#31095 [NEW]: Nonstatic function can be called as if is static

From: levi at alliancesoftware dot com dot au Operating system: PHP version: 5.0.2 PHP Bug Type: Zend Engine 2 problem Bug description: Nonstatic function can be called as if is static Description: ------------ If you call a member function in another class, it succeeds and $this is set to the *calling* class. The new PHP 5 object model should make the function inaccessible, unless [a] It is a static function ($this should be unset) [b] It is an ancestor class of the calling class ($this should be set) [c] PHP 4 compatibility is on ($this should be set) At the very minimum, this should generate an error in strict mode. This may have been the expected behaviour in PHP 4, but PHP 5 has a static keyword for exactly this situation now. Note: This was reported in PHP4 under bugs #19384 and #12622 and was (incorrectly) claimed to have been fixed in #19194 (it still occurs in 4.3.4) Note: Currently, $this is unset if [a] you call a global (non class) function [b] otherClassMethod() is declared static Reproduce code: --------------- #!/usr/local/bin/php -qC <? error_reporting(E_ALL | E_STRICT); class OtherClass { public function otherClassMethod() { echo "Called otherClassMethod() from within class ". get_class($this)."\n"; } } class NormalClass { public function __construct() { OtherClass::otherClassMethod(); } } new NormalClass(); ?> Expected result: ---------------- PHP Notice: Undefined variable: this in testStatic2.php5 on line 7 (or even better): PHP Notice: Calling nontstatic function as static in testStatic2.php5 on line 14 Actual result: -------------- Called otherClassMethod() from within class NormalClass -- Edit bug report at http://bugs.php.net/?id=31095&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=31095&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=31095&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=31095&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=31095&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=31095&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=31095&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=31095&r=needscript Try newer version: http://bugs.php.net/fix.php?id=31095&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=31095&r=support Expected behavior: http://bugs.php.net/fix.php?id=31095&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=31095&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=31095&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=31095&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=31095&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=31095&r=dst IIS Stability: http://bugs.php.net/fix.php?id=31095&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=31095&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=31095&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=31095&r=mysqlcfg
