php fputcsv 和封闭字段

Question

我正要提出与此处提出的问题相同的问题.... Forcing fputcsv to Use Enclosure For *all* Fields

问题是

When I use fputcsv to write out a line to an open file handle, PHP will add an enclosing character to any column that it believes needs it, but will leave other columns without the enclosures.

For example, you might end up with a line like this

11,"Bob ",Jenkins,"200 main st. USA ",etc

Short of appending a bogus space to the end of every field, is there any way to force fputcsv to always enclose columns with the enclosure (defaults to a ") character?

答案是:

No, fputcsv() only encloses the field under the following conditions

/* enclose a field that contains a delimiter, an enclosure character, or a newline */
if (FPUTCSV_FLD_CHK(delimiter) ||
  FPUTCSV_FLD_CHK(enclosure) ||
  FPUTCSV_FLD_CHK(escape_char) ||
  FPUTCSV_FLD_CHK('\n') ||
  FPUTCSV_FLD_CHK('\r') ||
  FPUTCSV_FLD_CHK('\t') ||
  FPUTCSV_FLD_CHK(' ')
)

There is no "always enclose" option.

我需要创建一个 CSV 文件以包含每个字段...什么是最佳解决方案？

滚动你自己的函数 - 这并不难:

 function dumbcsv($file_handle, $data_array, $enclosure, $field_sep, $record_sep)
 {
     dumbescape(false, $enclosure);
     $data_array=array_map('dumbescape',$data_array);
     return fputs($file_handle, 
         $enclosure 
         . implode($enclosure . $field_sep . $enclosure, $data_array)
         . $enclosure . $record_sep);
 }
 function dumbescape($in, $enclosure=false)
 {
    static $enc;
    if ($enclosure===false) {
        return str_replace($enc, '\\' . $enc, $in);
    }
    $enc=$enclosure;
 }
