First of all, please note that token expiration and revoking are two different things.

1. Expiration only happens for web apps, not for native mobile apps, because native apps never expire.
2. Revoking only happens when (1) uses click the logout button on the website or native Apps;(2) users reset their passwords; (3) users revoke their tokens explicitly in the administration panel.

1. How to hadle JWT expiration

A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.

Quoted from JWT RFC:

Command Execution

exec           - Returns last line of commands output
passthru       - Passes commands output directly to the browser
system         - Passes commands output directly to the browser and returns last line
shell_exec     - Returns commands output
\`\` (backticks) - Same as shell_exec()
popen          - Opens read or write pipe to process of a command
proc_open      - Similar to popen() but greater degree of control
pcntl_exec - Executes a program
