Print syntax for export to csv - php

Question

I want to print to excel as csv. This is where I am so far working from the answers.
<?php
$dbh = dbh_get();
header('Content-type: application/csv');
header("Content-Disposition: inline; filename=file.csv");
readfile('file.csv');
$sql = 'select t.*
from old t
where t.entered >= ? and t.entered < ?
and t.status <> \'cancel\'
and t.ccy = \'USD\'
order by id desc';
$stmt = $dbh->prepare($sql);
$v = array();
$v[] = $date->format(DateTime::ISO8601);
$v[] = $dateEnd->format(DateTime::ISO8601);
$numRows = 0;
$stmt->execute($v);
while (true) {
$r = $stmt->fetch();
if (is_bool($r)) break;
$numRows++;
$bop = $r['comments'];
$bop1 = strtok($bop, " "); //remove all but first word
$bop2 = substr(strstr($bop," "), 1); //remove first word and space
$headers = ['PLACE','YEAR','MONTH','COY','NT','TOPS','BOP','COUNTRY','REC','SENT','DESC'];
$fields = ["Old",2015,$textDate,$r['cols'],$r['nt'],$bop1,"NTR",$r['name'],$r['first_name'],$r['last_name'],$bop2];
$fp = fopen('file.csv', 'w');
fputcsv($fp, $headers);
fputcsv($fp, $fields);
fclose($fp);
}
dbh_free($dbh);
Still not working with this I get one line of code printed to screen, no download. What I need is to download the csv file so I can open it with excel.

Don't punish yourself by manually building a CSV. Use PHP's built in functionality instead.
<?php
$bop1 = 'bop1';
$bop2 = 'bop2';
$textDate = '2017-04-13';
$r = [
'ccy' => 'ccy',
'amount' => 'amount',
'name' => 'name',
'first_name' => 'first_name',
'last_name' => 'last_name',
];
$headers = ['column1','column2','column3','column4','column5','column6','column7','column8','column9','column10','column11'];
$fields = ["Old","2015",$textDate,$r['ccy'],$r['amount'],$bop1,"NTR",$r['name'],$r['first_name'],$r['last_name'],$bop2];
$fp = fopen('file.csv', 'w');
fputcsv($fp, $headers);
fputcsv($fp, $fields);
fclose($fp);
header('Content-type: application/csv');
header("Content-Disposition: inline; filename=file.csv");
readfile('file.csv');
Here's an updated example using your updated code:
<?php
$dbh = dbh_get();
$sql = 'select t.*
from old t
where t.entered >= ? and t.entered < ?
and t.status <> \'cancel\'
and t.ccy = \'USD\'
order by id desc';
$stmt = $dbh->prepare($sql);
$v = array();
$v[] = $date->format(DateTime::ISO8601);
$v[] = $dateEnd->format(DateTime::ISO8601);
$stmt->execute($v);
$fp = fopen('file.csv', 'w');
$headers = ['PLACE','YEAR','MONTH','COY','NT','TOPS','BOP','COUNTRY','REC','SENT','DESC'];
fputcsv($fp, $headers);
while ($r = $stmt->fetch()) {
$bop = $r['comments'];
$bop1 = strtok($bop, " "); //remove all but first word
$bop2 = substr(strstr($bop," "), 1); //remove first word and space
$fields = ["Old",2015,$textDate,$r['cols'],$r['nt'],$bop1,"NTR",$r['name'],$r['first_name'],$r['last_name'],$bop2];
fputcsv($fp, $fields);
}
fclose($fp);
dbh_free($dbh);
header('Content-type: application/csv');
header("Content-Disposition: inline; filename=file.csv");
readfile('file.csv');

Answer 2

You can do something like this:
$data = ['Old', '2015', $textDate];
file_put_contents('pathTofile.csv', implode(';', $data) . PHP_EOL, FILE_APPEND);
Update:
Now is some code more here, compared to the posted one liner. Just change the Content-Disposition header to this:
header('Content-Disposition: attachment; filename="'.basename('file.csv').'"');
it forces a download. See Content-Disposition and Read File
