Here is a way to insert php scripts on blogger blogs. It really is awesome.
– Log in to your blogger account, Go to Design >> Page Elements.
– Paste this code.
<object width="400" height="300" type="text/html"data=" Your URL.php "></object>
Now replace URL.php with the URL php file you are hosting somewhere else.
– You can now save and enjoy PHP features on blogger.
