Usage

search by keyword

     $temp = new TempFileHandler();
     $csv = new CsvFileHandler($temp);

     $findByKeyword = $csv->searchInCsvFile("movies.csv","Twilight","Film");

Search and return array

$temp = new TempFileHandler();
$csv = new CsvFileHandler($temp);

$findByKeyword = $csv->searchInCsvFile("movies.csv","Twilight","Film",FileHandler::ARRAY_FORMAT);

// output

[
    [Film] => Twilight

    [Year] => 2008


 ];

Write multiple files simultaneously

$fileHandler = new FileHandler();

$fileHandler->open('file.txt');

$fileHandler->open('php://stdout');

$fileHandler->write(data: "hello world");

$fileHandler->close();

Converting file to an array

$temp = new TempFileHandler();
$csv = new CsvFileHandler($temp);

$findByKeyword = $csv->toArray("movies.csv");
// output
$data[0] = [
            'Film' => 'Zack and Miri Make a Porno',
            'Genre' => 'Romance',
            'Lead Studio' => 'The Weinstein Company',

            'Worldwide Gross' => '$41.94 ',
            'Year' => '2008'

        ];

Find and replace in csv file

$temp = new TempFileHandler();
$csv = new CsvFileHandler($temp);

$findByKeyword = $csv->findAndReplaceInCsv("movies.csv","Twilight","Inception");

Find and replace a specific keyword in a particular column of a CSV file

$temp = new TempFileHandler();
$csv = new CsvFileHandler($temp);

$findByKeyword = $csv->findAndReplaceInCsv("movies.csv","Inception","Twilight",column: "Film");

Converting file to json format

$temp = new TempFileHandler();
$csv = new CsvFileHandler($temp);

$findByKeyword = $csv->toJson("movies.csv");

//output
[{"Film":"Zack and Miri Make a Porno","Genre":"Romance","Lead Studio":"The Weinstein Company","Audience score %":"70","Profitability":"1.747541667","Rotten Tomatoes %":"64","Worldwide Gross":"$41.94 ","Year":"2008"},{"Film":"Youth in Revolt","Genre":"Comedy","Lead Studio":"The Weinstein Company","Audience score %":"52","Profitability":"1.09","Rotten Tomatoes %":"68","Worldwide Gross":"$19.62 ","Year":"2010"},{"Film":"Twilight","Genre":"Romance","Lead Studio":"Independent","Audience score %":"68","Profitability":"6.383363636","Rotten Tomatoes %":"26","Worldwide Gross":"$702.17 ","Year":"2011"}]

Encrypt and decrypt files

$secret = getenv('SECRET_KEY');

$fileEncryptor = new FileEncryptor('movie.csv', $secret);
$fileEncryptor->encryptFile();
$fileEncryptor->decryptFile();

Stream and save content from url to file

 $url = "https://gist.github.com/rcsofttech85/629b37d483c4796db7bdcb3704067631#file-gistfile1-txt";
 $stream = new Stream($url, "outputFile.html");
 $stream->startStreaming();

File compression and decompression

        $testFile = 'movie.csv';
        $compressedZipFilename = 'compressed.zip';

        $this->fileHandler->compress($testFile, $compressedZipFilename);



        $compressedZipFilename = 'compressed.zip';
        $extractPath = 'extracted_contents';

        $this->fileHandler->decompress($compressedZipFilename, $extractPath);

File Difference

vendor/bin/file-diff oldFile newFile

File Integrity Check

$fileHasher = new FileHashChecker();

$fileHasher->hashFile(); 

$fileHasher->verifyHash($hashListFile);

View csv in terminal
