I want to replace _ with \_, % with \% and & with \&.

Under PHP4.0.3pl1 (tested) and lower the following Code worked as expected:
$text = "Test with_ and %";
$text = preg_replace("/([_%&])/","\\\\1",$text);
echo $text;

But under PHP4.0.4pl1 the output is:
Test with\\1 and \\1

PHP is compiled as Module with Apache.

Thank you,
