#23105 [Opn->Asn]: read_exif_data fails to read entire string

ID: 23105 Updated by: sniper@php.net Reported By: joncu at autodesk dot com -Status: Open +Status: Assigned Bug Type: mbstring related Operating System: XP PHP Version: 4.3.1 -Assigned To: +Assigned To: edink New Comment: Edin, can you add the missing defines.. Previous Comments: ------------------------------------------------------------------------ [2003-04-08 05:19:21] joncu at autodesk dot com I have now been able to debug this to the point of knowing that it is an MBString problem. HAVE_MBSTRING is not defined in the exif project when config.w32.h has it defined. So, EXIF_USE_MBSTRING does not get defined. I tried manually setting EXIF_USE_MBSTRING, but was unable to get it correct - ending with a problem in the Thread storage accessing the mbstring globals. Anyway, someone more familiar with this code can probably find and fix the problem fairly quickly. It just appears that somewhere in the VC6 dsw and dsp files, the HAVE_MBSTRING extension is not getting set correctly. Also - to create a test JPG, I just used the XP file properties dialog to add summary data to the Title, Comments, etc. fields (under summary/advanced). ------------------------------------------------------------------------ [2003-04-07 23:08:01] joncu at autodesk dot com read_exif_data() will only return the first letter of any WINXP Unicode strings. This only happens in a Win32 build of the php_exif.dll. The bug does not occur in a Linux build. I've confirmed this with both my own build and the currently posted php_exif.dll. I am unable to successfully run a debug build in XP, so I have not been able to debug further. The same data will be read fully under the IFD0 tags, but not under the WINXP tags. The following code ... foreach($exif as $key=>$section) { foreach($section as $name=>$val) { echo "$key.$name: $val<br />\n"; } } ... will return the following relevant data ... IFD0.Title: JMC_TITLE IFD0.Comments: JMC_COMMENTS IFD0.Subject: JMC_SUBJECT WINXP.Title: J WINXP.Comments: J WINXP.Subject: J These two sections should be identical, and are with Linux built binaries. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=23105&edit=1
