README

This php-class can read Excel compatible spreadsheets in XLSX format (Office 2007+). It only reads data, but it does it very quickly and with minimal memory usage.

If you want to read colors, formats and other properties you need use PhpSpreadsheet. But if you only want data then your choice is FastExcelReader.

By the way, FastExcelWriter also exists - https://github.com/aVadim483/fast-excel-writer

Installation

Use composer to install FastExcelReader into your project:

composer require avadim/fast-excel-reader

Also you can download package and include autoload file of the library:

require 'path/to/fast-excel-writer/src/autoload.php';

Usage

You can find more examples in /demo folder

Simple example

use \avadim\FastExcelReader\Excel;

$file = __DIR__ . '/files/demo-01-base.xlsx';

// Open XLSX-file
$excel = Excel::open($file);

// Read all rows
$result = $excel->readRows();

You will get this array:

Array
(
    [1] => Array
        (
            ['A'] => 'col1'
            ['B'] => 'col2'
        )
    [2] => Array
        (
            ['A'] => 111
            ['B'] => 'aaa'
        )
    [3] => Array
        (
            ['A'] => 222
            ['B'] => 'bbb'
        )
)

// Read rows and use the first row as column keys
$result = $excel->readRows(true);

You will get this result:

Array
(
    [2] => Array
        (
            ['col1'] => 111
            ['col2'] => 'aaa'
        )
    [3] => Array
        (
            ['col1'] => 222
            ['col2'] => 'bbb'
        )
)

Also you can read a one dimensional array

$result = $excel->readCells();

Result here:

Array
(
    ['A1'] => 'col1'
    ['B1'] => 'col2'
    ['A2'] => 111
    ['B2'] => 'aaa'
    ['A3'] => 222
    ['B3'] => 'bbb'
)

Advanced example

use \avadim\FastExcelReader\Excel;

$file = __DIR__ . '/files/demo-02-advanced.xlsx';

$excel = Excel::open($file);

$result = [
    'sheets' => $excel->getSheetNames() // get all sheet names
];

$result['#1'] = $excel
    // select sheet by name
    ->selectSheet('Demo1') 
    // select area with data where the first row contains column keys
    ->setReadArea('B4:D11', true)  
    // set date format
    ->setDateFormat('Y-m-d') 
    // set key for column 'C' to 'Birthday'
    ->readRows(['C' => 'Birthday']); 

// read other arrays with custom column keys
$columnKeys = ['B' => 'year', 'C' => 'value1', 'D' => 'value2'];
$result['#2'] = $excel
    ->selectSheet('Demo2', 'B5:D13')
    ->readRows($columnKeys);

$result['#3'] = $excel
    ->setReadArea('F5:H13')
    ->readRows($columnKeys);

If necessary, you can fully control the reading process using the method readSheetCallback with callback-function

use \avadim\FastExcelReader\Excel;

$excel = Excel::open($file);

/**
 * A callback function that gets the value of each cell 
 *
 * @param int $row Row number
 * @param string $col Column char
 * @param mixed $val Cell value
 *
 * @return bool
 */
function readCellCallback($row, $col, $val)
{
    // Function implementation

    // if the function returns true then data reading is interrupted  
    return false;
}

$excel->readSheetCallback('readCellCallback');
