Is there any difference between == and === in php? both seem to work fine for me when i use them in a conditional statement. I am very new to programming in PHP. Please consider this and answer in simple words.

  • $a == $b

    • Equal true : if $a is equal to $b , after type juggling.

  • $a === $b

    • Identical true : if $a is equal to $b , and they are of the same type .

    Identical:

    $a === $b

    TRUE if $a is equal to $b , and they are of the same type. (introduced in PHP 4 )

    Equal:

    $a == $b

    TRUE if $a is equal to $b after type juggling.
