curl_getinfo

(PHP 4 >= 4.0.4, PHP 5, PHP 7, PHP 8)

curl_getinfo — Ottiene informazioni riguardo ad uno specifico trasferimento

Descrizione

curl_getinfo(resource $ch, int $opt = 0): mixed

Ottiene informazioni sull'ultimo trasferimento.

Elenco dei parametri

ch

Un identificativo cURL restituito da curl_init().

opt

Questo potrebbe essere una delle seguenti costanti:

CURLINFO_EFFECTIVE_URL - L'ultimo URL effettivo
CURLINFO_HTTP_CODE - L'ultimo codice HTTP ricevuto
CURLINFO_FILETIME - L'orario remoto del documento recuperato, se viene restituito -1 l'orario del documento è sconosciuto
CURLINFO_TOTAL_TIME - Il tempo totale in secondi della transazione per l'ultimo trasferimento
CURLINFO_NAMELOOKUP_TIME - Il tempo in secondi finchè la risoluzione dei nomi non è stata completata
CURLINFO_CONNECT_TIME - Il tempo in secondi impiegato per stabilire la connessione
CURLINFO_PRETRANSFER_TIME - Il tempo in secondi dall'inizio fino a poco prima che il trasferimento del file cominciasse
CURLINFO_STARTTRANSFER_TIME - Il tempo in secondi fino a quando il primo byte è in procinto di essere trasferito
CURLINFO_REDIRECT_COUNT - Il numero dei reindirizzamenti, con l'opzione CURLOPT_FOLLOWLOCATION abilitata
CURLINFO_REDIRECT_TIME - Il tempo in secondi di tutti le fasi di reindirizzamento prima che la transazione finale non venga avviata, con l'opzione CURLOPT_FOLLOWLOCATION abilitata
CURLINFO_REDIRECT_URL - Con l'opzione CURLOPT_FOLLOWLOCATION disabilitata: l'URL di reindirizzamento trovato nell'ultima transazione, che dovrebbe essere richiesto manualmente dopo. Con l'opzione CURLOPT_FOLLOWLOCATION abilitata: questo è vuoto. L'URL di reindirizzamento in questo caso è disponibile in CURLINFO_EFFECTIVE_URL
CURLINFO_PRIMARY_IP - L'indirizzo IP della connessione più recente
CURLINFO_PRIMARY_PORT - La porta di destinazione della connessione più recente
CURLINFO_LOCAL_IP - L'indirizzo IP locale (sorgente) della connessione più recente
CURLINFO_LOCAL_PORT - La porta locale (sorgente) della connessione più recente
CURLINFO_SIZE_UPLOAD - Numero totale di byte caricati (in upload)
CURLINFO_SIZE_DOWNLOAD - Numero totale di byte scaricati
CURLINFO_SPEED_DOWNLOAD - Velocità di download media
CURLINFO_SPEED_UPLOAD - Velocità di upload media
CURLINFO_HEADER_SIZE - Dimensione totale di tutti gli header ricevuti
CURLINFO_HEADER_OUT - La stringa di richiesta inviata. Per farlo funzionare, aggiungere l'opzione CURLINFO_HEADER_OUT al gestore chiamando curl_setopt()
CURLINFO_REQUEST_SIZE - Dimensione totale delle richieste effettuate, attualmente solo per le richieste HTTP
CURLINFO_SSL_VERIFYRESULT - Risultato della verifica del certificato SSL richiesto dall'impostazione CURLOPT_SSL_VERIFYPEER
CURLINFO_CONTENT_LENGTH_DOWNLOAD - dimensione-del-contenuto del download, letto dal campo Content-Length:
CURLINFO_CONTENT_LENGTH_UPLOAD - Dimensione specificata dell'upload
CURLINFO_CONTENT_TYPE - Il Content-Type: del documento richiesto, NULL indica che il server non ha inviato un header Content-Type: valido
CURLINFO_PRIVATE - Dati privati associati con questo gestore cURL, precedentemente impostati con l'opzione CURLOPT_PRIVATE di curl_setopt()

Valori restituiti

Se viene dato opt, viene restituito il suo valore. Altrimenti, restituisce un array associativo con i seguenti elementi (che corrispondono a opt), o false in caso di fallimento:

"url"
"content_type"
"http_code"
"header_size"
"request_size"
"filetime"
"ssl_verify_result"
"redirect_count"
"total_time"
"namelookup_time"
"connect_time"
"pretransfer_time"
"size_upload"
"size_download"
"speed_download"
"speed_upload"
"download_content_length"
"upload_content_length"
"starttransfer_time"
"redirect_time"
"certinfo"
"primary_ip"
"primary_port"
"local_ip"
"local_port"
"redirect_url"
"request_header" (Questo è impostato solo se CURLINFO_HEADER_OUT è stato impostato da una chiamata precedente a curl_setopt())

Notare che i dati privati non sono inclusi nell'array associativo e dovrebbero essere recuperati individualmente con l'opzione CURLINFO_PRIVATE.

CURLINFO_HTTP_CODE does not return a string, as the docs say, but rather an integer.

<?php
    $c = curl_init('http://www.example.com/');
    if(curl_getinfo($c, CURLINFO_HTTP_CODE) === '200') echo "CURLINFO_HTTP_CODE returns a string.";
    if(curl_getinfo($c, CURLINFO_HTTP_CODE) === 200) echo "CURLINFO_HTTP_CODE returns an integer.";
    curl_close($c);
?>

returns

"CURLINFO_HTTP_CODE returns an integer."

Note, header_size include "\r\n\r\n". So if you use CURLOPT_FOLLOWLOCATION>0, CURLOPT_HEADER=true, CURLOPT_RETURNTRANSFER=true right way splite header/body:

$response = curl_exec($ch);
$curl_info = curl_getinfo($ch);
curl_close($ch);
$header_size = $curl_info['header_size'];
$header = substr($response, 0, $header_size);
$body = substr($response, $header_size);

Here you have a function that I use to get the content of a URL using cURL. This uses curl_getinfo to know if it is a regular URL or maybe a redirection.

I hope it would be useful for you:

function getUrlContent($url){
 $ch = curl_init();
 curl_setopt($ch, CURLOPT_URL, $url);
 curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)');
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
 curl_setopt($ch, CURLOPT_TIMEOUT, 5);
 $data = curl_exec($ch);
 $httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
 curl_close($ch);
 return ($httpcode>=200 && $httpcode<300) ? $data : false;
}

Just a quick note: if you want to use curl_getinfo() with option CURLINFO_HEADER_OUT in order to debug your cURL request, you must add curl_setopt($handle, CURLINFO_HEADER_OUT, true); first while specifying the options.

curl_getinfo($ch) will also return 'redirect_url' if there is one (even if CURLOPT_FOLLOWLOCATION set to false).
I don't know why it's not in the doc..

There is a constant missing from that list.  CURLINFO_REDIRECT_COUNT will give you the number of redirects it went through if CURLOPT_FOLLOWLOCATION was set.

The main doc neglects to mention that when the CURLINFO_HEADER_OUT option is set the array returned by this function will included a new property, request_header, that is a string of the headers sent in the request.

A note about $curl_info['header_size'] (in response to the example above). 

Note that the total includes the size of any received headers suppressed by CURLOPT_SUPPRESS_CONNECT_HEADERS (see: https://curl.se/libcurl/c/CURLINFO_HEADER_SIZE.html) so if you are using a proxy which adds additional headers along with this option, $curl_info['header_size'] will give you the wrong string index based on the headers available in PHP. i.e., it will eat in to the start of the response instead of being the index of the beginning of the response.

If you use curl option CURLOPT_NOBODY = true to test if distant url is available, any sites can send you an http code 400 like Cdiscount Wsdl : 

$ch = @curl_init($wsdl);

if($ch === false)
    return false;
        
@curl_setopt($ch, CURLOPT_HEADER         ,true);    // we want headers
@curl_setopt($ch, CURLOPT_NOBODY         ,true);    // dont need body
@curl_setopt($ch, CURLOPT_RETURNTRANSFER ,true);    // catch output (do NOT print!)

@curl_exec($ch);

if(@curl_errno($ch)){   // should be 0
    @curl_close($ch);
    return false;
}

$code = @curl_getinfo($ch, CURLINFO_HTTP_CODE); 

Modifying CURLOPT_NOBODY to false, http code sent is 200 otherwise http code is 400 !!!

If you call curl_reset() on a handle that has already been passed to curl_exec(), and then perform a curl_getinfo() on the same handle, you may expect that you get the same result as if you called curl_getinfo() immediately after curl_init(). This is not the case, however. cURL will return the data from the previous execution. If you want to completely reset you actually need to unset the cURL handle and recreate a new one.

Keep in mind that for CURLOPT_RETURNTRANSFER it has to be set with curl_setopt() before execution:

This doesn't work:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
var_dump(curl_getinfo($ch,CURLINFO_HEADER_OUT));
?>

This works:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_exec($ch);
var_dump(curl_getinfo($ch,CURLINFO_HEADER_OUT));
?>
