There is absolutely no reason why these should be mentioned in the Boolean section, any more than there is to mention ==, != or any of the other comparison (not comparative) operators. > They are mentioned under Comparative Operators but are > not defined. This is just not true -- they are fully and comprehensively defined in Table 15.4 in that section, alongside all the other comparison operators. > The operator === is mentioned in the strpos section, the > array_search section and possibly the sections covering other > functions that may find a needle in position 0 of a haystack. Yes -- this is a standard piece of text which is included in the definition of all functions that may return Boolean FALSE on failure but another type if successful; not only does it reference the section on Booleans, it also includes the stricture "Use the === operator for testing the return value of this function", where the words "the === operator" are a link to the Comparison Operators page which... well, this is where we came in! This text seems to me to be quite adequate to the job. I might suggest one or two small improvements, such as placing the stricture re === before the reference to the section on Booleans, and perhaps mentioning the !== operator as well, but otherwise I can find no real cause for complaint with it. Additionally, example 1 on the strpos() page even demonstrates exactly how to test the return value of strpos() using ===, so I don't know how much more explicit the manual can be. Cheers!
