PHP code to convert a MySQL query to CSV

What is the most efficient way to convert a MySQL query to CSV in PHP please   It would be best to avoid temp files as this reduces portability  dir paths and setting file-system permissions required    The CSV should also include one top line of field names

If you d like the download to be offered as a download that can be opened directly in Excel  this may work for you   copied from an old unreleased project of mine    These functions setup the headers    function setExcelContentType         if headers sent            return false       header  Content-type  application vnd ms-excel        return true     function setDownloadAsHeader  filename        if headers sent            return false       header  Content-disposition  attachment  filename      filename       return true      This one sends a CSV to a stream using a mysql result  function csvFromResult  stream   result   showColumnHeaders   true        if  showColumnHeaders             columnHeaders   array             nfields   mysql num fields  result           for  i   0   i  lt   nfields   i                   field   mysql fetch field  result   i                columnHeaders      field- gt name                    fputcsv  stream   columnHeaders               nrows   0      while  row   mysql fetch row  result             fputcsv  stream   row            nrows               return  nrows      This one uses the above function to write a CSV to a file  given by  filename  function csvFileFromResult  filename   result   showColumnHeaders   true         fp   fopen  filename   w         rc   csvFromResult  fp   result   showColumnHeaders       fclose  fp       return  rc      And this is where the magic happens     function csvToExcelDownloadFromResult  result   showColumnHeaders   true   asFilename    data csv         setExcelContentType        setDownloadAsHeader  asFilename       return csvFileFromResult  php   output    result   showColumnHeaders       For example    result   mysql query  SELECT foo  bar  shazbot FROM baz WHERE boo    foo     csvToExcelDownloadFromResult  result
