Convert null to string

Question

Is it possible to convert null to string with php?

For instance,

$string = null;

to

$string = "null";

Answer 1

Am I missing something here?

if ($string === null) {
    $string = 'null';
}

---

was thinking something shorter...

You can do it in one line, and omit the braces:

if ($string === null) $string = 'null';

You can also use the conditional operator:

$string = ($string === null) ? 'null' : $string;

Your call.

Answer 2

var_export can represent any variable in parseable string.
