The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
This patch normalizes the filter extension version in the php info
output. Instead of the Git attributes ident blob object name from Git
repository only extension status is displayed.
A set of hard-coded thousand separator characters (presently, `',.`) is
somewhat limited (users may prefer other separators, such as spaces or
underscores), as well as somewhat too liberal (arbitrary combinations
of different thousand separators are presently possible). Therefore we
introduce a `thousand` option analogous to `decimal`, which allows to
define the desired thousand separators as non-empty string, defaulting
to `',.`. While we easily could support empty strings here as well,
that would not make much sense, since this behavior can more easily be
accomplished by not setting the `FILTER_FLAG_ALLOW_THOUSAND` flag in
the first place.
This reverts commit a2c7c46d5e.
Since apparently there have been some mistakes in this commit, and it's
not clear yet how to solve them, we're reverting for now.
PHP requires integer typehints to be written "int" and does not
allow "integer" as an alias. This changes type error messages to
match the actual type name and avoids confusing messages like
"must be of the type integer, integer given".
`FILTER_FLAG_SCHEME_REQUIRED` and `FILTER_FLAG_HOST_REQUIRED` are
implicitly used for `FILTER_VALIDATE_URL` so there is no need to
specify them explicitly.
Cf. https://bugs.php.net/75442.
...from FILTER_VALIDATE_BOOLEAN, FILTER_NULL_ON_FAILURE
The remainer of the fix would require the filter functions to only
convert to string when it makes sense for that particular filter.
