Slam PHPExcel old&faster

This package is NOT intended to be complete and flexible, but to be fast.

PHPOffice/PHPExcel and PHPOffice/PhpSpreadsheet are great libraries, but abstract everything in memory before writing to the disk. This is extremely inefficent and slow if you need to write a giant XLS with thousands rows and hundreds columns.

Based on Spreadsheet_Excel_Writer v0.9.3, which can be found active on Github. This is not a fork: I copied it and adapted to work with PHP 7.1 and applied some coding standard fixes and some Scrutinizer patches.

Installation

composer require slam/php-excel

Usage

From version 4 the code is split in two parts:

1. Slam\Excel\Pear namespace, the original Pear code
2. Slam\Excel\Helper namespace, an helper to apply a trivial style on a Table structure:

use Slam\Excel\Helper as ExcelHelper; require __DIR__ . '/vendor/autoload.php'; // Being an Iterator, the data can be any dinamically generated content // for example a PDOStatement set on unbuffered query $users = new ArrayIterator([ [ 'column_1' => 'John', 'column_2' => '123.45', 'column_3' => '2017-05-08', ], [ 'column_1' => 'Mary', 'column_2' => '4321.09', 'column_3' => '2018-05-08', ], ]); $columnCollection = new ExcelHelper\ColumnCollection([ new ExcelHelper\Column('column_1', 'User', 10, new ExcelHelper\CellStyle\Text()), new ExcelHelper\Column('column_2', 'Amount', 15, new ExcelHelper\CellStyle\Amount()), new ExcelHelper\Column('column_3', 'Date', 15, new ExcelHelper\CellStyle\Date()), ]); $filename = sprintf('%s/my_excel_%s.xls', __DIR__, uniqid()); $phpExcel = new ExcelHelper\TableWorkbook($filename); $worksheet = $phpExcel->addWorksheet('My Users'); $table = new ExcelHelper\Table($worksheet, 0, 0, 'My Heading', $users); $table->setColumnCollection($columnCollection); $phpExcel->writeTable($table); $phpExcel->close();
