+## While Loops
+A `while` loop executes statements within the loop as long as the loops condition is met. 
+
+### Syntax:
+```php
+$x = 0;
+while ($x < 11) {
+    statement1;
+    $x++;
+}
+```
+
+**Note:** The block code must have a statement that changes or increments the condition.  Otherwise an infinite loop could result.
