public function getCellByColumnAndRow($pColumn = 0, $pRow = 0) {

print_r(PHPExcel_Cell::columnIndexFromString('D'));exit; //echo 4

}

//phpexcel默认是没有冻结的，下面是冻结列。定二则定全部
$sheet->freezePane('A1');
$sheet->freezePane('B1');        
冻结行
$sheet->freezePane('D1');
$sheet->freezePane('D2');
不能再次定义A,b,c否则列冻结被替代

public function freezePaneByColumnAndRow($pColumn = 0, $pRow = 0){
    $this->freezePane(PHPExcel_Cell::stringFromColumnIndex($pColumn) . $pRow);
}
public function unfreezePane() {
   $this->freezePane('');
 }
$worksheet->setInputEncoding("UTF-8");
//$freeze = $sheet->getFreezePane();

用phpexcel批量设置单元格格式 

$style_obj = new PHPExcel_Style();
$style_array = array(
    'borders' => array(
        'top' => array('style' => PHPExcel_Style_Border::BORDER_THIN),
        'left' => array('style' => PHPExcel_Style_Border::BORDER_THIN),
        'bottom' => array('style' => PHPExcel_Style_Border::BORDER_THIN),
        'right' => array('style' => PHPExcel_Style_Border::BORDER_THIN)
    ),
    'alignment' => array(
        'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
        'vertical'   => PHPExcel_Style_Alignment::VERTICAL_CENTER,
        'wrap'       => true
    )
);
$style_obj->applyFromArray($style_array);
$sheet->setSharedStyle($style_obj, "A1:O35");

phpexcel大数据导出,数据追加（19万行，分20个sheet, 1万行是一个sheet,第一次到1个sheet数据，其他数据追加到excel分19次覆盖对应的sheet）

先用 PhpExcel 建立reader，再load文件，这样打开已经存在的文档，然后再建立writer，将reader中的数据都复制过来，再用 PhpExcel 进行数据修改，再以load的文件名覆盖保存。

<?php
require_once 'PHPExcel/IOFactory.php';
$reader = PHPExcel_IOFactory::createReader('Excel5'); //读取旧版 excel 档案
$PHPExcel = $reader->load("y.xls"); // 档案名称
$sheet = $PHPExcel->getSheet(0); // 读取第一个工作表(编号从 0 开始)
$highestRow = $sheet->getHighestRow(); // 取得总列数
for ($row = 1; $row <= $highestRow; $row++) {
    for ($column = 1; $column <= 6; $column++) {
        $val = $sheet->getCellByColumnAndRow($column, $row)->getValue();
    }
}
?>
