PHP 5.4

如何在php中调用constructure中的函数？它可能看起来像一个变量函数或指针函数。以下代码在function $EmailAddress处获得sytax错误。如何纠正：

    function __construct($username,$password,$EmailAddress,$mailserver='localhost',$servertype='imap',$port='143',$ssl = true) { 
        if($servertype=='imap') { 
            if($port=='') 
                $port='143'; 
            $strConnect='{'.$mailserver.':'.$port.'/imap/ssl/novalidate-cert}'; 
        } else { 
            $strConnect='{'.$mailserver.':'.$port. '/pop3'.($ssl ? "/ssl" : "").'}INBOX'; 
        } 
        //echo $port;
        $this->server = $strConnect;
        $this->username = $username;
        $this->password = $password;
        $this->email = $EmailAddress;
    } 
    //Connect To the Mail Box
    function $EmailAddress { 
        $this->marubox=@imap_open($this->server,$this->username,$this->password); 

        if(!$this->marubox) { 
            echo "Error: Connecting to mail server"; exit; 
        }
    }

修改

也不起作用。

        $this->email = "EmailAddress";
    } 
    //Connect To the Mail Box
    function EmailAddress() { 
        $this->marubox=@imap_open($this->server,$this->username,$this->password); 

        if(!$this->marubox) { 
            echo "Error: Connecting to mail server"; exit; 
        }
    }

Answer 1

您的代码中存在逻辑错误。您必须更改该函数的名称并按此调用它。

function __construct($username,$password,$EmailAddress,$mailserver='localhost',$servertype='imap',$port='143',$ssl = true) { 
    if($servertype=='imap') { 
        if($port=='') 
            $port='143'; 
        $strConnect='{'.$mailserver.':'.$port.'/imap/ssl/novalidate-cert}'; 
    } else { 
        $strConnect='{'.$mailserver.':'.$port. '/pop3'.($ssl ? "/ssl" : "").'}INBOX'; 
    } 
    //echo $port;
    $this->server = $strConnect;
    $this->username = $username;
    $this->password = $password;
    $this->email = $EmailAddress;

    // Call a function like this.
    $this->setupEmail();
} 
//Connect To the Mail Box
private function setupEmail() { 
    $this->marubox=@imap_open($this->server,$this->username,$this->password); 

    if(!$this->marubox) { 
        echo "Error: Connecting to mail server"; exit; 
    }
}

尝试，

function __construct($username,$password,$EmailAddress,$mailserver='localhost',$servertype='imap',$port='143',$ssl = true) { 
        if($servertype=='imap') { 
            if($port=='') 
                $port='143'; 
            $strConnect='{'.$mailserver.':'.$port.'/imap/ssl/novalidate-cert}'; 
        } else { 
            $strConnect='{'.$mailserver.':'.$port. '/pop3'.($ssl ? "/ssl" : "").'}INBOX'; 
        } 
        //echo $port;
        $this->server = $strConnect;
        $this->username = $username;
        $this->password = $password;
        $this->email = $EmailAddress;
        $this->connect_imap(); // call the connect method
    } 
    //Connect To the Mail Box
    function connect_imap() { 
        $this->marubox=@imap_open($this->server,$this->username,$this->password); 

        if(!$this->marubox) { 
            echo "Error: Connecting to mail server"; exit; 
        }
    }

如果要动态调用该函数，请尝试

class test{
   private $func;
   public function __construct($functionName){
       $this->func = $functionName;
       $this->{$this->func}();      
   }

   public function my_func(){
         echo "Hello World";
   }

}

$r = new test('my_func');
