<?php
$url = "http://example.com";
$ch = curl_init($url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$pageContent = curl_exec($ch);

if ($pageContent === false) {
    echo "Curl error: " . curl_error($ch);
} else {
    echo $pageContent;
}

curl_close($ch);
?>

Sample output: The actual HTML content of http://example.com.

Deep Dive (Поглиблений Розбір)

Back in the day, file_get_contents() was popular for simple requests. Now, cURL (Client URL Library) is the go-to tool. It handles complex HTTP requests, supports various protocols, and allows for fine-grained control over headers, cookies, and more. Its versatility trumps older methods. When using cURL, remember to set the appropriate options, like CURLOPT_RETURNTRANSFER to ensure the result is returned, not printed. Handle errors gracefully by checking if $pageContent is false, then use curl_error() for diagnostic info.

Alternatives to consider, like PHP’s file_get_contents() for simple GET requests, or the Guzzle library for a more robust HTTP client, if dealing with a complex project where you need advanced features like persistent connections, asynchronous requests, or handling streams.
