information that was originally requested, please do so and change
the status of the bug back to "Open".

The problem is still there in 5.2.3, please reopen this bug.

Tested on linux 64bit.

Configure:


./configure  --with-interbase=/opt/firebird --with-config-file-path=/etc \
 --with-apxs2=/usr/sbin/apxs2 \
 --with-gd=/usr/lib64 \
 --includedir=/usr/include \
 --enable-fastcgi \

 --with-mysql=/usr/local/lib/mysql/ \
 --with-openssl_dir=/usr/include/openssl \
 --with-curl \
 --with-curlwrappers \
 --with-zlib \
 --without-pear

This bug really persists in 64 bit linux.
(on Linux-32 works)

I'm having these problems too on Windows XP (32bit) with Firebird 2.1. When I tried to use php_interbase.dll from version 5.2.1 everything works fine. 5.2.3 & 5.2.6 are not working.

slove this problem,php,please!

Dont know where to post the solution. Thats i'll try this way.

Solution: 
- get the sources of your php-version
- in ext/interbase/ibase_blobs.c search the function 
"_php_ibase_quad_to_string"
- replace the line "spprintf(&result, BLOB_ID_LEN+1, "0x%0*" LL_MASK 
"x", 16, *(ISC_UINT64*)(void *) &qd);" with "spprintf(&result, 
BLOB_ID_LEN+1, "0x%0*x%0*x", 8, qd.gds_quad_low, 8, 
qd.gds_quad_high);"
- compile the interbase module (./configure --with-
interbase=shared,/opt/firebird)
- copy the module (modules/interbase.so) to /usr/lib64/php/modules
- try it ... should work

This worked for me.
My System: Fedora Core 8 64bit, php 5.2.6, Firebird 2.1
