From: benjamin dot morel at strictcoding dot co dot uk Operating system: CentOS 6.3, Windows 7 PHP version: 5.4.5 Package: Reflection related Bug Type: Bug Bug description:ReflectionParameter::isDefaultValueAvailable() wrong result
Description: ------------ When ReflectionParameter::isOptional() returns false, because other parameters after it are required, isDefaultValueAvailable() always return false, even is there actually is a default value. I've read this older bug report: https://bugs.php.net/bug.php?id=41382 It looks like at that time, this behaviour had been considerer consistent. I do think this should be revisited however, as in the example function below, there is absolutely no way with Reflection to get the default value for the given parameter. Reflection is a powerful tool for autowiring in Dependency Injection containers, where it is interesting to check whether default parameters are available, regardless of their order. Test script: --------------- function test(PDO $a = null, $b = 0, array $c) {} $r = new ReflectionFunction('test'); foreach ($r->getParameters() as $p) { echo $p->getName(); echo " isDefaultValueAvailable: " . var_export($p->isDefaultValueAvailable(), true) . "\n"; echo " isOptional: " . var_export($p->isOptional(), true) . "\n"; echo " allowsNull: " . var_export($p->allowsNull(), true) . "\n"; echo "\n"; } Expected result: ---------------- a isDefaultValueAvailable: true isOptional: false allowsNull: true b isDefaultValueAvailable: true isOptional: false allowsNull: true c isDefaultValueAvailable: false isOptional: false allowsNull: false Actual result: -------------- a isDefaultValueAvailable: false isOptional: false allowsNull: true b isDefaultValueAvailable: false isOptional: false allowsNull: true c isDefaultValueAvailable: false isOptional: false allowsNull: false -- Edit bug report at https://bugs.php.net/bug.php?id=62715&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=62715&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=62715&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=62715&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=62715&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=62715&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=62715&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=62715&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=62715&r=needscript Try newer version: https://bugs.php.net/fix.php?id=62715&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=62715&r=support Expected behavior: https://bugs.php.net/fix.php?id=62715&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=62715&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=62715&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=62715&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=62715&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=62715&r=dst IIS Stability: https://bugs.php.net/fix.php?id=62715&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=62715&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=62715&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=62715&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=62715&r=mysqlcfg
