Php xlsx file reader

Обзор PHP расширений для чтения файлов Excel

В статье представлены различные PHP-расширения для чтения файлов XLS, XLSX, описаны их плюсы и минусы, а также примеры чтения.

PHPExcel

Огромная библиотека читает и формирует фалы xls, xlsx, csv.

Пример чтения файла в массив:

require_once __DIR__ . '/PHPExcel-1.8/Classes/PHPExcel/IOFactory.php'; // Файл xlsx $xls = PHPExcel_IOFactory::load(__DIR__ . '/test.xlsx'); // Первый лист $xls->setActiveSheetIndex(0); $sheet = $xls->getActiveSheet(); foreach ($sheet->toArray() as $row)

SimpleXLSX

• Менее прожорлив к памяти.
• Не всегда может прочитать файл, например файл сформированный PHPExcel.

require_once __DIR__ . '/simple-xlsx/simplexlsx.class.php'; // Файл xlsx $xlsx = new SimpleXLSX(__DIR__ . '/test.xlsx'); // Первый лист $sheet = $xlsx->rows(1); foreach ($sheet as $row)

PHP-ExcelReader

require_once __DIR__ . '/phpExcelReader/Excel/reader.php'; $data = new Spreadsheet_Excel_Reader(); $data->setOutputEncoding('UTF-8'); // Файл xls $data->read(__DIR__ . '/test.xls'); // Первый лист $sheet = $data->sheets[0]['cells']; foreach ($sheet as $row)

PHP-Excel-Reader

Форк библиотеки «PHP Excel Reader» с SourceForge предназначенный для вывода таблицы в HTML.

Например файл example.xls выведет следующим образом:

 table.excel < border: 1px solid #CCCCCC; border-collapse:collapse; font-family:sans-serif; font-size:12px; margin: 0 auto; >table.excel thead th, table.excel tbody th < border: 1px solid #CCCCCC; text-align: center; vertical-align:bottom; >table.excel tbody th < text-align:center; width:20px; >table.excel tbody td < vertical-align:bottom; >table.excel tbody td dump(true, true); ?>

Также у библиотеки есть методы для получения формата и содержания каждой ячейки по отдельности.

Nuovo Spreadsheet-Reader

Читает файлы XLSX, XLS, CSV и OpenOffice ods. Для чтения XLS используется предыдущая библиотека php-excel-reader.

require_once __DIR__ . '/spreadsheet-reader/php-excel-reader/excel_reader2.php'; require_once __DIR__ . '/spreadsheet-reader/SpreadsheetReader.php'; // Файл xlsx, xls, csv, ods. $Reader = new SpreadsheetReader(__DIR__ . '/test.xlsx'); // Номер листа. $Reader -> ChangeSheet(0); foreach ($Reader as $Row)

PHP-Spreadsheetreader

Откроет только файлы в формате XML Excel 2004.

$file = __DIR__ . '/test.xml'; require_once __DIR__ . '/SpreadsheetReader/SpreadsheetReader.php'; $reader = new SpreadsheetReader; // Файл xml $sheets = $reader->read(__DIR__ . '/test.xml'); // Выводим Первый лист foreach ($sheets[0] as $row)

xlsx-reader is a PHP library for fast and efficient reading of XLSX spreadsheet files. Its focus is on reading the data contained within XLSX files, disregarding all document styling beyond that which is strictly necessary for data type recognition. It is built to be usable for very big XLSX files in the magnitude of multiple GBs.

README.md

xlsx-reader is an extension of the XLSX-targeted spreadsheet reader that is part of spreadsheet-reader.

It delivers functionality to efficiently read in data contained within the given XLSX file.

The focus of this library is on delivering data contained in XLSX spreadsheet cells, not the document’s styling. As such, the library offers no support for XLSX capabilities that aren’t strictly necessary to achieve this goal. Only basic cell value formatting and shared string functionalities are supported.

• PHP 7.1.0 or newer, with at least the following optional features enabled:
  • Zip (see http://php.net/manual/en/zip.installation.php)
  • XMLReader (see http://php.net/manual/en/xmlreader.installation.php)

  Installation using Composer

  The package is available on Packagist. You can install it using Composer.

  composer require aspera/xlsx-reader 

  All data is read from the file sequentially, with each row being returned as an array of columns.

   use Aspera\Spreadsheet\XLSX\Reader; $reader = new Reader(); $reader->open('example.xlsx'); foreach ($reader as $row) < print_r($row); > $reader->close();

  XLSX files with multiple worksheets are also supported. The method getSheets() returns an array with sheet indexes as keys and Worksheet objects as values. The method changeSheet($index) is used to switch between sheets to read.

   use Aspera\Spreadsheet\XLSX\Reader; $reader = new Reader(); $reader->open('example.xlsx'); $sheets = $reader->getSheets(); foreach ($sheets as $index => $sheet_data) < $reader->changeSheet($index); echo 'Sheet #' . $index . ': ' . $sheet_data->getName(); // Note: Any call to changeSheet() resets the current read position to the beginning of the selected sheet. foreach ($reader as $row_number => $row) < echo 'Row #' . $row_number . ': ' . print_r($row, true); > > $reader->close();

  Options to tune the reader’s behavior and output can be specified via a ReaderConfiguration instance.

  For a full list of supported options and their effects, consult the in-code documentation of ReaderConfiguration.

   use Aspera\Spreadsheet\XLSX\Reader; use Aspera\Spreadsheet\XLSX\ReaderConfiguration; use Aspera\Spreadsheet\XLSX\ReaderSkipConfiguration; $reader_configuration = (new ReaderConfiguration()) ->setTempDir('C:/Temp/') ->setSkipEmptyCells(ReaderSkipConfiguration::SKIP_EMPTY) ->setReturnDateTimeObjects(true) ->setCustomFormats(array(20 => 'hh:mm')); // For a full list of supported options and their effects, consult the in-code documentation of ReaderConfiguration. $spreadsheet = new Reader($reader_configuration);

  Notes about library performance

  XLSX files use so-called «shared strings» to optimize file sizes for cases where the same string is repeated multiple times. For larger documents, this list of shared strings can become quite large, causing either performance bottlenecks or high memory consumption when parsing the document.

  To deal with this, the reader selects sensible defaults for maximum RAM consumption. Once this memory limit has been exhausted, the file system is used for further optimization strategies.

  To configure this behavior in detail, e.g. to increase the amount of memory available to the reader, a SharedStringsConfiguration instance can be attached to the ReaderConfiguration instance supplied to the reader’s constructor.

  For a full list of supported options and their effects, consult the in-code documentation of SharedStringsConfiguration.

   use Aspera\Spreadsheet\XLSX\Reader; use Aspera\Spreadsheet\XLSX\ReaderConfiguration; use Aspera\Spreadsheet\XLSX\SharedStringsConfiguration; $shared_strings_configuration = (new SharedStringsConfiguration()) ->setCacheSizeKilobyte(16 * 1024) ->setUseOptimizedFiles(false); // For a full list of supported options and their effects, consult the in-code documentation of SharedStringsConfiguration. $reader_configuration = (new ReaderConfiguration()) ->setSharedStringsConfiguration($shared_strings_configuration); $spreadsheet = new Reader($reader_configuration);

  Notes about unsupported features

  This reader’s purpose is to allow reading of basic data (text, numbers, dates. ) from XLSX documents. As such, there are no plans to extend support to include all features available for XLSX files. Only a minimal subset of XLSX capabilities is supported.

  In particular, the following should be noted in regard to unsupported features:

  • Display cell width is disregarded. As a result, in cases in which popular xlsx editors would shorten values using scientific notation or «#####»-placeholders, the reader will return un-shortened values instead.
  • Files with multiple internal shared strings files are not supported.
  • Files with multiple internal styles definition files are not supported.
  • Fractions are only partially supported. The results delivered by the reader might be slightly off from the original input.
