#45628 [NEW]: set_error_handler() return type wrongly documented

From: sebastian@php.net Operating system: Irrelevant PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: set_error_handler() return type wrongly documented Description: ------------ The documentation for set_error_handler() seems to be wrong: <?php function handler($errno, $errstr, $errfile, $errline, $errcontext) {} var_dump(set_error_handler('handler')); var_dump(set_error_handler('handler')); NULL string(7) "handler" So NULL is not used for errors. NULL means the default error handler here apparently. Whereas the documentation reads: "Returns a string containing the previously defined error handler (if any), or NULL on error. If the previous handler was a class method, this function will return an indexed array with the class and the method name." The code reads: "Returns the previously defined error handler, or false on error." -- Edit bug report at http://bugs.php.net/?id=45628&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=45628&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=45628&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=45628&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=45628&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=45628&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=45628&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=45628&r=needscript Try newer version: http://bugs.php.net/fix.php?id=45628&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=45628&r=support Expected behavior: http://bugs.php.net/fix.php?id=45628&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=45628&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=45628&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=45628&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=45628&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=45628&r=dst IIS Stability: http://bugs.php.net/fix.php?id=45628&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=45628&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=45628&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=45628&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=45628&r=mysqlcfg
