Due to an incorrect check, the datetime was never actually set.
To test this we need to write the file using phar, but read the file
using a different method to not get a cached, or a value that's been
transformed twice and is therefore accidentally correct.

The entry.flags was used to check whether the entry has the directory
flag. The flags however were masked to only contain the permissions. We
need to check the mode, before the permission masking, instead of the
flags to check whether it is a directory.

I found this issue using static analysis tools, it reported that the condition was always false.
We can see that flags is assigned in the switch statement above, but a mistake was made in the comparison.

When a tar phar is created, `phar_open_from_fp()` is also called, but
since the file has just been created, none of the format checks can
succeed, so we continue to loop, but must not check again for the
format. Therefore, we bring back the old `test` variable.
Closes GH-9620.
The phar wrapper needs to uncompress the file; the uncompressed file
might be compressed, so the wrapper implementation loops. This raises
potential DOS issues regarding too deep or even infinite recursion (the
latter are called compressed file quines[1]). We avoid that by
introducing a recursion limit; we choose the somewhat arbitrary limit
`3`.
This issue has been reported by real_as3617 and gPayl0ad.

Using php_info_print_table_header() for "Foo: bar" looks odd and out of place,
because the whole line is colored. It is also questionable from a HTML
semantics point of view, because it does not described the columns that follow.
The use of this across extensions is inconsistent. It was part of the skeleton,
but ext/date or ext/json already use a regular row.
Each section of `phpinfo` is titled with an `<h2><a name="module_NAME">NAME</a></h2>` tag. While the `name=module_NAME` attribute allows linking to that section using a URL fragment (e.g `info.php#module_NAME`), it lacks discoverability because the `<a>` tag does not contain an `href` attribute. This is also highlighted in accessibility scans (in Firefox for instance).
This adds a link to the `<a>` tag that links to the URL fragment, fixing the accessibility remark and improving the discoverability of the clickable section titles. Also contains minor CSS changes to account for the dark theme CSS.
Closes GH-9054.

* ext/{opcache,phar,spl,standard}: use zend_string_starts_with()
This adds missing length checks to several callers, e.g. in
cache_script_in_shared_memory(). This is important when the
zend_string is shorter than the string parameter, when memcmp()
happens to check backwards; this can result in an out-of-bounds memory
access.

Previously stripos/stristr would lowercase both the haystack and the
needle to reuse strpos. The approach in this PR is similar to strpos.
memchr is highly optimized so we're using it to search for the first
character of the needle in the haystack. If we find it we compare the
remaining characters of the needle manually.
The new implementation seems to perform about half as well as strpos (as
two memchr calls are necessary to find the next candidate).
- for packed arrays we store just an array of zvals without keys.
- the elements of packed array are accessible throuf as ht->arPacked[i]
instead of ht->arData[i]
- in addition to general ZEND_HASH_FOREACH_* macros, we introduced similar
familied for packed (ZEND_HASH_PACKED_FORECH_*) and real hashes
(ZEND_HASH_MAP_FOREACH_*)
- introduced an additional family of macros to access elements of array
(packed or real hashes) ZEND_ARRAY_ELEMET_SIZE, ZEND_ARRAY_ELEMET_EX,
ZEND_ARRAY_ELEMET, ZEND_ARRAY_NEXT_ELEMENT, ZEND_ARRAY_PREV_ELEMENT
- zend_hash_minmax() prototype was changed to compare only values
Because of smaller data set, this patch may show performance improvement
on some apps and benchmarks that use packed arrays. (~1% on PHP-Parser)
TODO:
- sapi/phpdbg needs special support for packed arrays (WATCH_ON_BUCKET).
- zend_hash_sort_ex() may require converting packed arrays to hash.
