PHP：致命错误：Class＆＃39; x＆＃39;没找到＆＃39; y＆＃39;在线＆＃39; z＆＃39;

Question

请解释一下错误的原因是什么......？

我看不到课程，但我没有看到任何require error

    var_dump(12);
    require('http://dev.credicom.de/spreadsheet/php-excel-reader/excel_reader2.php');
    require('http://dev.credicom.de/spreadsheet/SpreadsheetReader.php'); 

    $Reader = new SpreadsheetReader();
    foreach ($Reader as $Row)
    {
        print_r($Row);
    }
    die('priehali');

我收到以下错误：

 Fatal error: Class 'Spreadsheet\SpreadsheetReader' not found in /www/htdocs/w00e163f/credicom.de.dev/content/importExcel.php on line 14

Answer 1

require应具有文件的物理路径，而不是URL

require(__DIR__.'excel_reader2.php');
