PhpGt / Curl

Object oriented cURL wrapper.

cURL object wrapper.

This library wraps PHP's native cURL extension functions with objects, for better code readability and testability.

Why? We wanted to lay an object oriented foundation for PHP.Gt/Fetch, our PHP implementation of the web's fetch API that uses cURL to create asynchronous HTTP calls with promises.

Example usage: Get a JSON object from a remote source

When working with HTTP calls, it is extremely common to work with JSON. This library removes the need of a lot of boilerplate code by buffering the output of exec() calls for easy retrieval later with output() or outputJson().

Example using PHP.Gt/Curl:

$curl = new Curl("https://catfact.ninja/fact");
$curl->exec();
$json = $curl->outputJson();
echo "Here's a cat fact: {$json->getString("fact")}";
echo PHP_EOL;
echo "The fact's length is {$json->getInt("length")} characters.";
echo PHP_EOL;

Same example using PHP's native curl_* functions:

// Using native functionality to achieve the same:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://catfact.ninja/fact");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
if(false === $result) {
	die("CURL error: " . curl_error($ch));
}
$json = json_decode($result);
if(is_null($json)) {
	die("JSON decoding error: " . json_last_error_msg());
}

// Note: No type checks are made on the `fact` and `length` properties here.
echo "Here's a cat fact: {$json->fact}";
echo PHP_EOL;
echo "The fact's length is {$json->length} characters.";
echo PHP_EOL;
