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) { ... }
