如何设置PHP wkhtmltopdf

在 php 路径下，应能打开命令行输入php -v能够看到php版本信息。

然后执行以下三条：

cpp 复制代码

php -r "copy('https://install.phpcomposer.com/installer', 'composer-setup.php');"

php composer-setup.php

php -r "unlink('composer-setup.php');"

这时遇到报错：

bash 复制代码

Unable to find the wrapper "https" - did you forget to enable it when you configured PHP?

参考：https://www.cnblogs.com/ec04/p/12390050.html

1.windows下的PHP，只需要到php.ini中把extension=php_openssl.dll前面的;删掉，重启服务就可以了。

经查，我的 php 没有这一项，添加，然后 iisreset 。再次执行以上三条，通过，下载安装成功。

cpp 复制代码

最后参考：php使用wkhtmltopdf html转为ptf或图片_php wkhtmlto-CSDN博客

执行：composer require mikehaertl/phpwkhtmltopdf

这时有问题，需要改为：php composer.phar require mikehaertl/phpwkhtmltopdf

执行通过：

cpp 复制代码

最后是如何使用：

（这里要吐槽一下：网上的示例为何都不讲 require_once('...') 呢？）

php 复制代码

//定位文件位置
require_once('C:\php\vendor\mikehaertl\php-tmpfile\src\File.php');
require_once('C:\php\vendor\mikehaertl\php-shellcommand\src\Command.php');
require_once('C:\php\vendor\mikehaertl\phpwkhtmltopdf\src\Command.php');
require_once('C:\php\vendor\mikehaertl\phpwkhtmltopdf\src\Image.php');
require_once('C:\php\vendor\mikehaertl\phpwkhtmltopdf\src\Pdf.php');
//生成图片
use mikehaertl\wkhtmlto\Image;
//生成PDF
use mikehaertl\wkhtmlto\Pdf;

//生成HTML和CSS
$html = "
    <!DOCTYPE html>
    <html lang=\"en\">
    <head>
        <meta charset=\"UTF-8\">
        <title>Title</title>
    </head>
    <style>
        table {
            border-collapse: collapse;
            width: 100%;
            max-width: 600px;
            margin: 0 auto;
        }
        th, td {
            border: 1px solid #ddd;
            padding: 10px;
            text-align: center;
        }
        th {
            background-color:#f2f2f2;
        }
    </style>
    <body>
    <table>
        <tr>
            <th>姓名</th>
            <th>年龄</th>
            <th>性别</th>
        </tr>
        <tr>
            <td>张三</td>
            <td>20</td>
            <td>男</td>
        </tr>
        <tr>
            <td>李四</td>
            <td>25</td>
            <td>女</td>
        </tr>
    </table>
    </body>
    </html>";
//$html可以是文件路径也可以直接放html
$image = new Image($html);
// 懒得设置环境变量，直接把wkhtmltopdf安装路径写到这里就好
$image->binary = 'C:\Program Files\wkhtmltopdf\bin\wkhtmltoimage';
$image->saveAs('test.png');

$pdf = new Pdf($html);
// 懒得设置环境变量，直接把wkhtmltopdf安装路径写到这里就好
$pdf->binary = 'C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf';
$pdf->saveAs('test.pdf');
