[RESOLVED] Output makes no sense

scrupul0us

<?php 
$go =  $_SERVER['QUERY_STRING'];

echo $go."<br/>";

if (!isset($go) || empty($go) || $go='')
{
echo "Home";
}
else
{
echo "You are headed towards: ".$go.";";
}			
?>

if i surf to:

/?1
/?2
/?3
/?4
etc...

it outputs the query value on this line:

echo $go."<br/>";

but on the control structure, i get a blank space in this output:

echo "You are headed towards: ".$go. ";";

what am i doing wrong?

if (!isset($go) || empty($go) || $go[b][color=red]==[/color][/b]'')

BTW, if(empty($go)) by itself is functionally identical to that entire if clause.

scrupul0us

trimmed it up...

how does $go=='' SET it equal to nothing... shouldn't it be checking to see IF its equal to nothing, or does the single equal just instinctively do that operation... would seem silly to do so inside an IF clause no?

NogDog

You didn't have it as $go=='', you only had a single "=", thus it was assigning the value instead of comparing it.

Not exactly, if you mean that if (empty($go)) is identical to if (!isset($go) || $go=''). For example, the first will succeed and the second fail if $go equals (string) "0".

Edit: Never mind; I guess when you said "entire" you meant "entire". 🙂
