Bug description:comparing 2 strings, when 1 string is numeric
Description:
------------
Link: http://www.php.net/manual/en/types.comparisons.php
It's written that "If (..) the comparison involves numerical strings, then
each string is converted to a number and the comparison performed
numerically." After reading this, some (e.g., me) may think that both
strings are converted if *any* of involved strings is numeric, so '2abc' ==
'2' would have to return true rather than false.
To avoid such misunderstandings, I would advise to change this sentence to
something like this:
* "If you compare a number with a string, a string with a number or a
numerical string with another numerical string, then each string is
converted to a number and the comparison performed numerically."
* "If you compare a number with a string, a string with a number or two
numerical strings, then each string is converted to a number and the
comparison performed numerically."
