Automating CSV conversion from iso-8859-2 to utf-8 - php

I have quite a few CSV files that are unfortunately encoded with iso-8859-2 (according to Brackets). I would like to iterate over these files with PHP and convert them.
I found https://csv.thephpleague.com/9.0/converter/charset/ but the way I can use the conversion function is uncertain to me.
Their example code
use League\Csv\CharsetConverter;
$csv = new SplFileObject('/path/to/french.csv', 'r');
$csv->setFlags(SplFileObject::READ_CSV | SplFileObject::SKIP_EMPTY);
$encoder = (new CharsetConverter())->inputEncoding('iso-8859-15');
$records = $encoder->convert($csv);
This is my code so far that is part of a form to upload one file and save the contents to the database for testing. It of course saves the text in the incorrect format.
$db = ConnectDB::getConnection('address_dtb');
$sql = " ... ";
$stmt = $db->prepare($sql);
$rowCount = 0;
$temp_name = $_FILES['adresscsv']['tmp_name'];
$file_handle = fopen($temp_name, 'r');
while (($items = fgetcsv($file_handle, 1000, ';')) !== FALSE) {
if($flag) { $flag = false; continue; }
$stmt->execute($items);
$rowCount++;
}
fclose($file_handle);
ConnectDB::closeConnection($db);
What is the correct way to use the PHP CSV library above to iterate over locally saved files in a for loop to automate the process?

I ended up using iconv as hinted.
$files = glob('address/*.csv');
foreach ($files as $csv) {
$file_data = file_get_contents($csv);
$utf8_file_data = iconv('Windows-1250', 'UTF-8', $file_data);
file_put_contents($csv, $utf8_file_data);
}

You do not have to use a library. There is a function in PHP that can do that iconv

Read a tabulator seperated csv with PHP

I'm not able to read a tabulator seperarated csv file (and yes, i know its csv and no tsv and the c is for tabulator...) with php and seperate it right. When i give out my imported Data with echo or readfile all the tabulators are replaced by a space and i can't use space as a sperator.
Actually i'm a bit confused that this problem is not very common when i use Google, so maybe i'm the problem...
The Problem exists with XAMPP v3.2.3 and PHP Version 7.3.5
$tempFile = fopen($tempFilePath, "r");
$uploadData = fread($tempFile, filesize($tempFilePath));
fclose($tempFile);
echo $uploadData;
$uploadData = str_replace('"','',$uploadData);
$uploadData = str_replace('\r\n','\n',$uploadData);
$uploadData = str_replace('\r','\n',$uploadData);
$uploadData = str_replace(';',',',$uploadData);
$uploadData = str_replace('\t',',',$uploadData); //Here i'm trying to replace the tabulator with a colon to work with it afterwards
When reading a CSV file in PHP, it is best to use the fgetcsv function. With it you can specify the deliminator of the file. The function will output a row of the file. Your deliminator should be "\t".
You should use fgetcsv function which already has functionality to read tsv.
Like this:
$uploadData = [];
if (($handle = fopen("test.csv", "r")) !== false) {
while (($data = fgetcsv($handle, 0, "\t")) !== false) {
$uploadData[] = $data;
}
fclose($handle);
}
If you want to convert tsv to csv you can use inverse function fputcsv:
$fh = fopen('file.csv');
foreach ($uploadData as $datum) {
fputcsv($fh, $datum);
}
fclose($fh);
If you want automatically detect csv delimiter maybe this article can help you.

Convert a CSV file to force encapsilation

My ideal fix would be a function that can take a CSV file that does not have forced encapsulation (no quotes around values if the value has no spaces or is just a number) and convert it into a CSV file that makes sure every field is encapsulated with double quotes.
<?php
$raw_file = BASE_DIR."pathto/csv.csv";
$fixed_file = BASE_DIR."pathto/fixed.csv";
convert_file($raw_file, $fixed_file);
//move on with life!!
?>
Thanks for you help!
Use fgetcsv to get the contents of your original csv file and fputcsv (using the fourth parameter) to build the encapsulated file.
For example, supposing your column separator is ; :
<?php
$raw_file = BASE_DIR."pathto/csv.csv";
$fixed_file = BASE_DIR."pathto/fixed.csv";
// Getting contents
$raw_handle = fopen($raw_file, 'r');
$contents = array();
while (($data = fgetcsv($raw_handle, 0, ';')) !== false) {
$contents[] = $data;
}
fclose($raw_handle);
// Putting contents
$fixed_handle = fopen($fixed_file, 'w');
foreach ($contents as $line) {
fputcsv($fixed_handle, $line, ';', '"');
}
fclose($fixed_handle);
//move on with life!!
?>

PHP Formatting A Column (dollar sign) In csv Upload Script

I have a script that uploads a csv file with 3 columns (phone, name, amount). The script removes any formatting on the phone, ie; ()- and puts the file on the server. The amount column in the file shows the amount like 125.00 and I need it to show $125.00. Any help would be much appreciated.
$file_destination = '/****/****/****/***/' . $file_name_new;
$contents = file_get_contents($file_tmp);
$contents = str_replace("(","",$contents);
$contents = str_replace(")","",$contents);
$contents = str_replace("-","",$contents);
file_put_contents($file_tmp, $contents);
if(move_uploaded_file($file_tmp, $file_destination)) {
Whether you want to reformat the values strictly for output or store the new formatted data in your CSV file, it's probably going to be more effective to use fgetcsv and fputcsv. Those functions are designed for properly reading in and writing out CSV formatted files.
Example
$rows = [];
if (($handle = fopen($file_tmp, "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
list($phone, $name, $amount) = $data;
$phone = str_replace(['(',')','-'], '', $phone);
$amount = sprintf('$%.2f', $amount);
// you can build a new array with the updated values
$rows[] = [$phone, $name, $amount];
// or output directly
echo "$phone | $name | $amount";
}
fclose($handle);
}
// if you want to save the destination with the updated information...
$fp = fopen($file_destination, 'w');
foreach ($rows as $fields) {
fputcsv($fp, $fields);
}
fclose($fp);

Php script to Import CSV with Arabic content

I have to build a script to import a CSV file, (With Arabic content in one coloumn).
I have been searching online and manage to convert my CSV file to UTF8
$filename = $_FILES["csv"]["tmp_name"];
$file = fopen($filename, "r");
$count = 0;
while (($emapData = fgetcsv($file, 10000, ",")) !== FALSE)
{
$count++;
if($count>1){
// tried to convert using below
$string_decoded = iconv("windows-1256", "utf-8", $emapData[2]);
// convert code above
$sql = "INSERT into `$table` (SurahNo,AyatNo,Ayat) values ('$emapData[0]','$emapData[1]','$string_decoded')";
echo $sql;
mysql_query($sql);
}
}
I tried to convert using iconv but still getting garbage content imported in mysql.
Imported content look like this

Can share my CSV file if you wish.
Need help, spend hours searching.

How to generically open a file in php

I've looked for questions on this topic, but failed to get what I'm looking for. This is for C++, I need similar for PHP. This is for including php files, I just want to read a CSV file.
I have this:
if(file_exists("data.csv")){
echo "CSV file found";
$csv_data = file_get_contents("data.csv");
$lines = explode("\n", trim($csv_data));
$array = array();
foreach ($lines as $line){
$array[] = str_getcsv($line);
}else {echo "File not found";}
But I want to NOT specify the file name - i.e. generically load/read/open the file.
Is there any simple why of doing that? Doesn't make sense, but I was told to not have anything hard coded in my PHP script.
Thanks in advance.
use fgetcsv
if(file_exists("data.csv")){
echo "CSV file found";
$handle = fopen("data.csv", "r");
if(!$handle) die("Could not open file!");
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
$row++;
for ($c=0; $c < $num; $c++) {
echo $data[$c] . "<br />\n";
}
}
fclose($handle);
}else {echo "File not found";}
If you may not have anything hard coded in your script, you need to put those hardcoded things into some sort of external config file. You will have to hardcode the name of that config file into your bootstrap or whatever comes first in your application. Once the config is loaded, make the configuration data available in the places where it is needed. Not hardcoding configuration data into your code will allow you to create more reusable components and code, e.g. CSV Reader that can read any CSV file instead of a CSV Reader that can only read that one particular CSV file hardcoded into it.
Example:
// config.php
<?php
return array(
'csvFile' => '/path/to/file.csv',
…
);
// bootstrap.php
<?php
$config = include '/path/to/config.php';
…
// someFile.php
<?php
include '/path/to/bootstrap.php';
$file = new SplFileObject($config['csvFile']);
$file->setFlags(SplFileObject::READ_CSV);
foreach ($file as $row) {
// Do something with values
}
Put your code into a function...
function open_file($file_name)
{
if (!file_exists($file_name))
{
return false;
}
$csv_data = file_get_contents($file_name);
$lines = explode("\n", trim($csv_data));
$array = array();
foreach ($lines as $line)
{
$array[] = str_getcsv($line);
}
return $array;
}
