+## Variable Naming
+
+Variables should always be named descriptively and concisely. Single character variables should never be used unless otherwise specified in a language
+specific style guide.
+
+#### Bad Variable Naming
+
+```php
+foreach ($items as $i) {
+    //do things in the iteration
+}
+```
+
+#### Good Variable Naming
+
+```php
+foreach ($items as $item) {
+    //do things in the iteration
+}
+```
