Android EditText - hide soft keyboard on focus but keep cursor visible

In my current android app I have a lot of input fields (EditText) and I need to disable the soft keyboard on focus, because I use my own kind of input widget.

I've try several solutions, but on some was the cursor not visible or the soft keyboard was blinking on focus for some ms. But this one works:

    public static void disableSoftKeyboard(final EditText v) {
        if (Build.VERSION.SDK_INT >= 11) {
            v.setRawInputType(InputType.TYPE_CLASS_TEXT);
            v.setTextIsSelectable(true);
        } else {
            v.setRawInputType(InputType.TYPE_NULL);
            v.setFocusable(true);
        }
    }

PHP session timeout cookie lifetime

There are many ways to set cookie based session timeout in PHP. You can edit your php.ini or put it in .htaccess but I choose for today this piece of code:

<?php
ini_set('session.gc_maxlifetime', 172800);
ini_set('session.cookie_lifetime', 172800);
session_start();
?>

The session above will be valid for 2 days.
