#25763 [NEW]: Why the string "1.10" is equal to the string "1.1"?

From: jparneodo at yahoo dot fr Operating system: RH7.2 PHP version: 4.3.3 PHP Bug Type: Strings related Bug description: Why the string "1.10" is equal to the string "1.1"? Description: ------------ I excepted true if one of the compared variable was numeric, because of type juggling rules (Appendix K. PHP type comparison tables), but false when the 2 variables are string. In this case == and === must have the same result. Reproduce code: --------------- $a=(string)"1.1"; $b=(string)"1.10"; if($a==$b) echo "equal"; else echo "different"; Expected result: ---------------- different Actual result: -------------- equal -- Edit bug report at http://bugs.php.net/?id=25763&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=25763&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=25763&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=25763&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=25763&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=25763&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=25763&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=25763&r=support Expected behavior: http://bugs.php.net/fix.php?id=25763&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=25763&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=25763&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=25763&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=25763&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=25763&r=dst IIS Stability: http://bugs.php.net/fix.php?id=25763&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=25763&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=25763&r=float
