[TYPO3-dev] Problems with a deprecated php function

[Ivan Gomez Rodriguez]

Does someboby know if it's possible use call_user_function instead
call_user_method function in TYPO3 core (v.4.12)?,

This change will be rather dangerous or not

Following is the only one place where call_user_func is called in my
intallation

typo3/sysext/cms/tslib/class.tslib_content.php:5697:
       $content = call_user_method($parts[1], $classObj, $content, $conf);

I wish to use exceptions and i can't do that because call_user_method is
deprecated and it have well-known bugs related with exceptions.

A solution could be change this function for any of recommended
functions call_user_func or call_user_func _array

http://es.php.net/manual/en/function.call-user-method.php


Does somebody know if it's possible do that?
Is it the best solution or i could find other problems?

BTH, How do you handle errors in FE?

I think that to print an error message (with echo) when an error happens
 , as in typo3_db is an mistake.

In PHP exists error handlers and to use error handler is much better
than only print an error.

Thanks in advance
