if  strpos  string   word      FALSE           not found         Note that strpos   is case sensitive  if you want a case-insensitive search  use stripos   instead   Also note the      forcing a strict equality test  strpos CAN return a valid 0 if the  needle  string is at the start of the  haystack   By forcing a check for an actual boolean false  aka 0   you eliminate that false positive

Use strpos  If the string is not found it returns false  otherwise something that is not false  Be sure to use a type-safe comparison       as 0 may be returned and it is a falsy value   if  strpos  string   substring      false           substring is not found in string    if  strpos  string   substring2      false           substring2 is found in string
