¿Cómo obtener el nombre y la versión exacta del navegador?

Question

He intentado algunas soluciones, pero no puedo obtener el nombre y la versión exactos:

Estoy intentando seguir el código:

$browserAgent = $_SERVER[''HTTP_USER_AGENT''];
echo $browserAgent;

Salida del código anterior:

Mozilla/5.0 (X11; Linux i686) AppleWebKit/534.24 (KHTML, like Gecko) Chrome/11.0.696.68 Safari/534.24

Pero estoy usando:

Google Chrome 11.0.696.68
on   
Ubuntu 10.04

Así que puedo encontrar en Chrome/11.0.696.68 en la cadena de salida pero también está mostrando algunos otros nombres de navegadores que son confusos para extraer el nombre exacto del navegador / versión de la cadena.

Answer 1

Me gustaría sugerirle esta clase increíble. Esto funcionó muy bien para mí.

Answer 3

Use get_browser()

De Manual:

echo $_SERVER[''HTTP_USER_AGENT''] . "/n/n";

$browser = get_browser(null, true);
print_r($browser);

Regresará:

Array
(
    [browser_name_regex] => ^mozilla/5/.0 (windows; .; windows nt 5/.1; .*rv:.*) gecko/.* firefox/0/.9.*$
    [browser_name_pattern] => Mozilla/5.0 (Windows; ?; Windows NT 5.1; *rv:*) Gecko/* Firefox/0.9*/

Answer 4

Use la función get_browser() .

Puede darte resultados como este:

Array
(
    [browser_name_regex] => ^mozilla/5/.0 (windows; .; windows nt 5/.1; .*rv:.*) gecko/.* firefox/0/.9.*$
    [browser_name_pattern] => Mozilla/5.0 (Windows; ?; Windows NT 5.1; *rv:*) Gecko/* Firefox/0.9*
    [parent] => Firefox 0.9
    [platform] => WinXP
    [browser] => Firefox
    [version] => 0.9
    [majorver] => 0
    [minorver] => 9
    .... 

Answer 5

Use la solución de detección de dispositivos 51Degrees.com para detectar el nombre del navegador, el proveedor y la versión.

Primero, siga la guía de 4 pasos para incorporar detector de dispositivo a su proyecto. Cuando digo incorporar me refiero a descargar el archivo con código PHP y archivo de base de datos, extraerlos e incluir 2 archivos. Eso es todo lo que hay que hacer para incorporar.

Una vez hecho esto, puede usar las siguientes propiedades para obtener información del navegador:
$_51d[''BrowserName''] - Le da el nombre del navegador (Safari, Molto, Motorola, MStarBrowser, etc.).
$_51d[''BrowserVendor''] - Le da la compañía que creó el navegador.
$_51d[''BrowserVersion''] - Número de versión del navegador

Hay un comment de AlexV en esta página, que habla sobre available .

Creo que esta es una gran clase y merece una respuesta propia. Lo acabo de usar y funciona como un amuleto (muy fácil de usar).

Answer 8

• Hay un conflicto entre (Safari) y (Opera) y (Chrome).

• Los códigos anteriores no pueden funcionar correctamente

Este es mi código, y funciona muy bien sin ningún conflicto:

function ExactBrowserName()
{

$ExactBrowserNameUA=$_SERVER[''HTTP_USER_AGENT''];

if (strpos(strtolower($ExactBrowserNameUA), "safari/") and strpos(strtolower($ExactBrowserNameUA), "opr/")) {
    // OPERA
    $ExactBrowserNameBR="Opera";
} elseIf (strpos(strtolower($ExactBrowserNameUA), "safari/") and strpos(strtolower($ExactBrowserNameUA), "chrome/")) {
    // CHROME
    $ExactBrowserNameBR="Chrome";
} elseIf (strpos(strtolower($ExactBrowserNameUA), "msie")) {
    // INTERNET EXPLORER
    $ExactBrowserNameBR="Internet Explorer";
} elseIf (strpos(strtolower($ExactBrowserNameUA), "firefox/")) {
    // FIREFOX
    $ExactBrowserNameBR="Firefox";
} elseIf (strpos(strtolower($ExactBrowserNameUA), "safari/") and strpos(strtolower($ExactBrowserNameUA), "opr/")==false and strpos(strtolower($ExactBrowserNameUA), "chrome/")==false) {
    // SAFARI
    $ExactBrowserNameBR="Safari";
} else {
    // OUT OF DATA
    $ExactBrowserNameBR="OUT OF DATA";
};

return $ExactBrowserNameBR;
}
