i just started using curl, please tell me how can i save the td value or innerhtml into a variable. here is my code:

$xx = "mylink.html";

$cURL = curl_init();



curl_setopt($cURL, CURLOPT_URL, $xx);

curl_setopt($cURL, CURLOPT_HEADER,0);



curl_setopt($cURL, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($cURL, CURLOPT_COOKIESESSION, true);

curl_setopt($cURL, CURLOPT_FOLLOWLOCATION, 1);

$strPage = curl_exec($cURL);

curl_close($cURL);



  $pattern = '#<tbody>(.*?)</tbody>#';

  if( preg_match($pattern, $strPage, $match)){

    $catch = $match[0];

    print_r($match[0]);

  }else{

    echo 'Could not find it';

  }

here is the output:

<tbody class="highlighted"><tr class="xx"><td>value1</td><td>value2</td><td>value3</td><td>value4</td><td>value5</td></tr></tbody>

My Answer:
Sure! You can use the `DOMDocument` class in PHP to parse the HTML content and extract the values of the `` elements. Here is an example code snippet:

php
// Initialize cURL session
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, 'http://example.com'); // URL of the webpage
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute cURL session
$response = curl_exec($ch);

// Close cURL session
curl_close($ch);

// Create a new DOMDocument object
$dom = new DOMDocument();
$dom->loadHTML($response);

// Get all elements
$tds = $dom->getElementsByTagName('td');

// Loop through each element and save its value to a variable
foreach ($tds as $td) {
$tdValue = $td->nodeValue;
// Do something with $tdValue
echo $tdValue . "\n";
}


In this code snippet, we first make a cURL request to fetch the HTML content of a webpage. Then, we use the `DOMDocument` class to parse the HTML content and extract the values of the `` elements. Finally, we loop through each `` element and save its value to a variable `$tdValue`. You can modify the code to store the values in an array or any other data structure as per your requirement.
