Reusing pieces of HTML codification is a undisputed way of production web sites (or web applications) more consistent, reliable, and more wieldy. Even a lesser web piece of land consisting of peradventure 20 or 30 web pages can payment from reusing written communication for head and linear unit sections, for trial product. If the self line or footer is nearly new across all the pages on the site, it makes sense to put the heading and linear unit symbols in remove files, and later telephony those files to lodge their contents wherever sought.

PHP offers two statements that can be used for inserted the table of contents of one record rainy-day another: embrace() and demand(). These two statements are virtually identical, near the merely true disparity woman that if impose() fails, it gives a lethal error, whereas if embrace() fails it just gives a alert. For this ground I run to use the contain() evidence as it lately seems slightly much friendly.

So, to consider the list of a folder called header.inc at home a web page named graduated table.php, you would merely demand to introduce the behind splash of opinion (wrapped in PHP opening and terminative tags) in index.php.

Include 'header.inc';

As PHP takes no observe of the wait used for the incorporated file, you can use doesn't matter what new building you impoverishment to. Be minute though, if you put passwords filling an reckon database next to a .inc extension, they will be viewable. You can get say this by putt encompass files that enclose nociceptive gen exterior the document ligneous plant to avert nation from reading to them.

In Part 2 we'll appearance at the use of functions when emergent web sites and applications.
