PHPに惚れました

今でも多分惚れてます。

PHPで携帯電話からのアクセスかを判別するスクリプト書いた

PHP PEAR

携帯からのみアクセスを許したいページを作りたいとき、何で判別していますか？

UserAgentで判別。それだけではいけません。

UserAgentなんて簡単に偽装されてしまいます。

そこで、IPアドレス帯域を検査することで大丈夫。

携帯電話は各キャリアのサーバを経由してWebサーバにアクセスします。
その際、Webサーバに対して各キャリアのサーバのIPアドレスがリクエスト要求元のIPアドレスとして通知されます。

これは偽装しようが無いので信頼できる情報です。

下準備

2つのPEARパッケージのインストールが必要です。
インストールされてない方はインストールして下さい。

インクルードパスの設定なども各自。

利用方法

<?php
try{
	$mb = new MobileCheck;

	if($mb->Check()===TRUE){
		print "(mobile access)<br>携帯電話からのアクセスですね？";
	}else{
		print "(not mobile access)<br>携帯電話以外からのアクセスですね？";
	}
}catch(Exception $e){
	print $e->getMessage();
}
?>

MobileCheckクラスをインスタンス化して、Checkメソッドを呼び出すだけ。
Checkメソッドを呼び出すと、携帯と判別すればTRUE,携帯ではないと判別すればFalseが返る。

これだけ。

手法

テストした機種

(携帯として判別)

(携帯電話ではないと判別)

イーモバイルは判定対象外みたいですので無条件で携帯以外と判別されました。
スマートフォンも携帯電話ではない判別されました。
