Answer
== compares values with type juggling. === compares both value and type.
Quick Answer
== (loose comparison): compares values with type coercion - "1" == 1 is true, "" == false is true, "0" == false is true. === (strict comparison): compares both value and type - "1" === 1 is false. Always use === in PHP to avoid unexpected type juggling behavior. The loose comparison table in PHP has many non-obvious results that cause bugs.
