    curl_init

    (PHP 4 >= 4.0.2, PHP 5, PHP 7)

    curl_init — Inizializza una sessione CURL

    Descrizione

    resource curl_init ([ string $url = NULL ] )

    Inizializza una nuova sessione e restituisce un gestore cURL da usare con le funzioni curl_setopt(), curl_exec(), e curl_close().

    Elenco dei parametri

    url

    Se viene fornita, l'opzione CURLOPT_URL verrà impostata al suo valore. Si può impostare manualmente quest'ultima, usando la funzione curl_setopt().

    Nota:

    Il protocollo file viene disabilitato da cURL se viene impostato open_basedir.

    Valori restituiti

    Restituisce un gestore cURL in caso di successo, FALSE in caso di errore.

    Esempi

    Example #1 Inizializzare una nuova sessione cURL e scarica una pagina web

    <?php
    // crea una nuova risorsa cURL
    $ch = curl_init();

    // imposta l'URL e le altre opzioni appropriate
    curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
    curl_setopt($ch, CURLOPT_HEADER, 0);

    // imposta l'URL e lo passa al browser
    curl_exec($ch);

    // chiude la risorsa cURL, e libera le risorse di sistema
    curl_close($ch);
    ?>

    Just to clarify:

    Spaces in the URL need to be replaced with a %20.

    Spaces in the querystring need to be replaced with a +

    Curl_init as well as CURLOPT_URL don't like to have static strings as parameter.

    I came across this by accident and it took me very long to find out. curl_exec will throw error 3 (Malformed) and you tipple check the URL in it's variable only to find by trial and error that it's declaration is the culprit.
    So never do this:

    static $someurl = "http://www.example.com/interfacce.php";
    ....
    $ch=curl_init($someurl);
    ....
    $return=curl_exec($ch);

    Cheers

    curl_init() has undefined behavior if you pass 'false' to it and can crash when you try to copy the resulting handle using curl_copy_handle(). Keep this in mind if you create a wrapper object for CURL.

    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.

    e.g. you can check how many characters are on test_1.php

    or you can it use for more, i have used this function for a nagios check.

    <?PHP
    echo "CURL - function test <br>" ;
    if (    $load == 1){
    function     webcheck ($url) {
                $ch = curl_init ($url) ;
                curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1) ;
                $res = curl_exec ($ch) ;
                curl_close ($ch) ;
            return (    $res) ;
    }
    echo     "url = $url <br>" ;

    $erg = webcheck("my_page.php/test_1.php") ;
    $zahl = strlen ($erg) ;
    echo     "length = $zahl " ;
    ?>
