How To Convert This OOP To Procedural Style Php ?

developer_web

Folks,

I am a beginner and still on Procedural Style Php.
Do you mind converting this code to Procedural Style so I can learn from it to extract links off from a cURL fetched webpage ?

<?php 

//Code from: https://potentpages.com/web-crawler-development/tutorials/php/techniques 

//Assuming your contents are in a variable called $contents
//New DOM Document
$document = new DOMDocument;
//Load HTML in $contents variable
$document->loadHTML($contents);
//Get all links
if($links = $document->getElementsByTagName('a')) {
    //Loop through all links
    foreach($links as $node) {
        //Get link location (href)
        $link_href = $node->getAttribute('href');
        //Get link text
        $link_text = $node->nodeValue;
    }
}

?>

Cheers!

Have you looked at the official PHP manual to see how functions are used in either OO or Procedural? Plenty of examples so that you can learn to do this yourself.

Oh man, that link just lists a hundred more links!

That code is already procedural. Yes, it uses the built-in DOMDocument class, and therefore you have to use object/method notation via the -> operator, but that's the only option if you want to use DOMDocument: there are no corresponding procedural-style PHP functions for it.

All you need is to research how to use the PHP cURL functions to grab the desired HTML from a URL and put the HTML into that $document variable, and then do whatever DOM manipulations you want. 🤷‍♂️

That is THE MANUAL. Learn to use it. It is not "links" but an index to all of the php functions covered in the book. IF you don't handle that well, perhaps you are heading into waters you don't want to be in.
