PHP, javascript n xhtml --- problem comparing variable

[CstAn]

i got a parent window that call out the child window......

in the child window i successful get the value from the parent window by using opener.document.getElementById.


because i want show the xhtml based on the value i get, so i had using PHP to compare with the language i get.
but the problem now is i cant compare although the value same as i get.

for example:
in parent window:
<input type = "hidden" name = "text1" id = "text1" value = "abc">

in child window:
<? $getValue = "<script language = 'language'>document.write(opener.document.getElementById('text1').value);</script>";

if($getValue == "abc")
{
echo"<table><tr><td>same</td></tr></table>";
}
else
{
echo "<table><tr><td>different<td></tr></table>";
}
?>

but the problem now is, it always show "different" message. y like that de??

i try to show d $getValue 's value, it show out "abc".

anyone can help me n tell me what is the problem??
