#32790 [NEW]: Overloading builtin functions

From: timo dot hummel at 4fb dot de Operating system: n/a PHP version: 5.0.4 PHP Bug Type: Feature/Change Request Bug description: Overloading builtin functions Description: ------------ A very helpful and nice feature for PHP would be to overload builtin functions. As PHP5 now features the functions echo and print are calling the method __toString if it exists in a class, that feature is still lacking in many other functions where they may be useful (like sprintf, printf, just to name a few). To prevent that PHP developers have to do alot of work and to provide a general interface, something like the following pseudo code demonstrates overloading builtin functions: <?php function myOwnEcho () { $ts = date("Y-m-d H:i:s"); print ($ts . " "); $num_args = func_num_args(); for ($i=0; $i < $num_args; $i++) { print (func_get_arg($i)); } } overload_function("echo", "myOwnEcho"); echo "foo"; ?> Results in: 2004-04-21 15:09:01 foo I know that echo is a language construct and not a function, it's just been used because most PHP developers use echo for output. -- Edit bug report at http://bugs.php.net/?id=32790&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32790&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32790&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32790&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32790&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32790&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32790&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32790&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32790&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32790&r=support Expected behavior: http://bugs.php.net/fix.php?id=32790&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32790&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32790&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32790&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32790&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32790&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32790&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32790&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32790&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32790&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32790&r=mysqlcfg
