What does “===” mean?

i am seeing === often in php statements, but don't know what it mean. eg if ($pwd === PwdHash($pass,substr($pwd,0,9))). thanks

It tests equality, but unlike == it requires that the two operands be of the same type as well as value.

For instance, "1" == 1 will be true, but "1" === 1 is false because the type is different.

php has two types of equal comparison operator == and ===

== check for the equalization but not strict mean it will return true for ('123'==123)

=== is a strict equal operator it will return false for the ('123'===123)
