How to make a simple HTTP GET request using cURL in PHP?

To make a simple HTTP GET request using cURL in PHP, you can follow these steps:

Step 1: Initialize cURL session using curl_init().

$curl = curl_init();

Step 2: Set the URL you want to make the GET request to using curl_setopt() with the option CURLOPT_URL.

curl_setopt($curl, CURLOPT_URL, 'http://example.com');

Step 3: Specify that you want to receive the response as a string by setting CURLOPT_RETURNTRANSFER option to true.

curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

Step 4: Execute the request using curl_exec().

$response = curl_exec($curl);

Step 5: Close the cURL session using curl_close().

curl_close($curl);

Here's the complete code:

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, 'http://example.com');
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($curl);
curl_close($curl);

After executing these steps, the response from the HTTP GET request can be accessed through the $response variable.
