Bug #17654: array_merge() throws warning when supplied with 1 argument only

From: carlos@wfmh.org.pl Operating system: Linux GNU/Debian PHP version: 4.2.1 PHP Bug Type: Arrays related Bug description: array_merge() throws warning when supplied with 1 argument only array_merge() throws an "Wrong parameter count" if called with only 1 argument given. I consider it a bug, as there's no technical reason it should act that way. One can say merging one array makes no sense, which is correct from logical point of view, but from the ther side, technical, there's nothing that I can imagine to prevent array_merge() to handle this case w/o any error. Currently if I write a code that utilises array_merge() and I plan it to scale later on, I can 't simply write $res = array_merge( $arr1 ); and expand the lists later on, if I get more arrays. -- Edit bug report at http://bugs.php.net/?id=17654&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=17654&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=17654&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=17654&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=17654&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=17654&r=support Expected behavior: http://bugs.php.net/fix.php?id=17654&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=17654&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=17654&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=17654&r=globals
