Kill processes for user

To easily kill all processes running under a user

ps -u USER | awk ‘{print $1}’ | xargs kill -9

or

pkill -u USER

replacing USER with the username.

To kill all specific processes such as php running under a user run,

ps -u USER | grep PROCESS |awk ‘{print $1}’ | xargs kill -9

replacing USER with username and PROCESS with php or any other process.
