用PHPExcel读取Excel 2007 或者Excel2003文件,需要的朋友,可以参考下。

涉及知识点:

php对excel文件进行循环读取

php对字符进行ascii编码转化,将字符转为十进制数

php对excel日期格式读取,并进行显示转化

php对汉字乱码进行编码转化

代码如下:

require_once 'PHPExcel.php';

/**对excel里的日期进行格式转化*/
function GetData($val){
$jd = GregorianToJD(1, 1, 1970);
$gregorian = JDToGregorian($jd+intval($val)-25569);
return $gregorian;/**显示格式为 “月/日/年” */
}

$filePath = 'test.xlsx';

$PHPExcel = new PHPExcel();

/**默认用excel2007读取excel,若格式不对,则用之前的版本进行读取*/
$PHPReader = new PHPExcel_Reader_Excel2007();
if(!$PHPReader->canRead($filePath)){
$PHPReader = new PHPExcel_Reader_Excel5();
if(!$PHPReader->canRead($filePath)){
echo 'no Excel';
return ;
}
}

$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 = $currentSheet->getHighestRow();
/**从第二行开始输出,因为excel表中第一行为列名*/
for($currentRow = 2;$currentRow /**从第A列开始输出*/
for($currentColumn= 'A';$currentColumn$val = $currentSheet->getCellByColumnAndRow(ord($currentColumn) - 65,$currentRow)->getValue();/**ord()将字符转为十进制数*/
if($currentColumn == 'A')
{
echo GetData($val)."\t";
}else{
//echo $val;
/**如果输出汉字有乱码,则需将输出内容用iconv函数进行编码转换,如下将gb2312编码转为utf-8编码输出*/
echo iconv('utf-8','gb2312', $val)."\t";
}
}
echo "";
}
echo "\n";
?>
