Extracting Site data through Web Crawler outputs error due to mis-match of Array Index

Question

I been trying to extract site table text along with its link from the given table to (which is in site1.com) to my php page using a web crawler.

But unfortunately,

Answer 1

Instead of writing your own parser solution you could use an existing one like Symfony's DomCrawler component: http://symfony.com/doc/current/components/dom_crawler.html

$crawler = new Crawler($returned_content);
$linkTexts = $crawler->filterXPath('//a')->each(function (Crawler $node, $i) {
    return $node->text();
});

Or if you want to traverse the DOM tree yourself you can use DOMDocument's loadHTML http://php.net/manual/en/domdocument.loadhtml.php

$document = new DOMDocument();
$document->loadHTML($returned_content);
foreach ($document->getElementsByTagName('a') as $link) {
    $text = $link->nodeValue;
}

EDIT:

To get the links you want, the code assumes you have a $returned_content variable with the HTML you want to parse.

// creating a new instance of DOMDocument (DOM = Document Object Model)
$domDocument = new DOMDocument();
// save previous libxml error reporting and set error reporting to internal
// to be able to parse not well formed HTML doc
$previousErrorReporting = libxml_use_internal_errors(true);
$domDocument->loadHTML($returned_content);
libxml_use_internal_errors($previousErrorReporting);
$links = [];
/** @var DOMElement $node */
// getting all  element from the HTML
foreach ($domDocument->getElementsByTagName('a') as $node) {
    $parentNode = $node->parentNode;
    // checking if the  is under a  that has class="FootNotes2"
    $isChildOfAFootNotesTd = $parentNode->nodeName === 'td' && $parentNode->getAttribute('class') === 'FootNotes2';
    // checking if the  has class="Links2"
    $isLinkOfLink2Class = $node->getAttribute('class') == 'Links2';
    // as I assumed you wanted links from the  this check makes sure that both of the above conditions are fulfilled
    if ($isChildOfAFootNotesTd && $isLinkOfLink2Class) {
        $links[] = [
            'href' => $node->getAttribute('href'),
            'text' => $parentNode->textContent,
        ];
    }
}

print_r($links);

This will create you an array similar to:

Array
(
    [0] => Array
    (
        [href] => /files/forum/2017/1/837242.php
        [text] => Q@Q Drill Time ① - cardio69
    ) 
    [1] => Array
    (
        [href] => /files/forum/2017/1/837356.php
        [text] => study partner in Houston - lacy
    )
    [2] => Array
    (
        [href] => /files/forum/2017/1/837110.php
        [text] => Serious dedicated study partner for U World - step12013
    )
