如何动态更改静态限制php？

Question

I set a start date and end date to show a content.

$sdate = 2015-07-20 0:0
$edate = 2015-07-30 0:0

Now in php how to set this?

php

static $module = 0;
if($module < 1) {   
$this->data['module'] = $module++;
}

tpl

<?php echo $module; ?>

output is 0 . Now i want if i set start date and end date and when output 0 ended then auto define next module number 1

Your static attribute should ideally be in a class:

class MyClass {

    public static $module = 0;

}

Then you can use it like so:

if (MyClass::$module < 1) 
{
    $this->data['module'] = MyClass::$module++;
}
