curl_init (PHP 4 >= 4.0.2, PHP 5) curl_init -- Инициализирует сеанс CURL Описаниеresource curl_init ( [string url] )
curl_init() создает новый сеанс CURL
и возвращает дескриптор, который используется с функциями
curl_setopt(), curl_exec()
и curl_close(). Если передан необязательный
аргумент url, опция CURLOPT_URL будет
автоматически установлена в значение этого аргумента.
Если этот аргумент не передан, необходимо использовать функцию
curl_setopt().
Пример 1.
Инициализация сеанса CURL и загрузка web-страницы

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
?>

For some reason on some webservers it may not be able to understand what cURL is doing. If you're getting unexpected results (like getting no output when the URL is valid) while using curl_init(). Add a trailing slash '/' after the url if you haven't done so already.

The curl-functions can be used to check the ICQ-webstatus from an icq-number, to get the status as a string rather than as one of those standard images provided from ICQ. This can also be used to place your own Image instead of simple text, to show ones online-status, of course if activated in the options. The idea behind is to get just the text from the apache-site that would lead us to the picture that shows the online status. curl does not do any redirect, as long as we don't set CURLOPT_FOLLOWLOCATION. This is nice because the image can change, as long as the paths and filenames (contained in the site-text) don't. The different states are stored in a short array of unsigned crc-values.
<?php
class ICQ {
var $crc = array('253889085' => 'offline', '1177883536' => 'online', '1182613274' => 'hidden');
function getCrc($url) {
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_HEADER, 0);
ob_start();
curl_exec ($ch);
curl_close ($ch);
$cache = ob_get_contents();
ob_end_clean();
return (string)abs(crc32($cache));
}
function status($number) {
$check = $this->getCrc( 'http://status.icq.com/online.gif?icq=' . $number . '&img=5');
if (in_array($check, array_keys($this->crc))) {
return $this->crc[$check];
}
return false;
}
}
?>
Usage:
<?php
$icq = new ICQ();
print($icq->status('123456789'));
?>
Outputs 'online', 'offline' or 'hidden'.

... And the text file stand in the server in the same folder that the script.
This is the function code.-
<?php
