Here's something I put together this morning.

It allows you to read rows from your CSV and get values based on the name of the column. This works great when your header columns are not always in the same order; like when you're processing many feeds from different customers. Also makes for cleaner, easier to manage code. I used fgetcsv to read pipe-delimited data files, and ran into the following quirk.

In this particular case it is easy to spot, but my script was processing thousands of records and it took me some time to figure out what went wrong. The annoying thing is, that there doesn't seem to be an elegant fix. So you'd have to resort to a solution where you use an extremely unlikely enclosure, but since the enclosure can only be one character long, it may be hard to find. I've had alot of projects recently dealing with csv files, so I created the following class to read a csv file and return an array of arrays with the column names as keys.

The only requirement is that the 1st row contain the column headings. I only wrote it today, so I'll probably expand on it in the near future. For anyone else struggling with disappearing non-latin characters in one-byte encodings - setting LANG env var as the manual states does not help at all.

The fgetcsv function seems to follow the MS excel conventions, which means: - The quoting character is escaped by itself and not the back slash. Let's use the double quote " as the quoting character: Two double quotes "" will give a single " once parsed, if they are inside a quoted field otherwise neither of them will be removed.

If it is not inside a quoted field it will stay. So previous comments stating the opposite are wrong, unless they are using a different PHP version I am using 4. So fgetcsv if actually very complete and can deal with every possible situation. It does need help for macintosh line breaks though, as mentioned in the help files. I wish I knew all this from the start. From my own benchmarks fgetcsv strikes a very good compromise between memory consumption and speed.

Same for leading and trailing spaces. Here is a breakdown of fgetcsv 's behaviour. Its structure is equivalent to " or in other words, an open enclosure, some data and no closing enclosure.

If there are any, they could end up being removed as well, depending on the function used.
