Como detectar que navegador usas con PHP:
Código PHP:
<?php
function browser_detection( $which_test ) {
// initialize the variables
$browser = '';
$dom_browser = '';
// set to lower case to avoid errors, check to see if http_user_agent is set
$navigator_user_agent = ( isset( $_SERVER['HTTP_USER_AGENT'] ) ) ? strtolower( $_SERVER['HTTP_USER_AGENT'] ) : '';
// run through the main browser possibilities, assign them to the main $browser variable
if (stristr($navigator_user_agent, "opera"))
{
$browser = 'opera';
$dom_browser = true;
}
elseif (stristr($navigator_user_agent, "msie 4"))
{
$browser = 'msie4';
$dom_browser = false;
}
elseif (stristr($navigator_user_agent, "msie"))
{
$browser = 'msie';
$dom_browser = true;
}
elseif ((stristr($navigator_user_agent, "konqueror")) || (stristr($navigator_user_agent, "safari")))
{
$browser = 'safari';
$dom_browser = true;
}
elseif (stristr($navigator_user_agent, "gecko"))
{
$browser = 'mozilla';
$dom_browser = true;
}
elseif (stristr($navigator_user_agent, "mozilla/4"))
{
$browser = 'ns4';
$dom_browser = false;
}
else
{
$dom_browser = false;
$browser = false;
}
// return the test result you want
if ( $which_test == 'browser' )
{
return $browser;
}
elseif ( $which_test == 'dom' )
{
return $dom_browser;
// note: $dom_browser is a boolean value, true/false, so you can just test if
// it's true or not.
}
}
/*
you would call it like this:
$user_browser = browser_detection('browser');
if ( $user_browser == 'opera' )
{
do something;
}
or like this:
if ( browser_detection('dom') )
{
execute the code for dom browsers
}
else
{
execute the code for non DOM browsers
}
and so on.......
