note 76734 added to function.echo

<? function yrsolder ($person=0) { $george = 29; $bobby = 27; if($person==0) // george {$yrs = ($george-$bobby);} if($person==1) // bobby {$yrs = ($bobby-$george);} } echo "I am ".yrsolder(1)." years older than Bobby!"; ?> Will output: 3I am older than Bobby! instead of I am 3 years older than Bobby! This is because php will call functions when they are referenced, before an echo statement is called. So if you have an echo statement inside the function, that echo statement is called first, then the echo statement that originally called the function. ---- Server IP: 69.147.83.197 Probable Submitter: 76.187.6.89 ---- Manual Page -- http://www.php.net/manual/en/function.echo.php Edit -- https://master.php.net/note/edit/76734 Del: integrated -- https://master.php.net/note/delete/76734/integrated Del: useless -- https://master.php.net/note/delete/76734/useless Del: bad code -- https://master.php.net/note/delete/76734/bad+code Del: spam -- https://master.php.net/note/delete/76734/spam Del: non-english -- https://master.php.net/note/delete/76734/non-english Del: in docs -- https://master.php.net/note/delete/76734/in+docs Del: other reasons-- https://master.php.net/note/delete/76734 Reject -- https://master.php.net/note/reject/76734 Search -- https://master.php.net/manage/user-notes.php
