From: tim dot lokot at printsoft dot com Operating system: Win2K Pro PHP version: 4.3.4 PHP Bug Type: Scripting Engine problem Bug description: Comparison fails for int(0) == string
Description: ------------ For some reason I cannot compare the integer zero to a string and get a valid response back. There are two ways that I can see to fix it: 1. Use the === operator 2. Typecast the integer to a string Both of the above solutions work, yet for some reason, the == comparison operator doesn't. Reproduce code: --------------- <?php $item = 0; var_dump ($item); if ($item == 'rubbish') echo 'Equals'; else echo 'Is not equal'; ?> Expected result: ---------------- int(0) Is not equal Actual result: -------------- int(0) Equals -- Edit bug report at http://bugs.php.net/?id=27475&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=27475&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=27475&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=27475&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=27475&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=27475&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=27475&r=needscript Try newer version: http://bugs.php.net/fix.php?id=27475&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=27475&r=support Expected behavior: http://bugs.php.net/fix.php?id=27475&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=27475&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=27475&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=27475&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=27475&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=27475&r=dst IIS Stability: http://bugs.php.net/fix.php?id=27475&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=27475&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=27475&r=float
