Using AND/OR in if else PHP statement

Question

How do you use 'AND/OR' in an if else PHP statement? Would it be:

1) AND

if ($status = 'clear' AND $pRent == 0) {     mysql_query("UPDATE rent                      SET dNo = '$id',                          status = 'clear',                          colour = '#3C0'                    WHERE rent.id = $id"); }  

2) OR

if ($status = 'clear' OR $pRent == 0) {     mysql_query("UPDATE rent                      SET dNo = '$id',                          status = 'clear',                          colour = '#3C0'                    WHERE rent.id = $id"); }  

Answer 1

Yes. The answer is yes.

Two things though:

• Many programmers prefer && and || instead of and and or, but they work the same (safe for precedence).
• $status = 'clear' should probably be $status == 'clear'. = is assignment, == is comparison.
