Yes, you probably should. If you would spend about 30 seconds to think about it you should be able to figure it out. And if you can't, then sad as it may be, you probably should go do something else. The document says: --assign-params --string-lens By default, function proto 'void foo(string bar)' creates the following: ... zval **bar; ... (zend_get_parameters_ex() called in the middle...) convert_to_string_ex(bar); Specifying both of these options changes the generated code to: ... zval **bar_arg; int bar_len; char *bar = NULL; ... (zend_get_parameters_ex() called in the middle...) convert_to_string_ex(bar_arg); bar = Z_STRVAL_PP(bar_arg); bar_len = Z_STRLEN_PP(bar_arg); See how the parameters are assigned to variables? Hence --assign-params And see how the strlen is assigned to the bar_len variable? Hence --string-lens -Rasmus
