When echoing a boolean (true or false), PHP converts it to 1 or <nothing> and displays it. e.g.:
$x = true; echo $x; //displays: 1
$x = false; echo $x; //displays: <nothing>
My Question: Is there a PHP function (if not how to code it) which can display exactly "true" or "false" (and not 1 or nothing), if a variable is a boolean otherwise just display as PHP would normally display it.
I've just been looking to do this but needed to to it inline without a function so I just used :
echo(is_bool($x) ? ($x ? "true":"false"):$x);
Not the easiest to read but gets the job done!
Yes, it can be easily coded like this:
function var_to_str($in)
{
if(is_bool($in))
{
if($in)
return "true";
else
return "false";
}
else
return $in;
}
//Test it now
echo var_to_str("this is string") . PHP_EOL;
echo var_to_str(123) . PHP_EOL;
echo var_to_str(true) . PHP_EOL;
echo var_to_str(false) . PHP_EOL;
This outputs:
this is string
123
true
false
str_replace(array(0, 1), array("No", "Yes"), str_pad(headers_sent(), 1, "0"))
I used headers_sent() just as a BOOLEAN variable.
I had this issue, found this question and the answer was not quite what I needed, so I worked out this:
array_pop(array_keys(array('FALSE' => false,'TRUE' => true), [bool]))
to simply get a printed (echoed) string value for a [bool], replacing [bool] with a variable you know to be a bool.
Thought it might help others who find this question....
