PHP5.6读写excel表格文件操作示例

<?php
require_once 'Classes/PHPExcel.php';
require_once 'Classes/PHPExcel/IOFactory.php';
require_once 'Classes/PHPExcel/Reader/Excel5.php';
$file_url = './excel/phpLv.xls';
$objReader = PHPExcel_IOFactory::createReader('Excel5');
$objPHPExcel = $objReader->load($file_url);
//设置当前活动的工作表
$objPHPExcel->setActiveSheetIndex(1);
//拿到当前活动的表。以后操作就用这个了。劳资才不喜欢链式操作，太难看了好不啦
$activeSheet = $objPHPExcel->getActiveSheet();
//当前表最大行数
$highestRow = $activeSheet->getHighestRow();
//当前表最大列数
$highestColumn = $activeSheet->getHighestColumn();
echo "最大列：$highestColumn";
echo "最大行：$highestRow";
echo '<hr/>';
$cell = function ($cell) use ($activeSheet) {
  return $activeSheet->getCell("$cell")->getValue();
};
$str1 = $cell('A13');
echo $str1;
exit;
