Bug description:Impossibility of creatiing multiple connections to Interbase with php 7.0
Description:
------------
If you have one open link to an Interbase/Firebird database and you open
**another** one to the same database the first link it's closed.
On my php.ini I have this (exactly the same than on PHP 5.6):
ibase.allow_persistent = 1
; Maximum number of persistent links. -1 means no limit.
ibase.max_persistent = -1
; Maximum number of links (persistent + non-persistent). -1 means no
limit.
ibase.max_links = -1
The same script below was running perfectly on PHP 5.6
NikiC on StackOverflow writed this:
In particular, I don't think this line is correct:
lxr.php.net/xref/PHP_MASTER/ext/interbase/interbase.c#943 This
zend_list_close should probably be a zend_list_delete, otherwise it will
simply always destroy the resource.

Regards,
Test script:
---------------
// DB_xxx are defined variables with the users, password, ..... of the
database.
// We have the same problem if we use ibase_pconnect or ibase_connect
$conx = ibase_connect(DB_HOST . ":" .
DB_NAME,DB_USER,DB_PWD,DB_CHARACTER) or die(ibase_errcode() . ' ' .
ibase_errmsg());
$conx2 = ibase_connect(DB_HOST . ":" .
DB_NAME,DB_USER,DB_PWD,DB_CHARACTER) or die(ibase_errcode() . ' ' .
ibase_errmsg());
$sql = 'SELECT something from somewhere';
$query = ibase_query($conx, $sql);
while ($row = ibase_fetch_assoc($query)) {
echo $row['something'];
}
Expected result:
----------------
$conx should keep the database connection instead of be closed.
Actual result:
--------------
The test script should not write nothing, but on the error log you will
see something like:
supplied resource is not a valid Firebird/InterBase link resource in
....
ibase_fetch_assoc(): Dynamic SQL Error SQL error code = -504 Invalid
cursor reference Cursor is not open ....
It seems $conx has been closed when creating the $conx2 connection.
