Bug #79865 [NEW]: Requiring a file twice with `require` doesn't reload anonymous classes

From: d28b312d at opayq dot com Operating system: N/A PHP version: Irrelevant Package: *Compile Issues Bug Type: Bug Bug description:Requiring a file twice with require doesn't reload anonymous classes Description: ------------ Requiring a file twice (using require _not_ require_once), will reload a file and run all the code but won't redefine anonymous classes in that code. The file is loaded and the code to define the object is run, but as the hash is the same it doesn't redefine it. The echo statement above the anonymous class _is_ run both times and is different both times, as expected. There is _no_ warning and _no_ change, but the rest of the code still continues to run. This seems like very unexpected behaviour. This is the vld output gist: https://gist.github.com/ElvenSpellmaker/940fa8b4fd5523a81a42fb9686266d67 From that gist, the first time the class is loaded: ------------------------------------------------------------------------------------- 3 0 E > ECHO 'Title%3A+foo' 1 ECHO '%0A' 5 2 DECLARE_ANON_CLASS 9.88131e-324 3 NEW $1 0 4 DO_FCALL 0 5 > RETURN $1 9 6* > RETURN 1 And the second time: ------------------------------------------------------------------------------------- 3 0 E > ECHO 'Title%3A+bar' 1 ECHO '%0A' 5 2 DECLARE_ANON_CLASS 9.88131e-324 3 NEW $1 0 4 DO_FCALL 0 5 > RETURN $1 9 6* > RETURN 1 As you can see there doesn't appear to be a point where it skips the redefine, but I assume as the hash comes back as '9.88131e-324' both times it doesn't actually declare the class again. Test script: --------------- index.php: <?php $class = require 'test.php'; echo 'Get Name: ' . $class->getName(); # Replace foo with bar to try and test a class reload $foo = file_get_contents('test.php'); $foo = str_replace('foo', 'bar', $foo); file_put_contents('test.php', $foo); echo "\n"; $class2 = require 'test.php'; echo 'Get Name: ' . $class2->getName(); # Reset file $foo = str_replace('bar', 'foo', $foo); file_put_contents('test.php', $foo); --- test.php: <?php echo 'Title: foo', "\n"; return new class { private $name = 'foo'; public function getName() { return $this->name; } }; Expected result: ---------------- Title: foo Get Name: foo Title: bar Get Name: bar Actual result: -------------- Title: foo Get Name: foo Title: bar Get Name: foo -- Edit bug report at https://bugs.php.net/bug.php?id=79865&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=79865&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=79865&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=79865&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=79865&r=needscript Try newer version: https://bugs.php.net/fix.php?id=79865&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=79865&r=support Expected behavior: https://bugs.php.net/fix.php?id=79865&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=79865&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=79865&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=79865&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=79865&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=79865&r=dst IIS Stability: https://bugs.php.net/fix.php?id=79865&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=79865&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=79865&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=79865&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=79865&r=mysqlcfg
