To call the constructor we now only store the CE and a HashTable for the arguments.
This reduces the size of the _pdo_stmt_t struct from 320 bytes to 232 bytes.
Moreover, this now means that the constructor argument array follows the usual CUFA semantics.
This change is a BC break, as string keys now act like named arguments.
Moreover, the automatic wrapping of by-value arguments for by-ref parameters has been dropped, and the usual E_WARNING is now emitted in those cases.
The do_fetch() is heavily refactored to simplify the execution flow, which also makes it easier to understand.
Additionally we add a new bitflag in_fetch to prevent modification of the fetch flags by userland when PDO is fetching from the DB.
This also refactors the internal do_fetch() function to stop doing wonky stuff to handle grouping, which is a feature of fetchAll
Handle PDO_FETCH_KEY_PAIR on its own as GROUP and UNIQUE flags can interfere with it
* Fix php_apache_get_version prototype
Avoids an error with -Werror=strict-prototypes when building the
Apache SAPI.
* Fix -Werror=stringop-truncation in pdo_raise_impl_error
* Note pdo_error_type BC break
1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.

PDO implement half of this, but this functionality is generally
useful. Provide these as zend_u64_to_str and zend_i64_to_str to
complement zend_long_to_str.
Instead of requiring the type to be determined in advance by the
describer function and then requiring get_col to return a buffer
of appropriate type, allow get_col to return an arbitrary zval.
See UPGRADING.INTERNALS for a more detailed description of the
change.
This makes the result fetching simpler, more efficient and more
flexible. The general possibility already existed via the special
PDO_PARAM_ZVAL type, but the usage was very inconvenient and/or
inefficient. Now it's possible to easily implement behavior like
"return int if it fits, otherwise string" and to avoid any kind
of complex management of temporary buffers.
This also fixes bug #40913 (our second highest voted bug of all
time, for some reason). PARAM_LOB result bindings will now
consistently return a stream resource, independently of the used
database driver.
I've tried my best to update all PDO drivers for this change, but
some of the changes may be broken, as I cannot test or even build
some of these drivers (in particular PDO dblib and PDO oci).
Fixes are appreciated -- a working CI setup would be even more
appreciated ;)
This has been fixed for PDO SQlite by GH-4313, however the same
issue also applied to PDO MySQL.
Move the column count setting function into the main PDO layer
(and export it) and then use it in both PDO SQLite and PDO MySQL.
Add a get_gc method that can be implemented by drivers, which can
be used to add additional zvals to the GC buffer.
Implement GC support for PDO SQLite callbacks in particular.
Closes GH-6262.
Added new flags that allow skipping param_evt(s) that are not used by drivers,
in a backwards and forward compatible manner. Updated the pgsql, mysql, sqlite
and oci drivers to properly use the new flags. I've left out pdo_dblib, which
doesn't have a param_hook, and pdo_firebird, which seems to be using
PARAM_EVT_NORMALIZE in a wrong context (param type vs event type).
PDO driver constructors are throwing PdoException without setting
errorInfo, so create a new reusable function that throws exceptions
for PDO and will also set the errorInfo. Use this function in
pdo_mysql, pdo_sqlite, and pdo_pgsql.
Driver-specific options get passed to these functions, which are
not part of the pdo_attribute_type enum. Newer GCC versions don't
like that. Accept a simple integr type instead.
