DESCRIPTION:
-----------
1. I can't make simple query with params (with placeholders "?" in SQL).
Then i call ibase_query without placeholders or ibase_prepare - there are
not any errors, all works fine.

But when i try make query similar to
"INSERT INTO TABLE1 (FIELD1) VALUES ( ? )", then ibase_query or
ibase_execute crash script or server - there are no response or an error
unknown responded.

I can work without placeholders, simple by placing param values into
SQL, but not with BLOBs

if i try to place $blob_id_str directly into SQL
"INSERT INTO TABLE2(BLOB1) VALUES ('$blob_id_str')"
Interbase returns error "unexpected end of command"

2. In some queries, with MANY result fields, some fields does not contains
correct values.

3. Why many ib-functions are not documented yet? Does it's means that these
functions is untested and bugfull?

SCRIPT:
--------
<html><body>
test
<hr>
<?
    $test_base = "lin:/opt/interbase/db/php.gdb";
    ibase_connect($test_base, "sysdba", "masterkey");
    ibase_query(
        "drop table test_a");
    ibase_commit();
    ibase_query(
        "create table test_a (
            id int not null primary key,
            memo blob
            )");
    ibase_commit();

    ibase_query("insert into test_a(id) values(0);");
    /////// OK HERE //////////////

   
    $q = ibase_prepare("insert into test_a(id) values ( ? )");
    echo $q;
    /////// OK HERE //////////////


    $five = 5;
    ibase_execute($q, $five);
    /////// CRASH HERE //////////////

[PHP]

;;;;;;;;;;;;;;;;;;;
; About this file ;
;;;;;;;;;;;;;;;;;;;
; This file controls many aspects of PHP's behavior.  In order for PHP to
; read it, it must be named 'php.ini'.  PHP looks for it in the current
; working directory, in the path designated by the environment variable
; PHPRC, and in the path that was defined in compile time (in that order).
; Under Windows, the compile-time path is the Windows directory.  The
; path in which the php.ini file is looked for can be overriden using
; the -c argument in command line mode.
;
; The syntax of the file is extremely simple.  Whitespace and Lines
; beginning with a semicolon are silently ignored (as you probably guessed).
; Section headers (e.g. [Foo]) are also silently ignored, even though
; they might mean something in the future.
;
; Directives are specified using the following syntax:
; directive = value
; Directive names are *case sensitive* - foo=bar is different from FOO=bar.
;
; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one
; of the INI constants (On, Off, True, False, Yes, No and None) or an expression
; (e.g. E_ALL & ~E_NOTICE), or a quoted string ("foo").
;
; Expressions in the INI file are limited to bitwise operators and parentheses:
; |             bitwise OR
; &             bitwise AND
; ~             bitwise NOT
; !             boolean NOT
;
; Boolean flags can be turned on using the values 1, On, True or Yes.
; They can be turned off using the values 0, Off, False or No.
;
; An empty string can be denoted by simply not writing anything after the equal
; sign, or by using the None keyword:
;
;   foo =           ; sets foo to an empty string
;   foo = none      ; sets foo to an empty string
;   foo = "none"    ; sets foo to the string 'none'
;
; If you use constants in your value, and these constants belong to a dynamically
; loaded extension (either a PHP extension or a Zend extension), you may only
; use these constants *after* the line that loads the extension.
;
; All the values in the php.ini-dist file correspond to the builtin
; defaults (that is, if no php.ini is used, or if you delete these lines,
; the builtin defaults will be identical).

This is hopefully fixed in CVS. Please replace ext/interbase/interbase.c with
http://cvs.php.net/viewcvs.cgi/~checkout~/php4/ext/interbase/interbase.c?rev=1.45
and recompile. And please also tell whether it worked or not...
 [2000-10-27 22:40 UTC] jah@php.net
No feedback, but as 1. is the same problem as in #7117 that was confirmed to
be fixed by reporter, closing. (Not enough information to do anything to 2.)
