HTML 特殊文字への変換


  shift_jis




shift_jis では、半角カナの変換に失敗するので、mb_convert_encoding で euc-jp に変換
してから処理し、再度 shift_jis へ戻しています

  

<?
header( "Content-Type: text/html; Charset=shift_jis" );
header( "Expires: Wed, 31 May 2000 14:59:58 GMT" );

foreach( $_GET as $Key => $Value ) {
	$_POST[$Key] = $_GET[$Key];
}
foreach( $_POST as $Key => $Value ) {
	$_POST[$Key] = str_replace("\\\\", "\\", $Value );
	$_POST[$Key] = str_replace("\\'", "'", $_POST[$Key] );
	$_POST[$Key] = str_replace("\\\"", "\"", $_POST[$Key] );
}
$Text = mb_convert_encoding( $_POST['text'], "euc-jp", "shift_jis" );
$Text = htmlentities( $Text, ENT_NOQUOTES, "euc-jp" );
$Text = htmlentities( $Text, ENT_NOQUOTES, "euc-jp" );
$Text = mb_convert_encoding( $Text, "shift_jis", "euc-jp" );
?>

  入力された文字列の表示

特殊文字の表示テストや、HTML を記述した結果をチェックしたりします。
また、クリップボードへのコピーは、innerHTML を使用して HTML 表現を取得するようにしています。
( このコピーされた文字列は、IE が補完、補正したものが返るので、入力した文字列と同じとは限りません )

  

<?
header( "Content-Type: text/html; Charset=shift_jis" );
header( "Expires: Wed, 31 May 2000 14:59:58 GMT" );

foreach( $_GET as $Key => $Value ) {
	$_POST[$Key] = $_GET[$Key];
}
foreach( $_POST as $Key => $Value ) {
	$_POST[$Key] = str_replace("\\\\", "\\", $Value );
	$_POST[$Key] = str_replace("\\'", "'", $_POST[$Key] );
	$_POST[$Key] = str_replace("\\\"", "\"", $_POST[$Key] );
}
$Text = $_POST['text'];
