If statement

Hi,

I use a sample code showed in php.net website manual with my
conditions, and the result is always true.

<?php if ( $username="myusername" AND $password="mypassword" ) { ?>

True

<?php } else { ?>

False

<?php } ?>

Where's the bug?

Thanks in advance

That's because '=' is an assignment and '==' is what you are looking for.

The PHP equals (=) operator assigns variables. So, when your first line is
this...

<?php if ( $username="myusername" AND $password="mypassword" ) { ?>

.... you are assigning $username the value "myusername" and $password the
value "mypassword". In PHP, any string that does not equal "" or "0" is
considered to be true. You must use the comparison operator (==) instead to
compare the two variables to their respective strings. So your first line
should be changed to this:

<?php if ( $username=="myusername" AND $password=="mypassword" ) { ?>
