我如何在 CakePHP 4 中解析和读取 excel 文件？

Question

我想阅读我的 excel 文件，它是 xlsx 格式的。出现一些错误。我能做什么？这是 cakephp 4。我在那里使用 SimpleXLSX class。有我的索引 PHP 文件。 index.php

<h2>Upload form</h2>
<form method="post" enctype="multipart/form-data">
    <input type="file" name="file"  />
    <input type="submit" value="Parse" />
</form>

<?php

//https://github.com/shuchkin/simplexlsx/blob/master/src/SimpleXLSX.php THIS CLASS I USE THERE

ini_set('error_reporting', E_ALL);
ini_set('display_errors', true);

echo '<h1>XLSX to HTML</h1>';

if (isset($_FILES['file'])) {
    
    if ( $xlsx = SimpleXLSX::parse( $_FILES['file']['tmp_name'] ) ) {

        echo '<h2>Parsing Result</h2>';
        echo '<table border="1" cellpadding="3" style="border-collapse: collapse">';

        $dim = $xlsx->dimension();
        $cols = $dim[0];

        foreach ( $xlsx->rows() as $k => $r ) {
            echo '<tr>';
            for ( $i = 0; $i < $cols; $i ++ ) {
                echo '<td>' . ( isset( $r[ $i ] ) ? $r[ $i ] : '&nbsp;' ) . '</td>';
            }
            echo '</tr>';
        }
        echo '</table>';
    } else {
        echo SimpleXLSX::parseError();
    }
}

控制器中没有什么可写的。

excelController.php

<?php
    
    namespace App\Controller;
    
    class excelController extends AppController
    {
        /**
         * Index method
         *
         * @return \Cake\Http\Response|null|void Renders view
         */
        public function index()
        {
            
        }
    }

$i++;

}

回声“”；

在视图和控制器中使用此代码 '''$data = $this->request->data; 如果（$数据['file']）{

        if ( $xlsx = SimpleXLSX::parse( $data['file']['tmp_name'] ) ) {
            $dim = $xlsx->dimension();
            $cols = $dim[0];

            $this->set(compact('xlsx', 'dim', 'cols'));
        } else {
            echo SimpleXLSX::parseError();
        }
    }'''
