As it is, `::seek(0)` sets the file pointer to the beginning of the
file, but `::seek($n)` where `$n > 0` sets the file pointer to the
beginning of the following line, having line `$n` already read into the
line buffer. This is pretty inconsistent; we fix it by always seeking
to the beginning of the line.
We also add a test case for the duplicate bug #46569.
Closes GH-6434.
Make strspn($str1, $str2, $offset, $length) behaviorally
equivalent to strspn(substr($str1, $offset, $length), $str2)
by not throwing for out of bounds offset.
There have been two reports that this change cause issues,
including bug #80285.
mb_ereg()/mb_eregi() currently have an inconsistent return value
based on whether the $matches parameter is passed or not:
> Returns the byte length of the matched string if a match for
> pattern was found in string, or FALSE if no matches were found
> or an error occurred.
>
> If the optional parameter regs was not passed or the length of
> the matched string is 0, this function returns 1.
Coupling this behavior to the $matches parameter doesn't make sense
-- we know the match length either way, there is no technical
reason to distinguish them. However, returning the match length
is not particularly useful either, especially due to the need to
convert 0-length into 1-length to satisfy "truthy" checks. We
could always return 1, which would kind of match the behavior of
preg_match() -- however, preg_match() actually returns the number
of matches, which is 0 or 1 for preg_match(), while false signals
an error. However, mb_ereg() returns false both for no match and
for an error. This would result in an odd 1|false return value.
The patch canonicalizes mb_ereg() to always return a boolean,
where true indicates a match and false indicates no match or error.
This also matches the behavior of the mb_ereg_match() and
mb_ereg_search() functions.
This fixes the default value integrity violation in PHP 8.

Remove ldap_control_paged_result and ldap_control_paged_result_response
which have been deprecated in PHP 7.4, in favor of new $controls
parameters for ldap request functions.
Disabling output compression for images has served to fix bug #16109,
where zlib compressed images apparently have caused issues with
Navigator 4. This shouldn't be an issue with somewhat contemporary
browsers. Other than that, this is an arbitrary restriction – why
don't we disable the compression for some other media types as well
(e.g. video/* and audio/*)? All in all, we should leave that decision
to userland.
Closes GH-6198.
`odbc_connect()` should not reuse persistent connections, since that
prohibits multiple concurrent connections, which are occasionally
desireable. We fix that by no longer looking for already cached
connections when `odbc_connect()` is called, and instead creating a new
connection instead.
Closes GH-6223.
One strange feature of SplFixedArray was that it could not be used in nested foreach
loops. If one did so, the inner loop would overwrite the iteration state of the outer
loop.
To illustrate:
$spl = SplFixedArray::fromArray([0, 1]);
foreach ($spl as $a) {
foreach ($spl as $b) {
echo "$a $b";
}
}
Would only print two lines:
0 0
0 1
Use the new InternalIterator feature which was introduced in ff19ec2df3 to convert
SplFixedArray to an Aggregate rather than Iterable. As a bonus, we get to trim down
some ugly code! Yay!
Both of these functions are well-defined when used with a single
array argument -- rejecting this case was an artificial limitation.
This is not useful when called with explicit arguments, but removes
edge-cases when used with argument unpacking:
// OK even if $excludes is empty.
array_diff($array, ...$excludes);
// OK even if $arrays contains a single array only.
array_intersect(...$arrays);
This matches the behavior of functions like array_merge() and
array_push(), which also allow calls with no array or a single
array respectively.
Closes GH-6097.
RC4 is considered insecure, and it's not possible to change the
default of these functions. As such, require the method to be
passed explicitly.
Closes GH-6093.
crypt() without salt generates a weak $1$ MD5 hash. It has been
throwing a notice since 2013 and we provide a much better alternative
in password_hash() (which can auto-generate salts for strong
password hashes), so keeping this is just a liability.
If we do not specify the exact version of the .NET framework to use,
the default CLR is loaded, which is typically CLR 2, which is very old.
Therefore, we introduce a `PHP_INI_SYSTEM` setting, which allows users
to choose the desired .NET framework version. The value of the setting
are the first three parts of the framework's version number, separated
by dots, and prefixed with "v", e.g. "v4.0.30319". If the value of the
INI setting is `NULL` (the default) or an empty string, the default CLR
is used.
Internally, we switch from the most generic `CoCreateInstance()` to
`CorBindToRuntime()` which is implemented in mscoree.dll. To avoid the
hard dependency to that library, we load dynamically.
So this fix is supposed to be fully backwards compatible.
Closes GH-5949
User-defined functions can't have multiple parameters with the same name.
Don't do that for var_dump/debug_zval_dump.
