tectonik's function works great and is exactly what i needed nevertheless it can only display
the navigator's version if it has a numeric format. Im using Firefox v 1.0.3 but it only
displayed 1.0 so I created a little function wich makes this function to display the correct
version.
<?
function validaContenido ( $cadena, $validacion )
{
$lCadena = strlen ( $cadena );
$lValidacion = strlen ( $validacion );
for ( $i = 0; $i < $lCadena; $i++ )
{
for ( $j = 0; $j < $lValidacion; $j++ )
{
if ( $cadena[$i] == $validacion[$j] )
break;
if ( ( $j == $lValidacion - 1 ) && ( $cadena[$i] != $validacion[$j] ) )
return false;
}
}
return true;
}
?>
now you use this function instead of is_numeric so the line will look like this:
<?
...
//if ( is_numeric ( $GLOBALS ["ver"] . $s ) )
if ( validaContenido ( $GLOBALS["ver"] . $s, ".0123456789" ) )
...
?>
Everything will end up looking like this:
<?
function validaContenido ( $cadena, $validacion )
{
$lCadena = strlen ( $cadena );
$lValidacion = strlen ( $validacion );
for ( $i = 0; $i < $lCadena; $i++ )
{
for ( $j = 0; $j < $lValidacion; $j++ )
{
if ( $cadena[$i] == $validacion[$j] )
break;
if ( ( $j == $lValidacion - 1 ) && ( $cadena[$i] != $validacion[$j] ) )
return false;
}
}
return true;
}
function detectaBrowser ()
{
$navegadores = "mozilla msie gecko firefox ";
$navegadores.= "konqueror safari netscape navigator ";
$navegadores.= "opera mosaic lynx amaya omniweb";
$arregloNavegadores = split ( " ", $navegadores );
$navegadorUsuario = strToLower( $_SERVER['HTTP_USER_AGENT'] );
$longitudNU = strlen( $navegadorUsuario );
for ( $i = 0; $i < count( $arregloNavegadores ); $i++ )
{
$navegador = $arregloNavegadores[$i];
$nombreNavegador = stristr( $navegadorUsuario, $navegador );
if ( strlen ( $nombreNavegador ) > 0 )
{
$info["ver"] = "";
$info["nav"] = $navegador;
$j = strpos ( $navegadorUsuario, $info["nav"] ) + $nombreNavegador + strlen (
$info["nav"] ) + 1;
for ( ; $j <= $longitudNU; $j++ )
{
$s = substr ( $navegadorUsuario, $j, 1);
if ( validaContenido ( $info["ver"] . $s, "0123456789." ) )
$info["ver"] .= $s;
else
break;
}
}
}
return $info;
}
?>
Now for example if you use a Firefox 1.0.3 browser it will display 1.0.3 instead of only 1.0
Hope it will be as useful for you as it was for me!
