#32986 [NEW]: The documentation for exif_read_data() doesn't say if it validates tags

From: avarab at gmail dot com Operating system: GNU/Linux PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: The documentation for exif_read_data() doesn't say if it validates tags Description: ------------ The documentation for exif_read_data() at http://www.php.net/exif_read_data doesn't state whether or not the function validates Exif data before returning it, my guess is not but it should be explicitly stated. Validation of Exif data would be to check if the contents of a given tag conform to the value it's supposed to hold according to the Exif specification ( see: http://exif.org/Exif2-2.PDF , page 20), for example a tag which should hold a BYTE (according to the spec) should not hold anything besides an 8bit integer, short should not be anything besides a 16 bit unsigned integer and so on. I'm not suggesting that exif_read_data() does this (if it doesn't) but merely that the documentation be updated to state whether or not it does. -- Edit bug report at http://bugs.php.net/?id=32986&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32986&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32986&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32986&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32986&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32986&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32986&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32986&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32986&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32986&r=support Expected behavior: http://bugs.php.net/fix.php?id=32986&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32986&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32986&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32986&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32986&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32986&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32986&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32986&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32986&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32986&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32986&r=mysqlcfg
