Jein.

Das ist *C*-Code von PHP *7.x* oder neuer.

Wie man im C-Code sieht, hängt die Verfügbarkeit der Konstante in PHP neben 
der PHP-Version auch von der Version der libcurl ab, mit der PHP compiliert 
wurde.  Sofern die verwendete Version der libcurl 7.47.0 oder neuer war, so 
ist die Konstante ab PHP 7.0 verfügbar.
