The 3 different equals

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.

  • what is your mean of *same type* ? iIf `$a == $b` be true, then certainly they are of the same type. is it not ? can you give me a example that they be `==` (true) but `===` (false) ? – Shafizadeh Aug 11 '15 at 13:18
  • @Sajad here http://www.php.net/manua/en/language.operators.comparison.php is a lot of examples – evilone Aug 11 '15 at 13:36
  • @Shafizadeh http://www.7codes.info/post/4/difference-between-==-and-=== in example "22" is string and 22 is integer. They are not the same type because one is string, another integer. With `==` they are equal, but with `===` are not equal – user2360831 May 24 '19 at 06:16

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.
