problems with php and rtf

[Bethesthel]

i got to read some data out of a database and fill a rtf-file with the data..
the string_replaces work fine, everything's alright, but i have a problem:

the data is shown in a table like this:
name | [name]
lastname | [lastname]
street | [street]

when something like the [street] has no value in the database, the whole table line should not show up..

any ideas?
