From the documentation:

There are two special-case header calls. The first is a header that starts with the string "HTTP/" (case is not significant), which will be used to figure out the HTTP status code to send.


The optional replace  parameter indicates whether the header should replace a previous similar header, or add a second header of the same type. By default it will replace [...]

But as can be seen below, header fails to replace headers in all cases.

Reproduce code:

Actual result:
As can be seen in the code linked above, header only truly replaces a similar header in the case if the Status is 200, for every other status code (that I've tested) PHP will output a duplicate header which does not conform to CGI spec.
