In PHP, what is the difference between the '==' and '===' operators?
- '==' performs loose comparison
- '===' performs strict comparison
- '==' checks only value equality
- '===' checks value and type equality
'==' checks if the values are equal, while '===' checks both the values and data types. '===' is stricter and will return true only if both the value and data type match. '==' is more permissive.
