How do I get around ini_set disabled when trying to autoload [duplicate]

Question

This question already has answers here:

Why is unserialize_callback_func needed when spl_autoload_register is already used? (2 answers)

Closed 9 years ago.

I'm writing a WordPress plugin that uses Raven, which uses autoload in the following way:

ini_set('unserialize_callback_func', 'spl_autoload_call');
spl_autoload_register(array(new self, 'autoload'));

However, some users of the plugin have ini_set disabled by their host providers, and an error gets thrown when the plugin is activated:

Warning: ini_set() has been disabled for security reasons in...

Is there a way I can get around using ini_set in this case?

I guess my real question is if ini_set necessary when using spl_autoload_register or not?

Answer 1

This answer states that you probably don't need to set unserialize_callback_func anymore when using spl_autoload_register().
