这篇“PHP如何读取excel文件”文章的知识点大部分人都不太理解,所以小编给大家总结了以下内容,内容详细,步骤清晰,具有一定的借鉴价值,希望大家阅读完这篇文章能有所收获,下面我们一起来看看这篇“php如何读取Excel文件”文章吧。

应该有ODBC的读取方法,还没有试,今天的方法简单了很多,只需要加载两个文件即可,这两个文件(OLERead.phpreader.php)我找了好长时间才找到,放在后面。

试验成功的代码:

<?phprequire_once 'reader.php';//加载Reader$excelData = new Spreadsheet_Excel_Reader();//创建 Reader$excelData->setOutputEncoding('utf-8');//设置文本输出编码$excelData->read("20210930.xls");//读取Excel文件echo '总行数:'.$excelData->sheets[0]['numRows'];//Excel行数echo '总列数:'.$excelData->sheets[0]['numCols'];//Excel列数 for ($i = 1; $i <= $excelData->sheets[0]['numRows']; $i++) {  $strRowData='';  for ($j = 1; $j <= $excelData->sheets[0]['numCols']; $j++) {       if ( isset( $excelData->sheets[0]['cells'][$i][$j] )){$strColData=$excelData->sheets[0]['cells'][$i][$j];$strRowData=$strRowData.'  '.$strColData;}echo $strRowData.'<br>';  }}?>

注意:在输出的时候判断一下,即isset( $excelData->sheets[0]['cells'][$i][$j]),不然可能会报错。

能读出来做处理就好办了。

reader.php文件内容:(新建一个reader.php,将代码拷入即可)
