Hi
Just looking at your last post, if what is in your x.php file is as you wrote, you missed the $ string sign at the front of the vars, should be:
x.php
<?
$var1='<table id =\"1\"><tr><td>first table</tr></td></table><br><br>';
$var2='<table id=\"2\"><tr><td>Second table</tr></td></table>';
?>
ALSO. Note the slashes in front of double quotes. Without these PHP sees your code like this
x.php
<?
var1='<table id ="
/ above line has error no end of line ; /
1"><tr><td>first table</tr></td></table><br><br>';
/above line has no operation/function /
var2='<table id="
/ above line has error no end of line ; /
2"><tr><td>Second table</tr></td></table>';
/above line has no operation/function /
?>
Well, you get the idea!

PS, what editor do you use. A decent one would highlight these errors for you. I use AceHTML pro and it puts the error in pink!
