EDIT: I changed "echo($row)" to "print_r($row)" and now the csv that's being downloaded has each array in parenthesis with all the data mentioned, but how do I customize the way it all can be printed?
Right now, it's printing:
Array (
[id]=>1
[firstname]=>"Timmy"
)
Array (
....
(where each line is the next row in the excel spreadsheet)
How would I make this output so that each record has it's own row? for example the first column in excel would be id, then the second would be firstname, with each record it's own row?
I've got a link in my main.php:
<a class="btn" href="export.php">Export</a>
Then here's my export.php file:
<?php
//open database connection
try {
$db = new PDO('mysql:host=localhost;dbname=DBNAME;charset=utf8',
'DBUSER',
'DBPASS');
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_SILENT);
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
}
catch(PDOException $ex) {
echo "did not connect...";
}
header('Content-Type: text/csv');
header('Content-Disposition: attachment;filename=exported-data.csv');
$sql = "SELECT * FROM table_name;";
$sth = $db->prepare($sql);
$sth->execute();
$filename = date('d.m.Y').'.csv';
$data = fopen($filename, 'w');
while ($row = $sth->fetch(PDO::FETCH_ASSOC)) {
fputcsv($data, $row);
print_r($row);
}
echo "\r\n";
fclose($data);
?>
In order to get an associative array to be placed properly into your file you'll need to parse the array and then put the line in the file:
while ($row = $sth->fetch(PDO::FETCH_ASSOC)) {
$csv = implode(',', $row) . "\n";
fwrite($data, $csv);
print_r($csv);
}
I assume your output should be a csv file with the date as a file name, am I correct?
Could you try this:
UPDATED CODE
<?php
//open database connection
try {
$db = new PDO('mysql:host=localhost;dbname=DBNAME;charset=utf8',
'DBUSER',
'DBPASS');
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_SILENT);
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
}
catch(PDOException $ex) {
echo "did not connect...";
}
$sql = "SELECT * FROM table_name";
$sth = $db->prepare($sql);
$sth->execute();
$filename = date('d.m.Y').'.csv';
$data = fopen($filename, 'w');
while ($row = $sth->fetch(PDO::FETCH_ASSOC)) {
fputcsv($data, $row);
}
fclose($data);
?>
The code will break because the "." is in the wrong place.
$filename = date('d.m.Y').'.csv'; is not the same as $filename = 'date('d.m.Y').'.csv';
#NoReceipt4Panda: I can not comment so Code is updated.
You should be using $sth = $db->prepare($sql); not $sth = $conn->prepare($sql);.
You don't have a variable with the name $conn.
My goal is to create a MySQL table containing data from my CSV file.
I know how to create a MySQL table and how to load data from excel in it.
But the problem is:
I have a large CSV file containing long column names (questions labels for example "Q27 : Are you happy with the after sales service?") so it would be boring to create a MySQL table by copying all column names(almost 35) and add 'VARCHAR(100) NOT NULL'.
That's why I would like to write a small php script to create a MySQL table by getting the first row of my file, and then fill it with the rest of the csv file data.
For now, my script looks like this :
<?php
$host = 'localhost';
$user = 'root';
$pass = '';
$database = 'test';
$db = #mysql_connect($host, $user, $pass) or die('mysql connection pb');
#mysql_select_db($database) or die('database selection pb');
/********************************************************************************/
// Parameters: filename.csv table_name
$argv = $_SERVER['argv'];
if($argv[1]) { $file = $argv[1]; }
else {
echo "Please provide a file name\n"; exit;
}
if($argv[2]) {
$table = $argv[2];
}
else {
echo "Please provide a table name\n";
$table = pathinfo($file);
$table = $table['filename'];
}
/**************************************************************************** ****/
// Get the first row to create the column headings
$fp = fopen($file, 'r');
$frow = fgetcsv($fp,";");
$columns=false;
print_r($frow);
foreach($frow as $column) {
if($columns) $columns .= ', ';
$columns .= "`$column` VARCHAR(250) NOT NULL";
}
$create = "create table if not exists $table ($columns);";
#mysql_query($create, $db) or die('table creation pb');
/**************************************************************************** ****/
// Import the data into the newly created table.
$file = addslashes(realpath(dirname(__FILE__)).'\\'.$file);
$q = "load data infile '$file' into table $table fields terminated by ',' ignore 1 lines";
#mysql_query($q, $db);
?>
And when i run in command line : php myscript.php csvfile.csv mytable, it appears that the problem is in the table creation query.
And on top of that the column names are not well identified even though they are separated by ";" in the csv.
As mentioned refrain from using mysql_ functions which as of PHP 7 (current version) this extension is no longer available. Use either mysqli or PDO.
Below is a PDO example with try/catch (more informative than die()). Also, the csv read is handled slightly different and its concatenation in SQL create table string.
<?php
$host="localhost";
$username="root";
$password="password";
$database="test"
// Parameters: filename.csv table_name
$argv = $_SERVER['argv'];
if($argv[1]) {
$file = $argv[1];
} else {
echo "Please provide a file name\n";
exit;
}
if($argv[2]) {
$table = $argv[2];
} else {
echo "Please provide a table name\n";
$table = pathinfo($file);
$table = $table['filename'];
}
// Read in only first row of CSV file
$handle = fopen($file, "r");
$row = 1;
$columns = [];
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE AND $row==1) {
$columns = $data;
$row++;
}
//SQL string commands
$createSQL = "CREATE TABLE IF NOT EXISTS $table
(".implode(" VARCHAR(255) NOT NULL, ", $columns). "
VARCHAR(255) NOT NULL);";
$file = addslashes(realpath(dirname(__FILE__)).'\\'.$file);
$loadSQL = "LOAD DATA INFILE '$file'
INTO TABLE $table
FIELDS TERMINATED BY ','
IGNORE 1 LINES";
// Open database connection
try {
$dbh = new PDO("mysql:host=$host;dbname=$database",$username,$password);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// Execute queries
$S1TH = $dbh->query($createSQL);
$S2TH = $dbh->query($loadSQL);
}
catch(PDOException $e) {
echo $e->getMessage();
}
# Close database connection
$dbh = null;
?>
I'm using this script for importing a csv file to mysql database.
How can i display a progress bar for importing a csv file to db using jquery and php ?
I don't need te actual code, just some infos.
Thanks in advance.
if ( $request->get( $_POST["action"] ) == "import" ) {
$file = $upload->file_upload( "import", "media/import" );
if ( file_exists( DIR_UPLOAD_PHOTO . "/media/import/" . $file ) ) {
$file = DIR_UPLOAD_PHOTO . "/media/import/" . $file;
try {
$dbh = new PDO("mysql:host=".HOST."; dbname=".DATABASE, USER, PASSWORD);
}
catch(PDOException $e) {
echo $e->getMessage();
}
$handle = fopen( $file, "r" );
$delimiter = '|';
$dbh->beginTransaction();
$stmt = $dbh->prepare("INSERT INTO products SET title = :title, price = :price
ON DUPLICATE KEY UPDATE
title = :title, price = :price"
);
fgets($handle);
$rows = count(file($file));
while ($line = fgetcsv($handle, 1000, $delimiter)) {
$line = array_map('trim', $line);
$stmt->bindParam(':title', $line[0], PDO::PARAM_STR);
$stmt->bindParam(':price', $line[1], PDO::PARAM_STR);
$stmt->execute();
}
$dbh->commit();
fclose($handle);
$dbh = null;
}
}
At last in MariaDB you get some Status-Information this way (don't know if it works in MySQL as well):
Fork the INSERT INTO ... Statement in an other process
and run it.
Use SHOW PROCESSLIST in your main thread to get the Status of the INSERT Statement.
I'm trying to import a .sql file through PHP code. However, my code shows this error:
There was an error during import. Please make sure the import file is saved in the same folder as this script and check your values:
MySQL Database Name: test
MySQL User Name: root
MySQL Password: NOTSHOWN
MySQL Host Name: localhost
MySQL Import Filename: dbbackupmember.sql
And this is my code:
<?php
//ENTER THE RELEVANT INFO BELOW
$mysqlDatabaseName ='test';
$mysqlUserName ='root';
$mysqlPassword ='';
$mysqlHostName ='localhost';
$mysqlImportFilename ='dbbackupmember.sql';
//DONT EDIT BELOW THIS LINE
//Export the database and output the status to the page
$command='mysql -h' .$mysqlHostName .' -u' .$mysqlUserName .' -p' .$mysqlPassword .' ' .$mysqlDatabaseName .' < ' .$mysqlImportFilename;
exec($command,$output=array(),$worked);
switch($worked){
case 0:
echo 'Import file <b>' .$mysqlImportFilename .'</b> successfully imported to database <b>' .$mysqlDatabaseName .'</b>';
break;
case 1:
echo 'There was an error during import.

break;
}
?>
What am I doing wrong? The SQL file is in the same directory.

This is working for me
You can use the mysqli multi_query function as below:
$sql = file_get_contents('mysqldump.sql');
$mysqli = new mysqli("localhost", "root", "pass", "testdb");
/* execute multi query */
$mysqli->multi_query($sql);

the answer from Raj is useful, but (because of file($filename))
it will fail if your mysql-dump not fits in memory
If you are on shared hosting and there are limitations like 30 MB and 12s Script runtime and you have to restore a x00MB mysql dump, you can use this script:
it will walk the dumpfile query for query, if the script execution deadline is near, it saves the current fileposition in a tmp file and a automatic browser reload will continue this process again and again ...
If an error occurs, the reload will stop and an the error is shown ...
if you comeback from lunch your db will be restored ;-)
the noLimitDumpRestore.php:
// your config
$filename = 'yourGigaByteDump.sql';
$dbHost = 'localhost';

Grain Script is superb and save my day. Meanwhile mysql is depreciated and I rewrote Grain answer using PDO.
$server = 'localhost';
$username = 'root';

$database = 'sample_db';
/* PDO connection start */
$conn = new PDO("mysql:host=$server; dbname=$database", $username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$conn->exec("SET CHARACTER SET utf8");
/* PDO connection end */

$filename = 'yourFile.sql';
$maxRuntime = 8; // less then your max script execution limit
$deadline = time()+$maxRuntime;
$progressFilename = $filename.'_filepointer'; // tmp file for progress
$errorFilename = $filename.'_error'; // tmp file for erro
($fp = fopen($filename, 'r')) OR die('failed to open file:'.$filename);

I have Test your code, this error shows when you already have the DB imported or with some tables with the same name, also the Array error that shows is because you add in in the exec parenthesis, here is the fixed version:
<?php
//ENTER THE RELEVANT INFO BELOW
$mysqlDatabaseName ='test';
$mysqlUserName ='root';
$mysqlPassword ='';
$mysqlHostName ='localhost';
$mysqlImportFilename ='dbbackupmember.sql';
//DONT EDIT BELOW THIS LINE
//Export the database and output the status to the page
$command='mysql -h' .$mysqlHostName .' -u' .$mysqlUserName .' -p' .$mysqlPassword .' ' .$mysqlDatabaseName .' < ' .$mysqlImportFilename;
$output=array();
exec($command,$output,$worked);
switch($worked){
case 0:
echo 'Import file <b>' .$mysqlImportFilename .'</b> successfully imported to database <b>' .$mysqlDatabaseName .'</b>';
break;
case 1:
echo 'There was an error during import.';
break;
}
?>
If you need a User Interface and if you want to use PDO
Here's a simple solution
<form method="post" enctype="multipart/form-data">
<input type="text" name="db" placeholder="Databasename" />
<input type="file" name="file">
<input type="submit" name="submit" value="submit">
</form>
<?php
if(isset($_POST['submit'])){
$query = file_get_contents($_FILES["file"]["name"]);
$dbname = $_POST['db'];
$con = new PDO("mysql:host=localhost;dbname=$dbname","root","");
$stmt = $con->prepare($query);
if($stmt->execute()){
echo "Successfully imported to the $dbname.";
}
}
?>

I'm trying to import CSV data into a MySQL database using the fgetcsv function.
if(isset($_POST['submit'])) {
$fname = $_FILES['sel_file']['name'];
$var = 'Invalid File';
$chk_ext = explode(".",$fname);
if(strtolower($chk_ext[1]) == "csv") {
$filename = $_FILES['sel_file']['tmp_name'];
$handle = fopen($filename, "r");
$res = mysql_query("SELECT * FROM vpireport");
$rows = mysql_num_rows($res);
if($rows>=0) {
mysql_query("DELETE FROM vpireport") or die(mysql_error());
for($i =1;($data = fgetcsv($handle, 10000, ",")) !== FALSE; $i++) {
if($i==1)
continue;
$sql = "INSERT into vpireport
(item_code,
company_id,
purchase,
purchase_value)
values
(".$data[0].",
".$data[1].",
".$data[2].",
".$data[3].")";
//echo "$sql";
mysql_query($sql) or die(mysql_error());
}
}
fclose($handle);
?>
<script language="javascript">
alert("Successfully Imported!");
</script>
<?
}
The problem is it gets stuck in between the import process and displays the following error:
You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near 'S',0,0)' at line 1
The file is imported only partially each time. Only between 200-300 lines out of a 10000 line file are imported.
Here is the DDL of my table:
create table vpireport (
id int not null auto_increment,
item_code int,
company_id int,
purchase double,
primary key(id),
foreign key(company_id) references users(userid)
);
I haven't been able to find the problem so far, any help appreciated. Thanks.
You probably need to escape quotes, which you could accomplish using PDO and prepared statements.
I've skipped most of your code in the example for brevity and just focused on the for loop.
<?php
// Use PDO to connect to the DB
$dsn = 'mysql:dbname=YOUR_DB;host=localhost';
$user = 'DB_USERNAME';
$password = 'DB_PASSWORD';
try {
$dbh = new PDO($dsn, $user, $password);
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}
for($i =1;($data = fgetcsv($handle, 10000, ",")) !== FALSE; $i++) {
// The query uses placeholders for data
$sql = "INSERT INTO vpireport
(item_code,company_id,purchase,purchase_value)
VALUES
(:item_code,:company_id,:purchase,:purchase_value)";
$sth = $dbh->prepare($sql);
// The data is bound to the placeholders
$sth->bindParam(':item_code', $data[0]);
$sth->bindParam(':company_id', $data[1]);
$sth->bindParam(':purchase', $data[2]);
$sth->bindParam(':purhcase_value', $data[3]);
// The row is actually inserted here
$sth->execute();
$sth->closeCursor();
}
That won't get rid of any problem characters, though, so you may want to look at some kind of data sanitization if that poses a problem.
uncomment the //echo "$sql"; and look what is the last query (with error) - it may be that the csv data contains strange characters or the query is cut off.
BTW: you can also import csv file by mysql:
http://dev.mysql.com/doc/refman/5.1/en/load-data.html
$row = 1;
if (($handle = fopen("albums.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ',','"')) !== FALSE) {
if($row!=1){
$num = count($data);
$albumIndex=0;
//Insert into tbl_albums
$sqlAlbums="INSERT INTO tbl_albums(albumName) VALUES ('".$data[$albumIndex]."')";
$resultAlbums=mysql_query($sqlAlbums);
}
}
$row++;
}
}
fclose($handle);
