PHPExcel读取excel文件

????? 之前的博文已经对PHPExcel导出excel文件做了简单的总结,现对他读取excel做以下总结。(对数据量不会很大的建可以采用web直接用此方法读取,如果数据量会很大的话,还是建议web只做上传功能,读取、处理还是放后台吧。PHPExcel还是比较耗费时间、内存的。)

?

实例代码:

?

//首先导入PHPExcel
require_once 'PHPExcel.php';

$filePath = "test.xlsx";

//建立reader对象
$PHPReader = new PHPExcel_Reader_Excel2007();
if(!$PHPReader->canRead($filePath)){
    $PHPReader = new PHPExcel_Reader_Excel5();
    if(!$PHPReader->canRead($filePath)){
        echo 'no Excel';
        return ;
    }
}

//建立excel对象,此时你即可以通过excel对象读取文件,也可以通过它写入文件
$PHPExcel = $PHPReader->load($filePath);

/**读取excel文件中的第一个工作表*/
$currentSheet = $PHPExcel->getSheet(0);
/**取得最大的列号*/
$allColumn = $currentSheet->getHighestColumn();
/**取得一共有多少行*/
$allRow = $currentSheet->getHighestRow();

//循环读取每个单元格的内容。注意行从1开始,列从A开始
for($rowIndex=1;$rowIndex<=$allRow;$rowIndex++){
    for($colIndex='A';$colIndex<=$allColumn;$colIndex++){
        $addr = $colIndex.$rowIndex;
		$cell = $currentSheet->getCell($addr)->getValue();
        if($cell instanceof PHPExcel_RichText)     //富文本转换字符串
			$cell = $cell->__toString();
            
        echo $cell;
    
    }

}
Copy after login

?

?? ?这里需要说明的是上面注释中的“富文本转换字符串”。

???PHPExcel读取EXCEl文件中,如果单元格中的内容有两种字体时,读到的是富文本的对象:

例如:单元格中有内容:“测试1”,其中前半部分的“测试”字体为宋体,后半部分的“1”字体为Calibri,这时候通过

??? $cell = $sheet->getCell($addr)->getValue();

获取单元格的值。并打印:

PHPExcel_RichText Object(
	[_richTextElements:private] => Array
 	(
           	[0] => PHPExcel_RichText_TextElement Object ([_text:private] => 测试)
                     [1] => PHPExcel_RichText_Run Object
                     (
                     	[_font:private] => PHPExcel_Style_Font Object
                               (
                                	[_name:private] => Calibri
                                        [_size:private] => 11
                                        [_bold:private] => 
                                        [_italic:private] => 
                                        [_superScript:private] => 
                                        [_subScript:private] => 
                                        [_underline:private] => none
                                        [_strikethrough:private] => 
                                        [_color:private] => PHPExcel_Style_Color Object
                                        (
                                            [_argb:private] => FF000000
                                            [_isSupervisor:private] => 
                                            [_parent:private] => 
                                            [_parentPropertyName:private] => 
                                        )
                                        [_parentPropertyName:private] => 
                                        [_isSupervisor:private] => 
                                        [_parent:private] => 
                                        [colorIndex] => 8
                                    )
                                    [_text:private] => 1
                                )
                        )
                )
Copy after login

?

可以看到对这样的单元格不能直接读取单元格的文本内容。(注:这里的富文本是我自己的翻译,不知对否)。

另外,读取单元格的函数还有:

//列从0开始,行从1开始

$currentSheet ->getCellByColumnAndRow($colIndex,$rowIndex)->getValue();
