• PHP 7.1.3+ is required.
  Currently installed version is: 5.6.40-60+0~20220627.67+debian10~1.gbp1f7ffd

de forma que hauré de configurar Apache amb PHP-FPM perquè faci servir diferents versions de PHP en funció de quina aplicació web es visiti,

Comprovo quines versions de PHP hi ha instal·lades,
