I am using a CSV file to export a mysql table. How can I view it as a download file now that it is stored on Drive C: directly without any notification
<?php
$host = 'localhost'; // <-- db address
$user = 'root'; // <-- db user name
$pass = 'root'; // <-- password
$db = 'urs'; // db's name
$table = 'veiwresult'; // table you want to export
$file = 'alaa'; // csv name.
$link = mysql_connect($host, $user, $pass) or die("Can not connect." . mysql_error());
mysql_select_db($db) or die("Can not connect.");
$result = mysql_query(" SELECT ApplicantNum,name, averg,choice FROM veiwresult");
fputcsv($f, array('ApplicantNum','name','averg', 'choice'));
$timestamp = date('Ymd-His');
$f = fopen("C:/mycsv-{$timestamp}.csv", 'w');
// Headers
while($row = mysql_fetch_row($result))
{
fputcsv($f, $row);
}
fputcsv($f, $items_array);
fclose($f);
?>
If you want to store csv-file and then open it without any clicking, it`s impossible.
If you just wish to have it opened, open it in browser window via
header('Content-disposition: inline;filename=foobar.csv');
header('Content-Type: text/csv;charset=UTF-8');
echo $csv_content;
where $csv_content is a string with contents of csv-file. You cat get it this way
$csv_content = file_get_contents('c:/mycsv.csv');
To download it...
<?php
$host = 'localhost'; // <-- db address
$user = 'root'; // <-- db user name
$pass = 'root'; // <-- password
$db = 'urs'; // db's name
$table = 'veiwresult'; // table you want to export
$file = 'alaa'; // csv name.
$link = mysql_connect($host, $user, $pass) or die("Can not connect." . mysql_error());
mysql_select_db($db) or die("Can not connect.");
$result = mysql_query(" SELECT ApplicantNum,name, averg,choice FROM veiwresult");
fputcsv($f, array('ApplicantNum','name','averg', 'choice'));
$timestamp = date('Ymd-His');
$f = fopen("C:/mycsv-{$timestamp}.csv", 'w');
// Headers
while($row = mysql_fetch_row($result))
{
fputcsv($f, $row);
}
fputcsv($f, $items_array);
fclose($f);
header('Content-type: application/csv');
header('Content-Disposition: attachment; filename="mycsv-{$timestamp}"');
readfile('C:/mycsv-{$timestamp}.csv');
?>
This will still notify the user of the download, and depending on their settings they may need to accept the download. This functionality cannot be overridden of course.

I have the following code which I am using to download a CSV of the data to a file called Out of Area.csv
<?php
// START EXPORT OF LTHT DATA //
exportMysqlToCsv('Out of Area.csv');
// export csv
function exportMysqlToCsv($filename = 'Out of Area.csv')
{
$conn = dbConnection();
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql_query = "SELECT * FROM MDSData WHERE Downloaded IS NULL ORDER BY RegisteredCCG";
// Gets the data from the database
$result = $conn->query($sql_query);
$f = fopen('php://temp', 'wt');
$first = true;
while ($row = $result->fetch_assoc()) {
if ($first) {
fputcsv($f, array_keys($row));
$first = false;
}
fputcsv($f, $row);
} // end while
$sql_query = "UPDATE MDSData SET Downloaded='YES' WHERE Downloaded IS NULL";
// Gets the data from the database
if ($conn->query($sql_query) === TRUE) {
} else {
}
$conn->close();
$size = ftell($f);
rewind($f);
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Length: $size");
// Output to browser with appropriate mime type, you choose ;)
header("Content-type: text/x-csv");
header("Content-type: text/csv");
header("Content-type: application/csv");
header("Content-Disposition: attachment; filename=$filename");
fpassthru($f);
exit;
}
// db connection function
function dbConnection(){
$servername = "servername";
$username = "username";
$password = "password";
$dbname = "databasename";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
return $conn;
}
header('location:csv-upload-mds.php?week='.$SelectedWeek);
?>
However I have a column in my table called 'TownName' and I would like to loop through creating a CSV Named 'Out of Area - The Town Name Here.csv' for example 'Out of Area - Berkshire.csv'
Currently i've got to the stage where I can make it download 1 file with all the data in, however my issue comes when trying to download multiple files. Even if I duplicate the exportMysqlToCsv() call I get an error as this function can only be called once. So I need to put the loop inside an if statement I guess...
My thoughts are something like the following
$sqlquery = "SELECT * FROM MDSData WHERE Downloaded IS NULL GROUP BY REGISTERED CCG"
$result = $conn->query($sql_query);
while ($row = $result->fetch_assoc()) {
// Now I've looped through each CCG for each one I can set the file name and add the data to the file.
$filename = "Out of Area - " . $row["TownName"]. ".csv";
$sql_query = "SELECT * FROM MDSData WHERE Downloaded IS NULL ORDER BY RegisteredCCG";
// Gets the data from the database
$result = $conn->query($sql_query);
$f = fopen('php://temp', 'wt');
$first = true;
while ($row = $result->fetch_assoc()) {
if ($first) {
fputcsv($f, array_keys($row));
$first = false;
}
fputcsv($f, $row);
} // end while of inside loop
} // end while of 1st SQL query
However whilst I belive my idea is solid, I'm struggling to put it all together and looking for a little help.
Thanks
I have adapted the info from this site but instead of creating a csv file, it is only displaying the info in the command screen it is being executed in. I have tried entering $fileName = 'C:\Users\dmcgettigan\Desktop\mysql-export.csv'; and just the filename but I do not have a file being generated. Thank you in advance for your help, I am trying to teach myself php, and mysql!
Updated: added code
My Code:
<?php
//Our MySQL connection details.
$host = 'mysql_server';
$user = 'user';
$password = 'password';
$database = 'database';
//Connect to MySQL using PDO.
$pdo = new PDO("mysql:host=$host;dbname=$database", $user, $password);
//Create our SQL query.
$sql = "SELECT
a.InvoiceNumber, a.partnumber, a.Quantity, b.Discount, date
FROM
data a,
mars b
WHERE
a.PartNumber = b.partnumber
AND date >= '2018-09-28'
AND mfg = 'gk'
AND discount <> '0.00'
AND CustomerNumber IN ('Z5447520' , 'Z3715177', 'Z1234444', 'Z5425966')
AND Quantity > '0'";
//Prepare our SQL query.
$statement = $pdo->prepare($sql);
//Executre our SQL query.
$statement->execute();
//Fetch all of the rows from our MySQL table.
$rows = $statement->fetchAll(PDO::FETCH_ASSOC);
//Get the column names.
$columnNames = array();
if(!empty($rows)){
//We only need to loop through the first row of our result
//in order to collate the column names.
$firstRow = $rows[0];
foreach($firstRow as $colName => $val){
$columnNames[] = $colName;
}
}
//Setup the filename that our CSV will have when it is downloaded.
$fileName = 'mysql-export.csv';
//Set the Content-Type and Content-Disposition headers to force the download.
header('Content-Type: application/excel');
header('Content-Disposition: attachment; filename="' . $fileName . '"');
//Open up a file pointer
$fp = fopen('php://output', 'w');
//Start off by writing the column names to the file.
fputcsv($fp, $columnNames);
//Then, loop through the rows and write them to the CSV file.
foreach ($rows as $row) {
fputcsv($fp, $row);
}
//Close the file pointer.
fclose($fp);
$fp = fopen('php://output', 'w'); this specific line should be changed to $fp = fopen($filename, 'w'); because as is you are using the output as the file
This is my code to generate csv file.When I click php button to generate Csv file,which is filled withthe contents based on the category column from the database.But my problem here is when the contents are getting populated twice in the csv file as shown below.Please help to out where i have to modify the code so that i can get only one time populated content as shown below as expected.Thanks in advance.

not expected csv file with twice populated data:
var Login_Hits= [[1427826600000,1427826600000,8763,8763
]]
Expected csv file as per highcharts format:
var Login_Hits= [[1427826600000,8763
]]
Try to debug it...
it will be easier than seeing typo or so...
it looks like the tmp file is already corrupted...
try to display the $row variable and the $query...
the problem may come from here...
In while loop I have used mysql_fetch_assoc instead of mysql_fetch_array at both the functions
while($row = mysql_fetch_assoc($query))
{
fputcsv($fp, $row);
}
The content is not repeating twice in the Csv file.This works try it!
Right now I am inserting blob files into a database. I have read up on the update syntax for mysql I can not figure out how to modify my code to update a row with the BLOB instead of inserting a new row with the BLOB. Could someone help me with this?
Here is my code:
<?php
// Create MySQL login values and
// set them to your login information.
$username = "root";
$password = "";
$host = "localhost";
$database = "test";
$tbl_name="members";
// Make the connect to MySQL or die
// and display an error.
$link = mysql_connect($host, $username, $password);
if (!$link) {
die('Could not connect: ' . mysql_error());
}
// Select your database
mysql_select_db ($database);
// Make sure the user actually
// selected and uploaded a file
if (isset($_FILES['image']) && $_FILES['image']['size'] > 0) {
// Temporary file name stored on the server
$tmpName = $_FILES['image']['tmp_name'];
// Read the file
$fp = fopen($tmpName, 'r');
$data = fread($fp, filesize($tmpName));
$data = addslashes($data);
fclose($fp);
// Create the query and insert
// into our database.
$query = "INSERT INTO members ";
$query .= "(image) VALUES ('$data')";
$results = mysql_query($query, $link);
// Print results
print "Thank you, your file has been uploaded.";
}
else {
print "No image selected/uploaded";
}
// Close our MySQL Link
mysql_close($link);
?>
1° You need to pass a referecence for what Data you are trying to update, like the Primary Key Id From Table.
2° Update SQL should be like it
$image = mysql_real_escape_string($unsafe_image);
$id = mysql_real_escape_string($unsafe_id);
$query = "UPDATE members SET image = '$data' WHERE id_image = $id";
$results = mysql_query($query, $link);
I am exporting a SQL Server table to a CSV using php (see code below). What I am needing help with is including the headers of the columns in the export. I can do this when I export from MySQL, but cannot figure it out with SQL Server. If anyone can point me in the right direction I would appreciate it.
<?php
// SQL Server connection string details.
$myServer = "server";
$myUser = "user";
$myPass = "password";
$myDB = "dbname";
// connection to the SQL Server
$dbhandle = mssql_connect($myServer, $myUser, $myPass)
or die("Couldn't connect to SQL Server on $myServer");
//select a database to work with
$selected = mssql_select_db($myDB, $dbhandle)
or die("Couldn't open database $myDB");
//declare the SQL statement that will query the database
$query = "SELECT col01, col02, col03, col04, col05, col06, col07 ";
$query .= "FROM table ";
$result = mssql_query($query, $dbhandle);
//Generate CSV file - Set as MSSQL_ASSOC as you don't need the numeric values.
while ($l = mssql_fetch_array($result, MSSQL_ASSOC)) {
foreach($l AS $key => $value){
//If the character " exists, then escape it, otherwise the csv file will be invalid.
$pos = strpos($value, '"');
if ($pos !== false) {
$value = str_replace('"', '\"', $value);
}
$out .= '"'.$value.'",';
}
$out .= "\n";
}
//free result set memory
mssql_free_result($result);
//close the connection
mssql_close($dbhandle);
// Output to browser with the CSV mime type
header("Content-type: text/x-csv");
header("Content-Disposition: attachment; filename=export.csv");
echo $out;
?>
Use http://php.net/manual/en/function.mssql-fetch-field.php , like this:
http://www.razorsql.com/articles/sqlserver_column_names_values.html
Adding col01, col02, col03, col04, col05, col06, col07 to the first line of your $out variable before iterating through you request results will solve your problem
out .="col01, col02, col03, col04, col05, col06, col07\n"
