我的PHP脚本有什么问题？ [关闭]

Question

I want this php script to first decide whether or not it should send the following emails, all using data received from a form in another html file. At the moment I'm really not sure what I'm doing with php nor do I know where to start. For the sake of the task, I want the person to correctly identify the picture and match it with pre-assigned passwords. Once they have done this correctly 2 emails would be sent. How would I go about formatting this?

I've adjusted my code with Ian and ThomasEliss' help (Thank you for your insight), however, when I click submit on my form, it simply takes me to the php file, displaying a blank screen. What am I doing wrong. Thank you for your help :)

You could change the following

$password1 = '2Vd27VFfkK' ;
$password2 = 'MjgxfNA5Qn' ;
$password3 = 'tg3K3GhS6W' ;
$password4 = 'n2m6GHfVSK' ;
$password5 = 'RTxqN5euFX' ;
$password6 = 'AJzsWwES6D' ;
$password7 = '24hAgsHuW3' ;
$password8 = 'xHzvW9kyFk' ;
$password9 = 'CyXH7VRhyp' ;
$password10 = 'QshfjUn75Z' ;

if $usrpassword == $password1 || $usrpassword == $password2 || $usrpassword == $password3 || $usrpassword == $password4 || $usrpassword == $password5 || $usrpassword == $password6 ||$usrpassword == $password7 || $usrpassword == $password8 || $usrpassword == $password9 || $usrpassword == $password10

To

$passwords = array();
$passwords[] = '2Vd27VFfkK' ;
$passwords[] = 'MjgxfNA5Qn' ;
$passwords[] = 'tg3K3GhS6W' ;
$passwords[] = 'n2m6GHfVSK' ;
$passwords[] = 'RTxqN5euFX' ;
$passwords[] = 'AJzsWwES6D' ;
$passwords[] = '24hAgsHuW3' ;
$passwords[] = 'xHzvW9kyFk' ;
$passwords[] = 'CyXH7VRhyp' ;
$passwords[] = 'QshfjUn75Z' ;

if(in_array($usrpassword, $passwords))
