Que dois-je faire si Proc_terminate ne peut pas résilier le processus? Causes possibles et analyse des solutions

Iv. Autres alternatives réalisables

• Utilisez POPEN () et EXEC () pour coopérer avec les commandes de kill externes pour gérer les processus.

• Utilisez PCNTL_FORK () (CLI Environment) pour implémenter vous-même la gestion des processus sur Linux.

• Pour les tâches complexes, envisagez d'utiliser un cadre de gestion de processus tels que SuperVisord au lieu de proc_open () .
