#47903 [NEW]: Precision about "@" operator

From: cFreed at orange dot fr Operating system: Win XP PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: Precision about "@" operator Description: ------------ A case where the error-control operator @ does NOT work, despite of what the manual says. Reproduce code: --------------- --- From manual page: language.operators.errorcontrol --- The manual says: "A simple rule of thumb is: if you can take the value of something, you can prepend the @ operator to it." This is not always true. As shown by the example given, this works, assuming $cache IS AN ARRAY: <?php $value = @$cache[$key]; // will not issue a notice if the index $key doesn't exist. ?> But it does not work if $cache IS A STRING, and $key is an integer higher than strlen($cache)-1. in other words: <?php $str='abc'; $value=@$str[5]; // will issue the notice "Uninitialized string offset 5 in...". ?> -- Edit bug report at http://bugs.php.net/?id=47903&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47903&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47903&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47903&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47903&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47903&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47903&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47903&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47903&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47903&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47903&r=support Expected behavior: http://bugs.php.net/fix.php?id=47903&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47903&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47903&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47903&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47903&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47903&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47903&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47903&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47903&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47903&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47903&r=mysqlcfg
