CFML file extension

The cfml file extension is associated with web pages written in the ColdFusion Markup Language (CFML), a tag-based language similar to HTML, that uses special tags and functions.

With CFML, you can enhance standard HTML files with database commands, conditional operators, high-level formatting functions, and other elements to rapidly produce easy-to-maintain web applications. However, CFML is not limited to enhancing HTML. For example, you can create Macromedia Flash MX applications that consist entirely of Flash elements and CFML. Similarly, you can use CFML to create web services for use by other applications.

ColdFusion Markup Language (CFML) is ColdFusions own set of tags that makes up the bulk of the dynamic functionality found on ColdFusion pages. CFML has two different parts that make ColdFusion work: tags and functions.

Tags are used to carry out operations, such as looping over Recordsets, uploading files to a web server by way of a web form, dumping the contents of a variable to the screen for debugging, and grabbing the contents of a remote page on the Web. Functions within ColdFusion are used to manipulate data or perform calculations. For example, ColdFusion has a function called #ArrayAvg()#, which calculates the average of the numeric values within an array. You often must use tags and functions together to build a completely functional site.
