Yes I understand it, but it's an excepted behaviour of the ZendEngine.
Just add put a backslash before '$'.
Thanks for your report.

I think you misunderstood the report. The $1 was the literal value
(note the single quotes around the string). When IT.php processes the
value it's evaluated instead of being taken literally -- I wouldn't
think that'd be expected behavior. Try this modified example:
<?php
require_once('HTML/IT.php');
$value = 'I have $1 in my pocket';
$t = new IntegratedTemplate;
$t->setTemplate('{x}', TRUE, TRUE);
$t->setVariable('x', $value);
print $value."\n";
$t->show();
?>
This prints:
I have $1 in my pocket
I have in my pocket
The first time it's printed correctly, but after it's processed in
IT.php it's printed incorrectly.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report

Isn't this the expected behaviour? It's certainly what would happen if
used $whatever in a string anywhere else in PHP - I think people would
just get confused if their variables suddenly disappeared.
If you want to include a $ sign in the string, you need to escape it
(\$).

When an IT variable is set with "$" in the value, the value isn't taken
literally. Example:
<?php
require_once('HTML/IT.php');
$t = new IntegratedTemplate;
$t->setTemplate('{x}', TRUE, TRUE);
$t->setVariable('x', 'I have $1 in my pocket');
$t->show();
?>
The above prints "I have in my pocket".
A solution would be to use str_replace() instead of preg_replace() when
substituting the value. Patch is below:
