La licencia PHP es la licencia bajo la que se publica el lenguaje de programación PHP. De acuerdo a la Free Software Foundation es una licencia de software libre no copyleft y una licencia de código abierto según la Open Source Initiative.[1] [2] Debido a la restricción en el uso del término "PHP", no es compatible con la licencia GPL.[1]

Términos[editar]

La licencia PHP está diseñada para incentivar la distribución del código fuente. Se permite la redistribución del contenido licenciado en forma de código fuente o binaria siempre y cuando se cumplan los siguientes requisitos:

  1. Se incluya la declaración de los derechos de autor de la licencia PHP;
  2. La palabra "PHP" no se use en el título de las obras derivadas;
  3. Se incluya el siguiente anuncio bajo cualquier forma en la que se redistribuya el código:
This product includes PHP software, freely available from <http://www.php.net/software/>

La versión 3 del lenguaje PHP usa una licencia dual: el código fuente de esa versión se encuentra disponible bajo la licencia PHP y la GNU General Public License. A partir de la versión 4 de PHP, ésta última dejó de usarse debido a (según los desarrolladores del lenguaje) las restricciones impuestas por el copyleft a la reutilización de los contenidos.[3]

Directrices de software libre de Debian[editar]

De acuerdo a una discusión en la lista Debian legal, aún no se llega a un acuerdo con respecto a aceptar la compatibilidad de la licencia PHP con las directrices de software libre de Debian.[4]
