示例1: before
public function before(PHPTAL_Php_CodeWriter $codewriter)
{
$this->var = $codewriter->createTempVariable();
// alias to repeats handler to avoid calling extra getters on each variable access
$codewriter->doSetVar($this->var, '$ctx->repeat');
list($varName, $expression) = $this->parseSetExpression($this->expression);
$code = $codewriter->evaluateExpression($expression);
// instantiate controller using expression
