“How to export other next file‘ after 2000 rows data - php

I am using PHP for export CSV file this is working, but i export 2000 or greater rows how to create automatic next CSV file.
How to Move other file on after 2000 rows?
<?php
header('Content-type: application/csv');
header('Content-Disposition: attachment; filename = records.csv');
echo $header = "Name";
echo "\r\n";
$sql = mysql_query(“Select * from table”);
while ($getData = mysql_fetch_assoc($sql)) {
echo '"'.$name.'"';
echo "\r\n";
}
exit;
?>

You can use array_chunk function to keep the records of 2000 and export them in csv.
For example
$rowData = [
[1,2,3],
[11,21,31],
[21,22,32],
[31,42,73],
[111,222,333]
];
foreach(array_chunk($rowData, 2) as $key => $records){
$file_name = 'export_data_'.$key.'.csv';
writeToCsv($file_name,$records);
}
//funtion to export data to csv
function writeToCsv($fileName, $rowData){
$fp = fopen($fileName, 'w');
foreach ($rowData as $fields) {
fputcsv($fp, $fields);
}
fclose($fp);
}
In your case use array_chunk($rowData, 2000)

<?php
$rowLimit = 2000;
$fileIndex = 0;
$i = 1;
$handle = null;
$fileList = array();
$timestampFolder = strtotime("now").'/';
mkdir($timestampFolder);
$sql = mysql_query("Select * from table");
while ($getData = mysql_fetch_assoc($sql)) {
if( ($i%$rowLimit) == 1) {
$fileIndex+=1;
if(!is_null($handle)) {
fclose($handle);
}
$fileName = "records".$fileIndex.".csv";
$handle = fopen($timestampFolder.$fileName, "a");
$fileList[] = $fileName;
}
fputcsv($handle, $getData);
$i++;
}
foreach($fileList as $file) {
echo ''.$file.'<br>';
}

How to write and save CSV file to server in PHP?

I am trying to create a new CSV file using PHP and upload or move it to a new part of the server but the spreadsheet it returns is a spreadsheet that has only the first cell in the first row with a value of either 404 or 1. What am I doing wrong?
My code is attached below.
// genrate new general spreadsheet
$filepath = substr($file_path, 1);
$data = load_csv_file($filepath);
header('Content-type: text/csv');
header('Content-Disposition: attachment; filename="file-saved.csv"');
$fp = fopen('php://output', 'wb');
foreach ($data as $row) {
$output = fputcsv($fp, $row);
}
$filename = "file-saved.csv";
file_put_contents( $filename, $output);
fclose($fp);
The $data variable is an array of values from another CSV file.
$output = [];
foreach($data as $row) {
$output[] = ..
}
...
error_reporting(0);
$file_n = public_path('/csv_file/product_details.csv');
$infoPath = pathinfo($file_n);
if($infoPath['extension'] == 'csv'){
$file = fopen($file_n, "r");
$i = 0;
$all_data = array();
while ( ($filedata = fgetcsv($file, null, "|")) !==FALSE) {
$num = count($filedata );
for ($c=0; $c < $num; $c++) {
$all_data[$i][] = $filedata [$c];
}
$i++;
}
fclose($file);
foreach($all_data as $importData){
$insertData = array(
"article_number"=>$importData[0],
"article_name"=>$importData[1],
"article_description"=>$importData[2],
"article_price"=>$importData[3],
"article_manufacturer"=>$importData[6],
"article_productgroupkey"=>$importData[7],
"article_productgroup"=>$importData[8],
"article_ean"=>$importData[9],
"article_hbnr"=>$importData[10],
"article_shippingcosttext"=>$importData[11],
"article_amount"=>$importData[12],
"article_paymentinadvance"=>$importData[13],
"article_maxdeliveryamount"=>$importData[14],
"article_energyefficiencyclass"=>$importData[15]
);
insertData($insertData);
}
}else{
echo "Invalid file extension.";
}
function insertData($data){
if($article_number->count() == 0){
//write your insert query here for $data
}elseif($article_number->count() > 0){
//article_number already present then update the table.UPDATE QUERY
}
}

PHP Split CSV file and update to Database doesn't work

I would like to split a very large CSV file (20 000 lines) to be able to put everything in my MySQL database (after I use cronjob for load the php file every hours).
So I have found code to split my file :
$inputFile = 'Shipping.csv';
$outputFile = 'output';
$splitSize = 1000;
$in = fopen($inputFile, 'r');
$rowCount = 0;
$fileCount = 1;
while (!feof($in)) {
if (($rowCount % $splitSize) == 0) {
if ($rowCount > 0) {
fclose($out);
}
$out = fopen($outputFile . $fileCount++ . '.csv', 'w');
}
$data = fgetcsv($in);
if ($data)
fputcsv($out, $data);
$rowCount++;
}
fclose($out);
I have tried to do this but they don't work :
require_once dirname(__DIR__).'/pdo.php';
$inputFile = 'Shipping.csv';
$outputFile = 'output';
$splitSize = 1000;
//open uploaded csv file with read only mode
$in = fopen($inputFile, 'r');
//skip first line
fgetcsv($in);
$rowCount = 0;
$fileCount = 1;
while (!feof($in)) {
if (($rowCount % $splitSize) == 0) {
if ($rowCount > 0) {
fclose($out);
}
$out = fopen($outputFile . $fileCount++ . '.csv', 'w');
}
$data = fgetcsv($in);
if ($data){
fputcsv($out, $data);
}
while(($line = fgetcsv($out)) !== FALSE){
//check whether member already exists in database with same email
$prevQuery = "SELECT id FROM shipbp WHERE license = '".$line[1]."'";
$prevResult = $bdd->query($prevQuery);
if($prevResult->rowCount() > 0)
{
$bdd->query("UPDATE shipbp SET license = '".$line[0]."'");
}
else{
$bdd->query("INSERT INTO shipbp (license) VALUES ('".$line[0]."')");
}
}
$rowCount++;
}
fclose($out);
CSV file look like :
P135460,002,00003,250,AS44563,0.35,,Blabla,17/3/2017 00:00:00,SB,Blabla
How I can do ?
Thank you for your help

Save query results to .csv with PHP

I have the following query running and I am looking at the best way to export the data to a .csv or .xls file.
<?php
$channels = ee()->db->select('channel_titles.entry_id, channel_titles.title, channel_data.field_id_164')
->from('channel_titles')
->join('channel_data', 'channel_titles.entry_id = channel_data.entry_id')
->where(array(
'channel_titles.channel_id' => '12',
))
->or_where(array(
'channel_titles.channel_id' => '31',
))
->get();
if ($channels->num_rows() > 0)
{
$i = 0;
foreach($channels->result_array() as $row)
{
$i++;
echo $row['field_id_164'].",".$row['title']."<br />\n";
}
echo $i;
}
?>
I have tried a few methods but cannot seem to figure out the best option.
The classic echo explode(',',$col) etc way is fine, but you can also write directly to the csv file using php's built in functions.
$filename = 'test.csv';
$file = fopen($filename,"w");
if ($channels->num_rows() > 0) {
foreach($channels->result_array() as $key => $row) {
if ($key==0) fputcsv($file, array_keys((array)$row)); // write column headings, added extra brace
foreach ($row as $line) {
$line = (array) $line;
fputcsv($file, $line);
}
}
}
fclose($file);
edit:
If you want to download/view the file instantly you have to set the headers.
$filename = 'test.csv';
header('Content-type: application/csv');
header('Content-Disposition: attachment; filename=' . $filename);
header("Content-Transfer-Encoding: UTF-8");
$file = fopen('php://output', 'a');
if ($channels->num_rows() > 0) {
foreach($channels->result_array() as $key => $row) {
if ($key==0) fputcsv($file, array_keys((array)$row)); // write column headings, added extra brace
foreach ($row as $line) {
$line = (array) $line;
fputcsv($file, $line);
}
}
}
fclose($file);

insert a 2d array into a csv file in php

I'm trying to insert the 2d array into a csv file
here is my code below
<?php
$cars = array( array("Volvo",100,96), array("BMW",60,59), array("Toyota",110,100));
$fp = fopen('file.xls', 'w');
foreach ($cars as $fields) {
fputcsv($fp, $fields);
}
fclose($fp);
?>
but the values are inserted in single row in csv file.
any ideas
EDIT 1:
This version saves it to file without prompting to save and outputs in a table with a slight border. The border in the table is not written to file, it only outputs to screen.
<?php
$fp = fopen('file.xls', 'w');
$cars = array( array(Volvo,100,96), array(BMW,60,59), array(Toyota,110,100));
$titleArray = array_keys($cars[0]);
$delimiter = "\t";
$filename="file.xls";
//Loop through each subarray, which are our data sets
foreach ($cars as $subArrayKey => $subArray) {
//Separate each datapoint in the row with the delimiter
$dataRowString = implode($delimiter, $subArray);
// print $dataRowString . "\r\n"; // prints output to screen
fwrite($fp, $dataRowString . "\r\n");
} // keep this always end of routine
// start of cell formatting
$row = 1;
if (($handle = fopen("file.xls", "r")) !== FALSE) {
echo '<table border="1" cellspacing="0" cellpadding="3">';
while (($data = fgetcsv($handle, 1000, '\t')) !== FALSE) {
$num = count($data);
if ($row == 1) {
echo '<thead><tr>';
}else{
echo '<tr>';
}
for ($c=0; $c < $num; $c++) {
//echo $data[$c] . "<br />\n";
if(empty($data[$c])) {
$value = " ";
}else{
$value = $data[$c];
}
if ($row == 1) {
echo '<th>'.$value.'</th>';
}else{
echo '<td align="center">'.$value.'</td>';
}
}
if ($row == 1) {
echo '</tr></thead><tbody>';
}else{
echo '</tr>';
}
$row++;
}
echo '</tbody></table>';
fclose($handle);
}
?>
EDIT 2:
This version will process the data then prompt to save the file.
Output:
Volvo 100 96
BMW 60 59
Toyota 110 100
PHP code:
<?php
$cars = array( array(Volvo,100,96), array(BMW,60,59), array(Toyota,110,100));
$titleArray = array_keys($cars[0]);
$delimiter = "\t";
$filename="file.xls";
//Send headers
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=$filename");
header("Pragma: no-cache");
header("Expires: 0");
//Loop through each subarray, which are our data sets
foreach ($cars as $subArrayKey => $subArray) {
//Separate each datapoint in the row with the delimiter
$dataRowString = implode($delimiter, $subArray);
print $dataRowString . "\r\n";
}
?>
1st version:
Output will be:
Volvo
100
96
BMW
60
59
Toyota
110
100
If this is the desired result, then this is the code to accomplish this:
<?php
$cars = array( array(Volvo,100,96), array(BMW,60,59), array(Toyota,110,100));
$fp = fopen('file.xls', 'w');
foreach ($cars as $fields) {
fputcsv($fp, $fields, "\n");
}
fclose($fp);
?>
You need to seperate the contents with comma to write in seperate rows.
$export_arr =$_POST['dataString'];
$fp = fopen('file.xls', 'w');
foreach ($export_arr as $fields) {
fputcsv($fp, $fields,",");
}
fclose($fp);

Writing to multiple (splitting) CSV files with PHP

I'm using a simple function to write write arrays to a CSV-file, which look like this:
function writeToCSV($array) {
$fp = fopen('programmes.csv', 'a');
fputcsv($fp, $array);
fclose($fp);
}
Simple as a pie. However, is there anyway to know what line-number the pointer is at? Because I want to be able to after 1000 lines to begin writing to a new file. Why? Because I need to be able to import them to a database later with some memory constraints, and to parse a CSV-file with 15000 lines is a no-no.
function writeToCSV($array) {
$i = 1;
$j = 1;
$fp = fopen('programmes' . $j . '.csv', 'a');
foreach($array as $fields) {
if ($i % 1000 == 0) {
fclose($fp);
$fp = fopen('programmes' . $j . '.csv', 'a');
$j = $j + 1;
}
fputcsv($fp, $fields);
$i = $i + 1;
}
fclose($fp);
}
Try this:
count(file('programmes.csv'));
This will give you the number of lines in a file.
I haven't tried if this works, but i would do something like this:
<?php
function writeToCSV($array) {
// count lines in the current file
$linecount = 0;
$fh = fopen('programmes.csv','rb') or die("ERROR OPENING DATA");
while (fgets($fh) !== false) $linecount++;
fclose($fh);
$aSize = sizeof($array);
if (($linecount + $aSize) > 1000) {
// split array
$limit = 1000 - $linecount;
$a = array_slice($array, 0, $limit);
$b = array_slice($array, $limit);
// write into first file
$fp = fopen('programmes.csv', 'a');
foreach($a as $field) fputcsv($fp, $field);
fclose($fp);
// write into second file
$fp = fopen('programmes2.csv', 'a');
foreach($b as $field) fputcsv($fp, $field);
fclose($fp);
} else {
$fp = fopen('programmes.csv', 'a');
$idx = 0;
while ($linecount < 1000) {
// fill the file to the 1000 lines
fputcsv($fp, $array[$idx]);
++$linecount;
++$idx;
}
fclose($fp);
if ($idx != $aSize) {
// create new file
$fp = fopen('programmes.csv', 'a');
while ($idx< $aSize) {
// fill the file to the 1000 lines
fputcsv($fp, $array[$idx]);
++$idx;
}
fclose($fp);
}
}
}
?>
