Write CSV To File Without Enclosures In PHP

Question

Is there a native function or solid class/library for writing an array as a line in a CSV file without enclosures? fputcsv will default to \" if no

Answer 1

I use tricky way to remove double quote, but only in Linux

....
fputcsv($fp, $product_data,"\t");
....
shell_exec('sed -i \'s/"//g\' /path/to/your-file.txt ');

Answer 2

This is what I use to put standard CSV into an array...

function csv_explode($delim=',', $str, $enclose='"', $preserve=false){
        $resArr = array();
        $n = 0;
        $expEncArr = explode($enclose, $str);
        foreach($expEncArr as $EncItem){
                if($n++%2){
                        array_push($resArr, array_pop($resArr) . ($preserve?$enclose:'') . $EncItem.($preserve?$enclose:''));
                }else{
                        $expDelArr = explode($delim, $EncItem);
                        array_push($resArr, array_pop($resArr) . array_shift($expDelArr));
                        $resArr = array_merge($resArr, $expDelArr);
                }
        }
        return $resArr;
} 

You can then output whatever you want in a foreach loop.

Chose the solution depends on your application. For some case own code for csv is needed. In case 1 (See result chr0), case 2 (chr127) and case 3 (chr127) the data will be modified(bad thing). Instead use something like this, thanks @oops:

<?php
$fields = array(
    "field 1","field 2","field3hasNoSpaces"
);
fputs(STDOUT, implode(',', $fields)."\n");


case 1. `fputcsv($f, $array, $delimiter, car(0))`
See result [chr0][1]
case 2. `fputcsv($f, $array, $delimiter, car(127))`
[chr127][2]
case 3. `fputcsv($f, $array, $delimiter, ' ')`
[onespace][3]
case 4. Own code:

 or [Ansyori](https://stackoverflow.com/a/51981613)
 or [zeros-and-ones](https://stackoverflow.com/a/38778459)
produces better results.

Well car(0) didn't work out as the NULL value will most likely choke most csv parsers.

I ended using fputcsv() to build the initial file, then went through and removed all quotes. Elegant? Maybe not, but it got the job done :).

Answer 5

Using "chr(0)" adds a character to the file. After doing some investigation and checking the ASCII Table, I've ended up using the following

fputcsv($fp, $aLine, $sDelimiter, chr(127));

No issues with extra characters.

Whats wrong with good old fwrite()?

function encloseString($field){
    return ($field) ? '"' . $field . '"' : null;
}

$delimiter = ';';
$data = ["data_field_1", "data_field_2", "data_field_3"];

$fp = fopen("some-file.csv", 'w');

for($i = 0;$i<100000;$i++) {
    fwrite($fp, implode($delimiter, array_map('encloseString', $data) . "\n");
}

fclose($fp);

(Obviously you need to make sure the data in $data is escaped first)
