'File included' : 'File NOT included'; } else { echo 'File does Not exist<br />'; echo (@include($test_path)) ? 'File included' : 'File NOT included'; } Expected result: ---------------- File does exist File included Actual result: -------------- File does NOT exist File included -- Edit bug report at http://bugs.php.net/?id=48548&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48548&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48548&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48548&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48548&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48548&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48548&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48548&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48548&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48548&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48548&r=support Expected behavior: http://bugs.php.net/fix.php?id=48548&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48548&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48548&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48548&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48548&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48548&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48548&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48548&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48548&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48548&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48548&r=mysqlcfg
