PHP Modification of a Script

Shouldn't take longer than an hour for an experienced coder! <?php if(intval($_GET['part']) ==1) { echo $videodata['code1']; } elseif(intval($_GET['part']) ==2 and $videodata['code2']!='') { echo $videodata['code2']; } elseif(intval($_GET['part']) ==3 and $videodata['code3']!='') { echo $videodata['code3']; } elseif(intval($_GET['part']) ==4 and $videodata['code4']!='') { echo $videodata['code4']; } elseif(intval($_GET['part']) ==5 and $videodata['code5']!='') { echo $videodata['code5']; } else { echo $videodata['code1']; } ?> What I essentially need is that for each ['codeX]' it is echoed with an additional code, depending on an additional value which is also fetched using $videodata: echo $videodata['code1']; To be specific, I would like that the code first checks if: $videodata['videotype1'] = 'YouTube'. If 'videotype1' is indeed 'YouTube' then it should: echo $videodata."<iframe width="420" height="345" src="[login to view URL]".['code1']."></iframe>"; But if 'videotype1' is not 'YouTube', but instead it is Vimeo then it should: echo $videodata."<iframe src="[login to view URL] video/".['code1']."width="500" height="281" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen> </iframe>"; This should also be the case for code2, code3, etc..! What is the best way to do it and can you do it?
