From: Operating system: PHP version: Irrelevant Package: Arrays related Bug Type: Feature/Change Request Bug description:Implement array_first() and array_last()
Description: ------------ Retrieving the first or the last element of an array (without modifying the array) is a very common task. It is really annoying that PHP wouldn't come with built-in functions to do that. Can you please implement the following 2 array functions: array_first(array $array) - returns the first element of $array array_last(array $array) - returns the last element of $array Also consider implementing another pair of function to retrieve the keys: array_first_key and array_last_key. Test script: --------------- $test = array( 100 => "a", 200 => "b", 300 => "c", 400 => "d"); echo array_first($test)."\n"; echo array_last($test)."\n"; echo key($test)."\n"; echo implode(",", $test); Expected result: ---------------- a d 100 a,b,c,d Actual result: -------------- Fatal error: Call to undefined function array_first() on line 3 -- Edit bug report at https://bugs.php.net/bug.php?id=61946&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=61946&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=61946&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=61946&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=61946&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=61946&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=61946&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=61946&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=61946&r=needscript Try newer version: https://bugs.php.net/fix.php?id=61946&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=61946&r=support Expected behavior: https://bugs.php.net/fix.php?id=61946&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=61946&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=61946&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=61946&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=61946&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=61946&r=dst IIS Stability: https://bugs.php.net/fix.php?id=61946&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=61946&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=61946&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=61946&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=61946&r=mysqlcfg
