Calling a function from a $var

[led_belly]

Some basic code before I ask my question:

/**
* Associates all class variable names to the function name that sets it.
*
* Format: array(name of variable => function that creates it)
*/
function _ws_var_to_method_assoc() {

    return
    $this->var_assoc = array(
                             'uri_req_array' => 'func_req_array',
                             'uri_ss_array' => 'func_ss_array',
                             'uri_sliced_req_array' => 'func_sliced_req_array'
                            );

}


function _ws_var_set($var) {

    $assoc = $this->_ws_var_to_method_assoc();

    // some code that will set $var by calling the function that is associated to it in $assoc

}

Basically, I want ws_var_set() to attempt to set a variable by calling a function whose name is provided in the $assoc array that is returned by calling the ws_var_to_method_assoc() class method (see comments). Would something like eval() work?

My final objective is to be able to easily satisfy criteria in other methods.

Try this simple example; I think it's what you want:

<?
function f() {
  print "Hello, world!";
}

$a = 'f';
$a();  // notice the output of this
?>
