Php 如何将页面上显示的数据导出为pdf/excel？

我有一张这样的表格：

<form method="post" action="track_reports.php" name="form">
                    <table id="mytable">
                        <tr>
                            <td>
                                <input type="checkbox" name="chkBadge" onClick="apply(this.checked, 'textBox')"> <font class="category">Badge ID</font>
                            </td>

                            <td>
                                <input id="textBox" class="text sign" type="text" name="badge_id" disabled="disabled">
                            </td>
                        </tr>

                        <tr>
                            <td>
                                <input type="checkbox" name="chkEmp" onClick="apply(this.checked, 'textBox2')"> <font class="category">Employee Name</font>
                            </td>

                            <td>
                                <input id="textBox2" class="text sign" type="text" name="employee_name" disabled="disabled">
                            </td>
                        </tr>

                        <tr>
                            <td>
                                <input id="myCheckBox" type="checkbox" name="chkEmpOtDate" onClick="apply(this.checked, 'textBox3', 'textBox4')"> <font class="category">OT Date</font>
                            </td>

                            <td>
                                <font class="category">From</font> <input class="text sign" id="textBox3" type="text" name="alamat" disabled="disabled"> <font class="category">To</font> <input class="text sign" id="textBox4" type="text" name="alamat" disabled="disabled">
                            </td>
                        </tr>

                        <tr>
                            <td></td>
                            <td>
                                <input type="submit" name="submit" value="Submit" disabled>
                            </td>
                        </tr>
                    </table>
                </form>

提交的报告
对于以其他文件格式编写代码来说，直接编写代码并不容易，有些库提供了简单的接口来完成这类工作

fpdf是我用来转换为PDF的最好的库

phpexcel也是一个非常好的库，可用于转换为excel、PDF和多种格式
