Bug description: ibase_fetch_object returns wrong value for empty string in
database
Description:
------------
Functions ibase_fetch_object, ibase_fetch_row return wrong values when
there is an empty string ('') in firebird table. When there is a 'null'
value in the table this problem doesn't occure.
PHP ver. 5.0.0 works fine, problem is in ver 5.0.4 and higher.
In this example in record number 3 there is value from record number 1
instead of empty string ('').
Reproduce code:
---------------
CREATE TABLE test_table (test_field VARCHAR(10))
Insert 4 records into test_table
rec_no|test_field
------------------
1 | 'test1'
2 | 'test2'
3 | ''
4 | 'test4'
------------------
$sql_string = "SELECT test_field FROM test_table";
$connection = ibase_connect($database, $user, $pass);
$dbo = ibase_query($connection, $sql_string);
while ( $oRow = ibase_fetch_object($dbo) )
{
var_dump($oRow);
}
Expected result:
----------------
{ ["TEST_FIELD"]=> string(5) "test1" }
{ ["TEST_FIELD"]=> string(5) "test2" }
{ ["TEST_FIELD"]=> string(0) "" }
{ ["TEST_FIELD"]=> string(5) "test4" }
Actual result:
--------------
{ ["TEST_FIELD"]=> string(5) "test1" }
{ ["TEST_FIELD"]=> string(5) "test2" }
{ ["TEST_FIELD"]=> string(5) "test1" }
{ ["TEST_FIELD"]=> string(5) "test4" }
