How about this?
$adjusted_content = preg_replace('/\$([0-9]+\.[0-9]{2})/e',
'sprintf("$%01.2f",$1*0.05+$1)', $content);
It will take each occurrence of something like $23.22 and match the
23.22 part. It will then evaluate the code
sprintf("$01.2f",$1*0.05+$1)
where $1 is the 23.22 or whatever was matched. The sprintf will format
the output so that it's only two decimals.
Hope that helps.
