Question

for some of my php pages, i use the $_SESSION to determine if a user is signed in, the code is:

if(isset($_SESSION['USERID'])&&$_SESSION['USERID']>=0&&is_numeric($_SESSION['USERID']));

for whatever reason, this if statement is being ignored, I have tested the $_SESSION to make sure that the value is empty by trying

$session=$_SESSION['USERID']; echo"$session"; the result is blank.

now at the end of php file i want to use an else follow the closing if bracket, this is creating the error of:

Parse error: syntax error, unexpected T_ELSE 

This is extremely frustrating, why would this occur?

Answer 1

You’ve got a semicolon after your if. Take it out, and it won’t be ignored, plus your else will work.

if(isset($_SESSION['USERID'])
   && $_SESSION['USERID'] >= 0
   && is_numeric($_SESSION['USERID']));
#-------------------------------------^ shouldn't be here.
