PHP通过phpExcel类库读取EXCEL文件的方法

个人私藏 xx2008 431浏览 0评论

有些时候会用到利用PHP读取EXCEL文件,对于PHP来说读取EXCEL文件要比写入EXCEL文件文件简单点,这里借助网上的一个EXCEL类库实现PHP读取EXCEL文件。首先将一下类库保存为phpExcel.php

然后调用上面保存的phpExcel类,具体调用方法参考下面的调用代码,将以下代码保存为excel.php,其中test.xls为需要读取的Excel文件,运行后将会输出一个Excel文件test.xls的内容,本方法在Excel2007的文件上测试有效。

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<?php
require_once 'phpExcel.php';
$data = new Spreadsheet_Excel_Reader();
$data->setOutputEncoding('utf-8');
$data->read('test.xls');
error_reporting(E_ALL ^ E_NOTICE);
echo "<table border=1>";
for ($i = 1; $i <= $data->sheets[0]['numRows']; $i++) {
echo "<tr>";
for ($j = 1; $j <= $data->sheets[0]['numCols']; $j++) {
echo "<td>".$data->sheets[0]['cells'][$i][$j]."</td>";
}
echo "</tr>";
}
echo "</table>";
?>
