getting the string to read as php zend statement

Hi I' using zend as my framework, which i've got a problem, what i want to do is ill get the crit base on the get_param then the id is the modelname which i'll append to this command " new Model_Select_.'$table'.(); " as all of my models have the same ane format ony changing their tablename

. but it'll give me the error "Parse error: syntax error, unexpected ')" can anyone help me through this?

    $table = $this->_getParam('crit');
    $curr_model = new Model_Select_.'$table'.(); //it will not accept this 
    $this->view->table = $curr_model->fetchAll();  

PHP:

i tried storing the statement as

$string = " new Model_Select_.'$table'.();";
$curr_model = $string;

PHP:

but the result is the statement was read as a string instead of processing the action, i tried the eval() code but its not working

$curr_model = eval("new Model_Select_".$table."();");

Code (markup):

thanks

 

$table = $this->_getParam('crit');    

[B]$string = " \$curr_model = new Model_Select_{$table}();";[/B]
eval($string);

$this->view->table = $curr_model->fetchAll();
