Description:
------------
My opinioin to #41345 tony2001@php.net comment:

I think, that this is bug.
I have the similar experience - after upgrading from PHP 5.2.1
to PHP 5.2.2 I cannot work with filled blob fields.
Warnings: 
ibase_blob_info() - unrecognized BLOB field in ...

Downgrade back to 5.2.1 fixes the problem.
So I expect, that this is bug only in 5.2.2.

Tested on the following two cases:
1. Win2000Pro, Apache 2.3, php as ISAPI module, database Firebird 1.53
2. WinXPPro, Apache 2.4, php as CGI, database Firebird 1.53

Tom

Reproduce code:
---------------
  //... $con= ...  connecting to db was before....  
  $query=ibase_query($con,"SELECT SOMEBLOBFIELD FROM TB_WITHBLOB");
  $record=ibase_fetch_row($query);  
  $blobinfo = ibase_blob_info($record[0]); //<-- warning Warning: ibase_blob_info() [function.ibase-blob-info]: Unrecognized BLOB ID in ....   
  //some code bellow...


Expected result:
----------------
I expect no warning :-)

Actual result:
--------------
arning Warning: ibase_blob_info() [function.ibase-blob-info]: Unrecognized BLOB ID in...

Hi,

I agree with IDVIS, the Interbase Blob function seems to be unusable, I get the same error "Unrecognized BLOB....".

I had to revert back to PHP4 while in the process migrating my project to PHP5.

I'm using Windows XP + FB 2.0.1 + Xitami.

Please help :P

Maybe this change http://cvs.php.net/viewvc.cgi/php-src/ext/interbase/ibase_blobs.c?r1=1.12&r2=1.13 broked ibase_blob_*() functionality?

We have the same issue, after upgrading from 5.2.0 to 5.2.3.

Running in Apache 2, SuSE 10.2
 [2007-07-12 19:16 UTC] quipo@php.net

PHP Bug? 

See below that the codes is differs from version 5.2.1 to earlier:


The PHP 5.2.1 code 

char *_php_ibase_quad_to_string(ISC_QUAD const qd) /* {{{ */
{
	char *result = (char *) emalloc(BLOB_ID_LEN+1);

	/* shortcut for most common case */
	if (sizeof(ISC_QUAD) == sizeof(ISC_UINT64)) {
		sprintf(result, "0x%0*" LL_MASK "x", 16, *(ISC_UINT64*)(void *) &qd);
	} else {
		ISC_UINT64 res = ((ISC_UINT64) qd.gds_quad_high << 0x20) | qd.gds_quad_low;
		sprintf(result, "0x%0*" LL_MASK "x", 16, res);
	}
	result[BLOB_ID_LEN] = '\0';
	return result;
}
/* }}} */




The PHP 5.2.3 or 5.2.2

char *_php_ibase_quad_to_string(ISC_QUAD const qd) /* {{{ */
{
	char *result;

	/* shortcut for most common case */
	if (sizeof(ISC_QUAD) == sizeof(ISC_UINT64)) {
		spprintf(&result, BLOB_ID_LEN+1, "0x%0*" LL_MASK "x", 16, *(ISC_UINT64*)(void *) &qd);
	} else {
		ISC_UINT64 res = ((ISC_UINT64) qd.gds_quad_high << 0x20) | qd.gds_quad_low;
		spprintf(&result, BLOB_ID_LEN+1, "0x%0*" LL_MASK "x", 16, res);
	}
	return result;
}
/* }}} */

The temporary solution:

find php\ext\php_interbase.dll in php V5.2.1

copy this file to php5.2.3\ext\ overwrite the new version file

I am using php V5.2.3 + apache2.2.4 + WinxpProSP2

test it sucessfully

Please try using this CVS snapshot:

  http://snaps.php.net/php5.2-latest.tar.gz
 
For Windows (zip):
 
  http://snaps.php.net/win32/php5.2-win32-latest.zip

For Windows (installer):

  http://snaps.php.net/win32/php5.2-win32-installer-latest.msi

Should be fixed in the snap.
 [2007-08-03 10:33 UTC] idvis at seznam dot cz 
I tried this snapshot
http://snaps.php.net/win32/php5.2-win32-latest.zip
and unfortunately I must say,
that the error is not solved.
The same problems, I described above,
"Unrecognized BLOB ID in...".

I still use temporary solution based on replacing php\ext\php_interbase.dll from php 5.2.1 version.

I don't know which snapshot you tried, but I'm afraid you were testing previous snap, no the NEXT one.
Please try the snap again.
 [2007-08-03 22:49 UTC] idvis at seznam dot cz 
OK,

I downloaded snapshot today again,
then I tested it, and it seems 
the problem IS SOLVED and working with BLOB fields
is now OK again.

Thank you very much for your fix.
When we can expect new PHP release including this fix?
 [2007-08-06 12:55 UTC] tony2001@php.net 
The very next release will incorporate this change.
