Default PHP If statement issue

Hi guys,

I need a little bit of help with solving an issue which we are getting with this php statement.

PHP Code:
if(isset($value)) { 
echo 
"true"
} else { 
echo 
"false"

Currently whats happening is that both true and false appear... we've never seen this happen before and wanted to know if you guys would have clue why both echo at the same time.

PHP Code:
if ($value)
{
    echo 
'true';
}
else
{
    echo 
'false';

isset() simply checks if the variable exists, regardless of value.

The value returned has nothing to do with the issue...

Right, sorry, I misinterpreted your question. That should never happen, and really can't happen, as an if/else statement can only run either block, not both.

Run this and copy and paste the exact output (preferably from the HTML source):

PHP Code:
echo '------- START -------';

if(isset(
$value))
{
    echo 
'true';
}
else
{
    echo 
'false';
}

echo 
'------- VAR -------';

var_dump($value);

echo 
'------- END -------'

Thank you for the help.
