It seems PHP 7 changed a bit the way to work with the Interbase module.
Same code on PHP 5.6 works flawlessly.
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.
One example of code can be:
$conx = ibase_pconnect(DB_HOST . ":" . DB_NAME,DB_USER,DB_PWD,DB_CHARACTER)
or die(ibase_errcode() . ' ' . ibase_errmsg());
$conx2 = ibase_pconnect(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'];
}
DB_xxx are defined variables with the users, password, ..... of the
database.
The result it's the same if instead of **ibase_pconnect** we write
**ibase_connect**
If you run that code you won't get nothing and on the apage 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 ....
If we remove the line with the $conx2 all will work perfectly.
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
Interbase module for php7 has a new option which it's generating this
problem ?
