C was my first "real" language (BASIC was the one before it). I learned using the great C for Dummies by Dan Gookin[1], which at the time consisted of two massive volumes comprising over 1000 pages. Good times.

Nowadays most of my work is PHP and Node.js, but if you know C, you will have no problems learning PHP.
