openssl拡張でimaps

      ぢょ〜@よくきたなです．

      PHP が SSL stream に対応していたら POP3 over SSL はできます．

    下記簡易的に書きます．
$ php -r '

  require_once "Net/POP3.php";

  $obj = new Net_POP3;

  var_dump( $obj->connect( "ssl://mail.example.com", 995));

  var_dump( $obj->login( "user", "password"));

  var_dump( $obj->numMsg());'

bool(true)

bool(true)

int(501)

popsができるんならimapsということでやってみた。環境は--with-openssl付きでbuildしたPHP5.1.4。

<pre>
<?php
$sock = fsockopen("tls://imaps-server", 993, $errno, $errstr, 15);
echo fread($sock,1024);

$seq = 1;
fwrite($sock, $seq++ . " capability\r\n");
echo fread($sock,1024);
fwrite($sock, $seq++ . " LOGIN user password\r\n");
echo fread($sock,1024);
fwrite($sock, $seq++ . " namespace\r\n");
echo fread($sock,1024);
fwrite($sock, $seq++ . " examine inbox\r\n");
echo fread($sock,1024);
fwrite($sock, $seq++ . " logout\r\n");
echo fread($sock,1024);
?>
</pre>

な感じで、結果は

となった。まあ、openssl使ってIMAPコマンド叩いてるのと同じだわな。
