when using strchr(), you should explicitly check != FALSE, or it'll treat a return value of 0 (found the character at string position 0) as FALSE when calling str_replace(), you must assign $cell the return value or nothing gets saved "orange, burnt","pink, hot",violet,indigo White,gold,"purple, imperial","grey, slate" The test should produce something like the following: This is how I solved the problem without rewriting fputcsv. In general I found myself wanting to get the result as a string rather than writing it to a file, and in particular I wanted to produce a CSV using an EOL that might not be the same as that on the server where I generated it. This replicates PHP5 functionality exactly, whereas the other examples here do not. I converted this from the PHP source code. If fputcsv fails to work for you (particularly with mysql csv imports), try this function as a drop-in replacement instead.Īrguments to pass in are exactly the same as for fputcsv, though I have added an additional $mysql_null boolean which allows one to turn php null's into mysql-insertable nulls (by default, this add-on is disabled, thus working identically to fputcsv ).
(Technically you could omit the headings array and just include it as the first row of the data, but it is often useful to keep this data stored in different arrays in practice.)Īlright, after playing a while, I'm confident the following replacement function works in all cases, including the ones for which the native fputcsv function fails. It takes two parameters + one optional parameter: the location of where the file should be saved, an array of data rows, and an optional array of column headings.

So quite simply, this function is used for outputting CSV data to a CSV file in a way that is safe for use with Windows applications. It would be fairly simple to modify this function to use another delimiter if need be and I leave that as an exercise to the reader. This function accommodates for that as well, by forcibly enclosing that first value in quotes (when this doesn't occur automatically). Secondly, if the first column heading / value of the CSV file begins with uppercase ID, certain Microsoft programs (ahem, Excel 2007) will interpret the file as being in the SYLK format rather than CSV, as described here: So this function changes the line endings accordingly. However, certain Microsoft programs (I'm looking at you, Access 97), will fail to recognize the CSV properly unless each line ends with \r\n. First, since PHP is generally *nix-based, it makes sense that the line endings are always \n instead of \r\n. In the field I learned a few things about generating CSVs that are not always obvious. I've created a function for quickly generating CSV files that work with Microsoft applications. Utility function to output a mysql query to csv with the option to write to file or send back to the browser as a csv attachment.
