This is a widget plugin that allow’s you to mix PHP and html code with mobile 
support. Two text area’s are provided. The first is the standard “Title”. 
The one named “Code:” can mix PHP and html. Two checkboxes allow you to choose 
before and/or after posts. No limit on the number of widgets.
WordPress version 3.4 and higher has defined a function called wp_is_mobile(). 
This can be used inside your code mix to perform certain actions if the 
browser is mobile. Mobile support is via wp_is_mobile() function which returns 
true if on a mobile browser. See the WordPress API for more information.
Dynamic title support means that you can name your widget using the title 
field and not have it displayed in the output. This is useful to give 
your widgets meaningful names so you don’t lose track of what is going 
on with your widgets.
Two variables have been defined for use with Google Mobile Adsense:
$myMobileAdsenseCode; 
$myMobileAdsenseSlot;
This widget requires some knowledge of PHP and HTML coding. Misuse could crash 
your site or cause errors with Adsense.
Examples:
Output: 
5
To use Google mobile adsense include the following in the “Code:” area:
The plugin will take care of the rest. Another check is made to ensure 
that wp_is_mobile is true inside the plugin and that the Google Adsense variable 
has a value.
You can combine both regular and mobile adsense. Be careful.
The following snippet will either show mobile or regular ads depending on the 
browswer used by the end-user.
< ?php 
if ( !wp_is_mobile() ) { 
echo ' 

(adsbygoogle = window.adsbygoogle || []).push({}); 
‘;} 
else { 
$myMobileAdsenseClient=’ca-mb-pub-xxxxxxxxxxxx’; 
$myMobileAdsenseSlot=’xxxxxxxxxx’; 
}?>
