将csv保存到服务器而不是下载

Question

I have a php page that takes my query results and saves them to a csv, which then prompts to download the csv file (all which is working fine). What I need is for the file to save in the same location on the server but I cannot seem to get it to work. Any idea how to save to the server rather than download?

<?php

// Database Connection

include "connection.php"; //Connect to Database

// Fetch Record from Database

$output = "";
$sql = mysql_query("select '$select' from'$from' where'$where'"
$columns_total = mysql_num_fields($sql);

// Get The Field Name

for ($i = 0; $i < $columns_total; $i++) {
$heading = mysql_field_name($sql, $i);
$output .= '"'.$heading.'",';
}
$output .="
";

// Get Records from the table

while ($row = mysql_fetch_array($sql)) {
for ($i = 0; $i < $columns_total; $i++) {
$output .='"'.$row["$i"].'",';
}
$output .="
";
}

// Download the file

$filename = "file.csv";
header('Content-type: application/csv');
header('Content-Disposition: attachment; filename='.$filename);
exit;
?>

Answer 1

Just use file_put_contents() function to save your CSV file into your server:

file_put_contents('yourfile.csv', $output);

So your code would be like:

<?php

// Database Connection

include "connection.php"; //Connect to Database

// Fetch Record from Database

$output = "";
$sql = mysql_query("select '$select' from'$from' where'$where'"
$columns_total = mysql_num_fields($sql);

// Get The Field Name

for ($i = 0; $i < $columns_total; $i++) {
$heading = mysql_field_name($sql, $i);
$output .= '"'.$heading.'",';
}
$output .="
";

// Get Records from the table

while ($row = mysql_fetch_array($sql)) {
for ($i = 0; $i < $columns_total; $i++) {
$output .='"'.$row["$i"].'",';
}
$output .="
";
}

// Download the file

$filename = "file.csv";
file_put_contents($filename, $output);
