php class scope issue [duplicate]

Question

I'm having the following issue: I am creating a visual calendar in php with the following code

<?php
class Calendar{

    public $numberOfDays;

    function _construct(){
        $this->$numberOfDays =  cal_days_in_month(CAL_GREGORIAN, date("m"), date("Y"));
    } 

public function drawCalendar(){ 

    echo '<div class="month">';
    for( $i=0; $i< $numberOfDays;$i++){     
        echo '<div class="day"></div>';
    }
    echo '</div>';

   }
}
?>

The problem is somehow $numberOfDays is not available in the for loop ? And I am getting a Undefined variable: numberOfDays error. What am I doing wrong

For one thing you forgot an underscore in _construct() change it to __construct() - Constructs require 2 underscores. — Funk Forty Niner

thanks all I also forgot that for object references you have to use the $ only for this and not for the to be accessed variable also (bit hard getting back on php after C# :) ) — timwashere

You need to use:

$this->numberOfDays

$this being a reference to the current object instance
