How do I convert the value of a PHP variable to string?

I was looking for something better than concatenating with an empty string:

$myText = $myVar . '';

Like the ToString() method in Java or .NET.

Can use the casting operators:

$myText = (string)$myVar;

There are more details for string casting and conversion in the Strings section of the PHP manual, including special handling for booleans and nulls.
