如何在php的csv中将sql查询结果插入一行？

Question

The following code output the sql query result into a csv file :

CODE

<?php
// Report all errors except E_NOTICE   
error_reporting(E_ALL ^ E_NOTICE); 

//connection file
include("connection.php");  

$query      = 'SELECT resting_blood_sugar,serum_cholesterol,thalach,oldpeak,result,date from hd_test WHERE patient_id = 2';         
$output = fopen('N:\oldpatientgraph.csv', 'w');
$result = mysqli_query($link,$query);

// loop over the rows, outputting them
while ($row = mysqli_fetch_assoc($result)) fputcsv($output, $row);

?>

OUTPUT

The csv file contains output in following format :

1,1,1,1,1,11-1-2015 #line1

2,3,1,4,2,1-1-2000 #line2

Whereas i want to output the result in one line as follows :

1,1,1,1,1,11-1-2015,2,3,1,4,2,1-1-2000 #line1

Anyone here who knows how to do this ??

Answer 1

just concancenate the row, like below :

// loop over the rows, outputting them
$arr1 = array();
while ($row = mysqli_fetch_assoc($result)){
   $arr1 = array_merge($arr1,array_values($row));
}
fputcsv($output,$arr1);

Answer 2

You can try this

$output = fopen('N:\oldpatientgraph.csv', 'w');
$csvString = '';
$index = 0;
while ($row = mysqli_fetch_assoc($result)){
  if ($key) {
    $csvString.=',';
  }
  $csvString .= implode(',',array_values($row)); #Array values to string
  $index = 1;
}

fwrite($output, $csvString); #Write string to file
fclose($output);

Note : Above code will give you all data in 1 line.
