FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package polyfill
easy-excel/polyfill
PhpSpreadsheet-compatible PHP API backed by the easy-excel FrankenPHP
extension — spreadsheet heavy lifting (XML, ZIP, parsing, formulas) runs in
compiled Go via excelize, while your
code keeps using the PhpOffice\PhpSpreadsheet\* classes it already knows.
This package is the PHP half of xiidea/easy-excel
(the Go extension, build pipeline, benchmarks and design docs live there).
Versions are tagged in lockstep: vX.Y.Z here matches vX.Y.Z of the
extension and the ghcr.io/xiidea/frankenphp8.5-easy-excel:X.Y.Z image.
Why
Measured on the reference workload (write N rows × 10 mixed columns, PHP 8.5):
| Library | 100k rows | 1M rows | Peak PHP memory |
|---|---|---|---|
| PhpSpreadsheet 5.8 | 14.74s | — | 665MB at 100k |
| OpenSpout 4.x | 3.64s | 36.74s | 4MB |
| fast-excel-writer 6.x | 2.67s | 28.16s | 4MB |
| easy-excel | 0.82s | 7.85s | 4MB |
PhpSpreadsheet ergonomics at OpenSpout-class constant memory, several times faster than both. Styled-report numbers and the full methodology are in the main repository.
Requirements
-
PHP ≥ 8.3 running on FrankenPHP built with the easy-excel extension. The easiest way is the published image:
- Without the extension the package stays dormant: nothing is aliased,
nothing breaks. The same is true when the real
phpoffice/phpspreadsheetis installed — adoption can be incremental.
Install
The published image also ships this package at /opt/easy-excel/php, usable
as a path repository if you prefer pinning to the image:
Usage
Existing PhpSpreadsheet code works unchanged — the bootstrap lazily aliases
PhpOffice\PhpSpreadsheet\* to the native-backed EasyExcel\Compat\*
classes:
Reading works the same way (IOFactory::load, toArray, rangeToArray,
getCalculatedValue — formulas are evaluated by excelize's engine, 466/529
PhpSpreadsheet functions, coverage table).
You can also use the EasyExcel\Compat\* classes directly, or the flat
EasyExcel\Native ABI wrapper for maximum throughput. The raw extension
functions work without this package at all — reference:
NATIVE.md.
What's covered
- Workbook/worksheet: create/load/save (Xlsx, Csv), sheet management,
setCellValue(+Explicit),fromArray/toArray/rangeToArray, dimensions - Styles: font, fill, borders, alignment, protection, number formats —
applyFromArrayand the fullgetStyle(range)graph; styles applied before their rows are written ride the stream at zero cost - Structure: column widths/auto-size, row heights, merged cells, auto-filter, freeze panes, hyperlinks, comments, defined names, page setup
- Advanced: data validation, conditional formatting, images, sheet protection, charts (native declarative API), formula evaluation
- Load control: heavy operations pass a semaphore + memory budget;
overload surfaces as
EasyExcel\Exception\Overloaded(map it to HTTP 429) instead of OOM-killing the worker
The precise matrix and every documented divergence: COMPAT.md.
Configuration (environment)
| Env var | Default | Meaning |
|---|---|---|
EASY_EXCEL_MAX_CONCURRENT |
max(2, NumCPU) |
heavy ops (open/save/scan) in flight |
EASY_EXCEL_ACQUIRE_TIMEOUT_MS |
30000 |
wait before Overloaded is raised |
EASY_EXCEL_MEMORY_BUDGET_MB |
512 |
live-workbook memory circuit breaker |
EASY_EXCEL_ALLOWED_PATHS |
unset (any local path) | colon-separated base dirs for load/save |
EASY_EXCEL_FORCE_ALIAS |
unset | 1 forces the aliases even when phpspreadsheet is installed (used by the test suite) |
Tests
The end-to-end suite (real extension, Docker) runs in the main repository's CI.
