How to configure the stack depth of traces in PHP applications?

The default stack depth of traces is 15. You can change this by modifying the zpa.stack_depth directive in the zpa.ini (Linux) or php.ini (Windows).

Default configuration:
  1. In the zpa.ini (Linux) or php.ini (Windows),
zpa.stack_depth = 15
Note: The maximum allowed value is 30.

To modify the stack depth for a specific application, update the .htaccess (Linux) or .user.ini (Windows).

    In the .htaccess file (Linux):
php_value zpa.stack_depth 15
    In the .user.ini file (Windows),
zpa.stack_depth = 15
Note: 15 is a default number in the above mentioned commands. You can specify the stack depth required (<30)
