Doc #77878 [NEW]: array_filter example improvement

From: php-bugs at allenjb dot me dot uk Operating system: PHP version: Irrelevant Package: Documentation problem Bug Type: Documentation Problem Bug description:array_filter example improvement Description: ------------ The 2nd example for array_filter shows its usage without a callback to filter empty array elements. The example does not include entries for zero values, which could cause issues for newer developers who aren't familiar with PHP's type system. I would suggest updating the example to include zero values: $entry = array( 0 => 'foo', 1 => false, 2 => -1, 3 => null, 4 => '', 5 => '0', 6 => 0, ); print_r(array_filter($entry)); -- Edit bug report at https://bugs.php.net/bug.php?id=77878&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=77878&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=77878&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=77878&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=77878&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=77878&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=77878&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=77878&r=needscript Try newer version: https://bugs.php.net/fix.php?id=77878&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=77878&r=support Expected behavior: https://bugs.php.net/fix.php?id=77878&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=77878&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=77878&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=77878&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=77878&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=77878&r=dst IIS Stability: https://bugs.php.net/fix.php?id=77878&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=77878&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=77878&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=77878&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=77878&r=mysqlcfg
