note 60574 added to function.echo

My benchmark was running on Apache/2.0.55 (Unix) PHP/5.1.1: I took 150000 iteration and saved the results in the session for multiple requests. the results are the intersection of quite a lot requests. the benchmark times were constant and show echo 'Key is ', $k, '<br>',"\n",'Value is ', $v, '<br><br>', "\n"; 0.138133585453 echo 'Key is ', $k, "<br>\nValue is ", $v, '<br><br>', "\n"; 0.114041343331 echo "Key is $k<br>\nValue is $v<br><br>\n"; 0.49078194797 echo 'Key is '. $k. '<br>'."\n".'Value is '. $v. '<br><br>'. "\n"; 0.199534930289 It shows that the fastest way to put content is to echo with multiple parameters and as possible no interpolation. ---- Manual Page -- http://www.php.net/manual/en/function.echo.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60574 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60574&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60574&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60574&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60574&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60574&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60574&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60574&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60574&report=yes Search -- http://master.php.net/manage/user-notes.php
