  • This table is generated dynamically or has how to customize it by placing a class in the td for example?

  • In case I do not have access to the source code in case it is generated Tstr0 ,Tstr1 , Tstr2 more I would like to take only from the last position that is zero

  • What would be this URL you cite? It’s an external page from which you want to extract the information or is a page from your application even?

  • An external page

  • And it requires authentication, right? If yes, I already go ahead to edit your question and put all this information - which are crucial to solving the problem.

  • You will need the functions curl to get the HTML code from the page, performing the proper authentication. Then, with the PHP class DOMDocument you can treat HTML by searching for the row of the desired table through the method getElementById("TStr0") (from PHP, there is no JS here), after searching for the fourth column of this element and extracting its contents.

  • I understood more I don’t know how to do this

  • I know the basics of php

  • 1

    Now you know where to start studying.

  • Kkk because it is necessary to study function cur that first to authenticate the page?

  • I understood, but I confess that the question was very ambiguous, for your case it is normal to use Curl https://imasters.com.br/artigo/4140/php/usando-a-biblioteca-curl-do-php?trace=1519021197&source=single
