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.php、reader.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）
