. Here's an example function:

function strbool($value)
{
    return $value ? 'true' : 'false';
}
echo strbool(false); // "false"
echo strbool(true); // "true"

Answer 3

See var_export
