variable on the article

Hello,
I have article that has few variables like this
<txp:php> $abcd=‘xx’;
</txp:php>

About 50 lines of HTML code in between, then

<txp:php> echo $abcd;
</txp:php>

I get this error:

Tag error: <txp:php> echo $abcd;
</txp:php> -> Warning: Undefined variable $abcd Issue detected while parsing form None on page testing_four

why article doesn’t recognize the variable on same page ? what I’m going wrong.

This one works, if within same php tag.
Tag error: <txp:php> $abcd=‘xx’; echo $abcd;
</txp:php>

Thank you

Each <txp:php> block is a separate entity. To make variables persist across them, you must register them as globals:

<txp:php>
    global $abcd;
    $abcd = 'xx';
</txp:php>

<!-- your code -->

<txp:php>
    global $abcd;
    echo $abcd;
</txp:php>
