mPDF：与它们的类同名的方法将不是PHP的未来版本中的构造函数; mPDF有一个不推荐使用的构造函数

Question

I'm new to mpdf and I'm having a problem implementing it on my project. I saw a link in Facebook that has a tutorial for mpdf, I read and followed all the instructions but unfortunately there is still an error about some deprecated value.

Here is the link I followed : http://codesquery.com/convert-html-pdf-codeiniter-using-mpdf/

And here is the screenshot of the problem:

I hope you guys can help me.

You can easily install mpdf by using composer in codeigniter. This is how I implemented composer in CodeIgniter 3.It is very easy. You have to install composer on your machine download it from https://getcomposer.org/. After installing composer in your pc,

1. Copy and paste composer.json file in the project folder to application folder.
2. In the config.php file $config['composer_autoload'] = TRUE;

Now you have composer in your project. Now i will saw you how to install mpdf using composer

1. Open cmd and direct to application folder
2. Inside application directory Type composer require mpdf/mpdf

Now a vendor folder will be created inside application folder and inside vendor folder you can see all your packages downloaded by composer.

Now since you autoloaded composer now you can just use the code given by mpdf official manual like in your controllers.

    function m_pdf(){ 

       $mpdf = new mPDF();

       // Write some HTML code:

       $mpdf->WriteHTML('Hello World');

       // Output a PDF file directly to the browser
       $mpdf->Output();
   }

Remember you don't need to type require_once APPPATH.'/vendor/mpdf/mpdf/mpdf.php'; since you already autoloader composer. If not prefer to autoload composer you must type require_once APPPATH.'/vendor/mpdf/mpdf/mpdf.php' at the beginning of each controllers where you use the mpdf vendor libraries.
