如何創建 function 以將數據導出到 excel 文件 PHP

Question

大家好，我有一個我構建的插件。 在表格中顯示數據，如下所示：

現在我需要在沒有庫的情況下將其導出到 PHP 中的 excel 文件中，因為這需要我將庫添加到moodle，我不太確定如何執行此操作。

這是在站點上的 html 中創建表的代碼。

<?php

    require_once('../../config.php');
    global $DB;

    $courseid = required_param('courseid', PARAM_INT);
    $syncid = optional_param('syncid', 0, PARAM_INT);

    $context = context_system::instance();
    $heading = get_string('pluginname', 'local_gradebook_sync');
    $title = get_string('pluginname', 'local_gradebook_sync');
    $url = new moodle_url('/local/gradebook_sync/sync.php', ['courseid' => $courseid]);

    $PAGE->set_context($context);
    $PAGE->set_heading($heading);
    $PAGE->set_title($title);
    $PAGE->set_url($url);

    $gradebook_sync = $DB->get_record('local_gradebook_sync', ['id' => $syncid]);
    $destination_course = get_course($gradebook_sync->destinationcourseid);

    echo $OUTPUT->header();

    echo $OUTPUT->heading($destination_course->fullname . ' (' . $destination_course->shortname . ')');

    $table = new html_table();
    $table->head = ['Section', 'Activity', 'Activity type', 'Status'];

任何人都可以幫忙，因為我真的很難過。

注意：如果有幫助，這是一個 Moodle 插件

提前致謝。

Answer 1

它應該可以幫助您而無需安裝任何軟件包

PHP_XLSXWriter

Answer 2

對於 Moodle，我建議先搜索代碼。

已經有一個 excel class 您可以使用。

例如，請參閱mod/survey/download.php

require_once("$CFG->libdir/excellib.class.php");

$workbook = new MoodleExcelWorkbook('-');

// Send HTTP headers
$downloadfilename = 'myfilename.xls';
$workbook->send($downloadfilename);

$myxls = $workbook->add_worksheet('myworksheet');

$headers = array("column1","column2","column3");
$row = 0;
$col = 0;
foreach ($headers as $header) {
    $myxls->write_string($row, $col++, $header);
}

foreach ($grades as $grade) {
    $row++;
    $col = 0;
    foreach ($grade as $name => $value) {
        $myxls->write_string($row, $col++, $value);
    }
}

$workbook->close();
