PhpSpreadsheet读取excel「建议收藏」

	composer require phpoffice/phpspreadsheet

<?php
require "vendor/autoload.php";
// $inputFileName = 'source.xlsx';
$inputFileName = 'compress.xlsx';
$sheetname = 'Sheet1';
/** 1.检测文件类型 **/
$inputFileType = \PhpOffice\PhpSpreadsheet\IOFactory::identify($inputFileName);
/** 2.根据类型创建合适的读取器对象 **/
$reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader($inputFileType);
// 3. 设置读取器选项
// $reader->setReadDataOnly(true);
$reader->setLoadSheetsOnly($sheetname);
class MyReadFilter implements \PhpOffice\PhpSpreadsheet\Reader\IReadFilter
{ 

public function readCell($column, $row, $worksheetName = '')
{ 

// 选定区域
if ($row >= 1 && $row <= 7) { 

if (in_array($column, range('A','B'))) { 

return true;
}
}
return false;
}
}
$filterSubset = new MyReadFilter();
// 使用过滤器
$reader->setReadFilter($filterSubset);
// 4.读取表格表对象
$spreadsheet = $reader->load($inputFileName);
// 5. 得到工作表
$workSheet = $spreadsheet->getActiveSheet();
// 6. 读取表格内容
$cellA1 = $workSheet->getCell('A1');
echo 'Value: ', $cellA1->getValue(), '; Address: ', $cellA1->getCoordinate(), PHP_EOL;
// 7.超出范围不读取
$cellA9 = $workSheet->getCell('A9');
echo 'Value: ', $cellA9->getValue(), '; Address: ', $cellA9->getCoordinate(), PHP_EOL;
