<para>
This is a convenience macro that can be used when passing a static string
to a function that requires a string length argument together with a string.
This saves duplicating the static string in the sourcecode or adding an extra
variable for it.

<title><function>ZEND_STRL</function> example</title>

<![CDATA[
write(0, ZEND_STRL("Hello World!"));

char str[] = "Hello World!";
