note 106274 added to function.count

simple random value from array. <?php $topic=array( "UFOs", "Barack Obama", "China", "Christianity", "Communism", "World War II", "Global Warming", "Vegetarianism", ); echo ("What do you think about ".$topic[ rand( 1,count($topic) ) ]."? "); ?> output--> What do you think about Global Warming? , etc It worked fine until this output also, randomly pops up: Notice: Undefined offset: 8 in line 100 The line 100 is: echo ("What do you think about ".$topic[ rand( 1,count($topic) ) ]."? "); I removed the count( $topic ) instead and replace it with this: echo ("What do you think about ".$topic[ rand( 0,7 ) ]."? "); and i have not encountered any error notice since. adriandotphp@gmail.com I'm to new to php. ---- Server IP: 69.147.83.197 Probable Submitter: 112.206.106.173 ---- Manual Page -- http://www.php.net/manual/en/function.count.php Edit -- https://master.php.net/note/edit/106274 Del: integrated -- https://master.php.net/note/delete/106274/integrated Del: useless -- https://master.php.net/note/delete/106274/useless Del: bad code -- https://master.php.net/note/delete/106274/bad+code Del: spam -- https://master.php.net/note/delete/106274/spam Del: non-english -- https://master.php.net/note/delete/106274/non-english Del: in docs -- https://master.php.net/note/delete/106274/in+docs Del: other reasons-- https://master.php.net/note/delete/106274 Reject -- https://master.php.net/note/reject/106274 Search -- https://master.php.net/manage/user-notes.php
