How to Retrieve HTML Code from a Web Page in PHP?

Retrieving HTML Code of a Web Page in PHP

In PHP, there are multiple approaches to retrieve the HTML code of a web page. Let's explore two common methods:

Using url fopen Wrappers

If your PHP server allows url fopen wrappers, you can fetch the HTML code using the file_get_contents function:

<code class="php">$html = file_get_contents('https://stackoverflow.com/questions/ask');</code>

This method is simple and sufficient for basic needs.

Using cURL

For more advanced control, consider using the cURL functions:

<code class="php">$c = curl_init('https://stackoverflow.com/questions/ask');
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);

// Set other desired cURL options here...

$html = curl_exec($c);

if (curl_error($c))
    die(curl_error($c));

// Get the HTTP status code if needed
$status = curl_getinfo($c, CURLINFO_HTTP_CODE);

curl_close($c);</code>

cURL provides greater flexibility and allows you to customize various aspects of the request, such as headers, cookies, and authentication.
