Indeed, when including files, they always need to be read (increasing file I/O) and parsed (increasing CPU/memory). So it would be better to only include files whenever you need them.<br />
<br />
On the other hand, files that are used very often are very efficiently handled by your OS. And when you use something like ZEND optimizer, the parsed files are stored. The impact would then be quite little.<br />
<br />
Also, when you are not encountering any problems with your request-load (i.e. the impact on the server with a single call to a page) then you don't need to bother with optimizing this (unless you expect it to be a problem in the future of course).

Dear all,<br />
<br />
when i write this these pages i use include files for to increase flexibility. i &nbsp;would like to if this increase load of the page, since this inc page would include lot of utilities, constants and so on....<br />
rather than giving every thing in a single file is wise to break up those in to secitons and include as separate files.<br />

php includes

Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services using a wide variety of languages and standards, including the familiar HTML, JavaScript and jQuery, ASP and ASP.NET, PHP, ColdFusion, CSS, PHP, Flex and Flash, but also the implementation of a broad list of standards including XML, WSDL, SSDL, VoiceXML and many more.

Web Languages and Standards

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.
