Bug #69124 [NEW]: Method name must be a string ... triggered by a string

From: narf at devilix dot net Operating system: Linux PHP version: master-Git-2015-02-26 (Git) Package: Scripting Engine problem Bug Type: Bug Bug description:Method name must be a string ... triggered by a string Description: ------------ $this->{$method}() calls fail with a "Method name must be a string" error, even if $method is a string (and an existing method too). I've encountered this after assigning $method via sscanf(), so it might be a sscanf() issue, but it doesn't look like it ... Test script: --------------- <?php class Foo { public function test() { sscanf('bar', '%s', $method); var_dump($method); $this->{$method}(); } public function bar() {} } $bar = new Foo(); $bar->test(); Expected result: ---------------- string(3) "bar" Actual result: -------------- string(3) "bar" Fatal error: Method name must be a string in %s on line 8 -- Edit bug report at https://bugs.php.net/bug.php?id=69124&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69124&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69124&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69124&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69124&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69124&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69124&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69124&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69124&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69124&r=support Expected behavior: https://bugs.php.net/fix.php?id=69124&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69124&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69124&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69124&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69124&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69124&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69124&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69124&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69124&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69124&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69124&r=mysqlcfg
