今日作ったツール： mailtoとかで使うurlencode文字列取得

php 
<?php
/*
 * FileName: urlencode.php
 * Desc.   : 与えられた文字列を、URLエンコードして返す。
 *
*/
ini_set("register_globals",              "Off");
ini_set("track_vars",                    "On");
ini_set("output_buffering",              "Off");
ini_set("mbstring.language",             "Japanese");
ini_set("mbstring.internal_encoding",    "EUC-JP" );
ini_set("mbstring.http_input" ,          "SJIS-win,EUC-JP,UTF-8,JIS");
ini_set("mbstring.http_output",          "SJIS" );
ini_set("mbstring.detect_order",         "SJIS-win,EUC-JP,UTF-8,JIS" );
ini_set("mbstring.encoding_translation", "On");
