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

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
