It's unrealistic to require the field enclosure to be one character because it's very common to have "empty string" as the field delimiter (especially when TAB is used as field delimiter).



I tried to use "\0" as the field enclosure, hoping that'd be interpreted as an empty string, but fputcsv (in PHP5) translated it into literal.



By the way, fputcsv wrongly adds the field enclosures whenever a field contains a space. The expected behavior should be adding the field enclosures when a field contains a field delimiter.

Here is an adaptation to boonerunner's function for fputcsv.

It uses a 2-dimensional array.

Each sub-array is a line in the csv file which then ends up being seperated by commas.



function fputcsv($filePointer,$dataArray,$delimiter=",",$enclosure="\""){

    // Write a line to a file

    // $filePointer = the file resource to write to

    // $dataArray = the data to write out

    // $delimeter = the field separator

     

    // Build the string

    $string = "";

  

    // for each array element, which represents a line in the csv file...

    foreach($dataArray as $line){



        // No leading delimiter

        $writeDelimiter = FALSE;

        

        foreach($line as $dataElement){ 

            // Replaces a double quote with two double quotes

            $dataElement=str_replace("\"", "\"\"", $dataElement);

            

            // Adds a delimiter before each field (except the first)

            if($writeDelimiter) $string .= $delimiter;

            

            // Encloses each field with $enclosure and adds it to the string

            $string .= $enclosure . $dataElement . $enclosure;

            

            // Delimiters are used every time except the first.

            $writeDelimiter = TRUE;

        }

        // Append new line

        $string .= "\n";



    } // end foreach($dataArray as $line)



    // Write the string to the file

    fwrite($filePointer,$string);

}

Here is an adaption of the above code that adds support for double quotes inside a field. (One double quote is replaced with a pair of double quotes per the CSV format).



<?php

 function fputcsv($filePointer,$dataArray,$delimiter,$enclosure)

  {

  // Write a line to a file

  // $filePointer = the file resource to write to

  // $dataArray = the data to write out

  // $delimeter = the field separator

  

  // Build the string

  $string = "";

  

  // No leading delimiter

  $writeDelimiter = FALSE;

  foreach($dataArray as $dataElement)

   {

    // Replaces a double quote with two double quotes

    $dataElement=str_replace("\"", "\"\"", $dataElement);

    

    // Adds a delimiter before each field (except the first)

    if($writeDelimiter) $string .= $delimiter;

    

    // Encloses each field with $enclosure and adds it to the string

    $string .= $enclosure . $dataElement . $enclosure;

    

    // Delimiters are used every time except the first.

    $writeDelimiter = TRUE;

   } // end foreach($dataArray as $dataElement)

  

  // Append new line

  $string .= "\n";

  

  // Write the string to the file

  fwrite($filePointer,$string);

  }

?>

What about cells that span multiple lines?  This function allows for cells to contain newlines:



function fputcsv($handle, $row, $fd=',', $quot='"')

{

   $str='';

   foreach ($row as $cell) 

   {

      $cell = str_replace($quot, $quot.$quot, $cell);

         

      if (strchr($cell, $fd) !== FALSE || strchr($cell, $quot) !== FALSE || strchr($cell, "\n") !== FALSE) 

      {

         $str .= $quot.$cell.$quot.$fd;

      } 

      else 

      {

         $str .= $cell.$fd;

      }

   }



   fputs($handle, substr($str, 0, -1)."\n");



   return strlen($str);

}

I found the following problems with the below function:



- when calling str_replace(), you must assign $cell the return value or nothing gets saved



- 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



- Excel seems to quote not only fields containing commas, but fields containing quotes as well, so I've added another strchr() for quotes; I'm not saying Microsoft knows the correct way for sure, but it seems reasonable to me



- the original function put a space after each comma; that might be legal, I don't know, but I've never seen it (and I don't think it is, because then how would you indicate you wanted a field to start with a space other than by quoting it?)



- the original function didn't correctly return the length of the data outputted



Here's the function, fixed up a bit:



function fputcsv($handle, $row, $fd=',', $quot='"')

{

   $str='';

   foreach ($row as $cell) {

       $cell=str_replace(Array($quot,        "\n"),

                         Array($quot.$quot,  ''),

                         $cell);

       if (strchr($cell, $fd)!==FALSE || strchr($cell, $quot)!==FALSE) {

           $str.=$quot.$cell.$quot.$fd;

       } else {

           $str.=$cell.$fd;

       }

   }



   fputs($handle, substr($str, 0, -1)."\n");



   return strlen($str);

}

The function in the prior comment doesn't escape quotes in fields, here mine:



function fputcsv($handle, $row, $fd=',', $quot='"')

{

    $str='';

    foreach ($row as $cell) {

        str_replace(Array($quot,        "\n"),

                    Array($quot.$quot,  ''),

                    $cell);

        if (strchr($cell, $fd)) {

            $str.=$quot.$cell.$quot.$fd.' ';

        } else {

            $str.=$cell.$fd.' ';

        }

    }



    fputs($handle, substr($str, 0, -2)."\n");



    return $str-1;

}

Here's a simplistic fputcsv function that you can use until the real one gets out of CVS:



function fputcsv($filePointer, $dataArray, $delimiter, $enclosure){

      // Write a line to a file

      // $filePointer = the file resource to write to

      // $dataArray = the data to write out

      // $delimeter = the field separator

      

      // Build the string

      $string = "";

      $writeDelimiter = FALSE;

      foreach($dataArray as $dataElement){

        if($writeDelimiter) $string .= $delimiter;

        $string .= $enclosure . $dataElement . $enclosure;

        $writeDelimiter = TRUE;

        } // end foreach($dataArray as $dataElement)

      

      // Append new line

      $string .= "\n";

      

      // Write the string to the file

      fwrite($filePointer, $string);

      

      } // end function fputcsv($filePointer, $dataArray, $delimiter)
