Question

I have a weird problem. I have checking a php string like this:

On Page1

$_SESSION['test']=<a value from a row fetched from db>

On Page2

$myVar=$_SESSION['test'];
echo $myVar;

if($myVar=="This is the match string"){
echo "Matched";
}else{
echo "Not Matched";
}

I can see that $myVar echoed out the same string that I am checking again “This is the match string” but it still goes into else. I tried:

$myVar=(string)trim($_SESSION['test']);

but it still goes into else. What can be the issue? Any idea?

Answer 1

It’s possible there are trailing blank spaces (space,tab, newline).

Try

$myVar = trim( $_SESSION['test'] );

Doing var_dump( $_SESSION[‘test’] ); might also reveal the problem.
