Stuck on a multiple condition statement


Recommended Posts



I am trying to learn PHP and  I have spent the morning trying to sort out something seemingly simple  but it is not working for me.


I want to write a statement which says: if session variable "one" is empty or if session variable "two" is not equal to "svValue" then do this:


if ((empty ($_SESSION["One"])) || if ($_SESSION["Two"] != "svValue ) {

do this;



Could you point out the mistake(s) in my syntax?

Thank you!  Just to clarify, shouldn't the double quotes be closed after svValue? In my original question I made a typo and didn't close the quotes.


So would this be correct (just closed the quotes)?


if( empty($_SESSION["One"]) || ($_SESSION["Two"] != "svValue" ) ) {
do this;

Thank you for your help.  You got the typo form my original.


Just an FYI, there are a few more values that will qualify as 'empty'.  From the manual (empty):


The following things are considered to be empty:


    * "" (an empty string)

    * 0 (0 as an integer)

    * "0" (0 as a string)

    * NULL

    * FALSE

    * array() (an empty array)

    * var $var; (a variable declared, but without a value in a class)
