I'm an experienced programmer (20 years+) but am new to web programmer. Any suggestions on where someone like me might start learning about PHP? Just start reading PHP For Dummies or are there better options?
Are you fluent in C++? If so, you can learn PHP by following examples in code. The base structure is the same, you just go about putting dollar signs in front of your variables. (Ok, this is a very simple point of view.) I started with PHP using my limited HTML knowledge and form processing demo code.
In any case, php.net will probably be your best friend. PHP has EXCELLENT documentation, so it's worth checking there first. They'll even tell you some of the common security issues.
