PHP to Excel (csv)

Hi I have following problem. Some data retreived from mysql db I need to send to the user as a *.csv file. Usually I separate fields (usually double quoted) with comma (,) or semicolomn (;) and the records with cr/lf (Windows) It works fin until I do not have cr/lf in any of the fields. Unfortunately the last field is TEXT type and may have more that one cr/lf inside (as data). When this is the case the *,csv file cannot be open correctly in Excel. If there are cr/lf in any field it is split in Excel as a separate row and the record structure is broken.\ Any idea how could solve this? Thank you Ivo
