Hello,
Expanding on the previous reply:
Along with being a central repository of shared, portable code, the PEAR project lays down ground rules for how to format your code, proper syntax, methods of commenting and more. It is a great resource for new coders to learn proper formatting and syntax rules.
Coming from an ASP background, I wrote VBScript styled code when I first got into PHP. I thought it was great that I could still use the familiar If...End If type of syntax. Sinful, simply sinful.
While many people are indifferent to code formatting, or hold it up as a sacred form of personal expression, following an accepted set of rules will help everyone.
