ZEND_API provides parameter return method

Set the return value and end the function Set the return value Macro return type and parameters
RETURN_LONG(l) RETVAL_LONG(l) Integer
RETURN_BOOL(b) RETVAL_BOOL(b) Boolean number (1 or 0)
RETURN_NULL() RETVAL_NULL() NULL
RETURN_DOUBLE(d) RETVAL_DOUBLE(d) Floating point number
RETURN_STRING(s, dup) RETVAL_STRING(s, dup) String. If dup is 1, the engine will call estrdup() to repeat s, using copy. If dup is 0, use s
RETURN_STRINGL(s, l, dup) RETVAL_STRINGL(s, l, dup) a string value of length l. Same as the previous macro, but faster because the length of s is specified.
RETURN_TRUE RETVAL_TRUE Returns boolean true. Notice that this macro has no parentheses.
RETURN_FALSE RETVAL_FALSE Returns boolean false. Notice that this macro has no parentheses.
RETURN_RESOURCE(r) RETVAL_RESOURCE(r) Resource handle.

The above introduces the macro of the PHP expansion return value in the zend engine, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
