Req #52740 [NEW]: var_export unnecessarily refers to classes in a namespace sensitive way

From: Operating system: N/A PHP version: 5.3.3 Package: Class/Object related Bug Type: Feature/Change Request Bug description:var_export unnecessarily refers to classes in a namespace sensitive way Description: ------------ I use var export to generate PHP code fragments as one of it's strength is that it's output is an expression of parseable PHP. However, when var_export refers to classes, it refers to their relative name (from root) instead of their absolute name, making you unable to use the output in namespace context (contexts with a specified namespace). Too illustrate this problem, say we're exporting an instance of the class 'foo\bar\BazClass'. var_export will now return something like: "foo\bar\BazClass::__set_state(...)" If inserted into a file with a beginning declaration "namespace foo_space" this code will not work as the class in the expression would refer to foo_space\foo\bar\BazClass which is incorrect and probably throws a fatal error. A simple fix is to make the ouput of var_export return namespaced classes with an initial '\' e.g. instead of the above, make it return: "\foo\bar\BazClass::__set_state(...)" This would make the expression work in any namespace context. Test script: --------------- <?php namespace foo\bar; class BazClass { public $x = 3.14; public $y = 5.14; } $baz = new BazClass(); $baz->x = 4.14; $baz->y = 5.14; $file = tempnam(sys_get_temp_dir(), "tst"); file_put_contents($file, '<?php namespace foo_space; return ' . var_export($baz, true) . ";"); $class = require($file); echo $class->x + $class->y; Expected result: ---------------- 9.28 Actual result: -------------- Fatal error: Class 'foo_space\foo\bar\BazClass' not found in C:\Windows\Temp\tst88FE.tmp on line 1 -- Edit bug report at http://bugs.php.net/bug.php?id=52740&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52740&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52740&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52740&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52740&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52740&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52740&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52740&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52740&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52740&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52740&r=support Expected behavior: http://bugs.php.net/fix.php?id=52740&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52740&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52740&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52740&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52740&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52740&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52740&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52740&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52740&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52740&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52740&r=mysqlcfg
