色々あって、Smartyが使えないケースがありまして、
しかし！私の気持ちてきにはsmartyを使って画面表示制御を行ないたくて…

出した結論が…

Smartyっぽいクラスで代替しよう！でした。
まぁ、そんな時に書いたのが下記のクラスです。

class MySmarty {
	protected $template_dir;
	protected $assign;
	protected $disp_stream;
	protected $const;

	public function __construct(){
		$this->template_dir	= PRIVATE_DIR.'display';
		$this->assign = array();
		$this->const['BASE_URL'] = BASE_URL;
	}

	public function assign( $arg1, $arg2 = null){
		if( is_array( $arg1) ){
			if( count($arg1) == 0 ) return;
			foreach( $arg1 as $i => $v ) $this->assign[$i] = $v;
		} else {
			$this->assign[$arg1] = $arg2;
		}
	}

	public function setConstants( $arg1, $arg2 = null){
		if( is_array( $arg1) ){
			if( count($arg1) == 0 ) return;
			foreach( $arg1 as $i => $v ) $this->const[$i] = $v;
		} else {
			$this->const[$arg1] = $arg2;
		}
	}

	public function setDisplay( $file ){
		$file = $this->template_dir.'/'.$file;
		$this->disp_stream = file_get_contents( $file );
	}

	public function display(){
		$disp = $this->disp_stream;

		$this->assign( $this->const );
		foreach( $this->assign as $i => $v ){
			$disp = str_replace( '{'.$i.'}', $v, $disp );
		}
		$disp = str_replace( '{literal}', '', $disp );
		$disp = str_replace( '{/literal}', '', $disp );

		echo $disp;
	}

	public function getIndexs(){
		$str = $this->disp_stream;
		$ret = array();
		$max = strlen( $str );
		$pos = 0;
		$qti = '';
		while( ($pos = strpos( $str, '{', $pos )) !== false ) {
			$epos = 0;
			if( ($epos = strpos( $str, '}', $pos )) === false ){
				echo "'}' is not found";
				break;
			}
			$tmp = substr( $str, $pos+1, $epos - $pos -1 );
			switch( $tmp ){
				case 'literal':
					$pos = strpos( $str, '{/literal}' );
					if( $pos === false ) die('literal format error');
					$pos += 10;
					continue;

				case 'qtiBegin':
					$dpos = $pos + 10;
					$epos = strpos( $str, '{qtiEnd}', $pos );
					$ret[$qti] = substr( $str, $dpos, $epos - $dpos );
					$tstr = $str;
					$str = substr( $tstr, 0, $pos ).
						substr($tstr, $epos+8);
					$pos = $epos + 8;
					$this->disp_stream = $str;
					continue;
			}
			$ret[$tmp] = '';
			$qti = $tmp;
			$pos = $epos;
		}
		return $ret;
	}
}
