This will not do what you expect it to. Since 'John' is the first thing 
in the string strpos will return 0 causing the condition to evaluate to 
false.

As per the documentation for strpos you should compare the value *and 
type* of the variable returned by strpos against false to check for 
non-existance.

if (strpos($name, 'John') !== false) { ... }
