That's partaially incorrect. PHP streams are not always binary safe by
default, at least on windows (linux has no 'b' but for API
compatibility reasons afair).

Unless you specify the binary mode explicitly. A common problem is to
run under cgi, cli or apache on windows, the default mode may differ
(apache for example is/was not binary safe)
