###############################################################################
#### Create a URL UrlInfo instances from existing URLs

// URL with hostname
$url = 'http://hostname.tld/';
$urlInfo = new mpUrlInfo($url);
echo (string) $urlInfo . "\n";

// URL with hostname and path
$url = 'http://hostname.tld/path/to/page/';
$urlInfo = new mpUrlInfo($url);
echo (string) $urlInfo . "\n";

// URL with hostname, path and query parameter
$url = 'http://hostname.tld/path/to/page/?foo=bar&amp;num=123';
$urlInfo = new mpUrlInfo($url);
echo (string) $urlInfo . "\n";

// URL with hostname, path, query parameter and fragment
$url = 'http://hostname.tld/path/to/page/?foo=bar&amp;num=123#content_xy';
$urlInfo = new mpUrlInfo($url);
echo (string) $urlInfo . "\n";


###############################################################################
#### Build URL UrlInfo from scratch

$urlInfo = new mpUrlInfo();
$urlInfo->setScheme('http');
$urlInfo->setHost('hostname.tld');
$urlInfo->setPath('/path/to/page.html');
$urlInfo->setQueryParameter('foo', 'bar');
$urlInfo->setQueryParameter('num', '123');
$urlInfo->setFragment('content_xy');
echo (string) $urlInfo . "\n";


###############################################################################
#### Examples for usage of equals() method.

// sample URL
$url = 'http://hostname.tld/path?foo=bar&num=123';
$urlInfo = new mpUrlInfo($url);

// check, if $urlInfo equals itself
if ($urlInfo->equals($urlInfo)) {
    echo (string) $urlInfo . " equals " . (string) $urlInfo . "\n";
} else {
    echo (string) $urlInfo . " don't equals " . (string) $urlInfo . "\n";
}

// check, if $urlInfo equals a clone
$urlInfo2 = clone $urlInfo;
if ($urlInfo->equals($urlInfo2)) {
    echo (string) $urlInfo . " equals " . (string) $urlInfo2 . "\n";
} else {
    echo (string) $urlInfo . " don't equals " . (string) $urlInfo2 . "\n";
}

// check, if $urlInfo equals a new instance
$urlInfo2 = new mpUrlInfo($url);
if ($urlInfo->equals($urlInfo2)) {
    echo (string) $urlInfo . " equals " . (string) $urlInfo2 . "\n";
} else {
    echo (string) $urlInfo . " don't equals " . (string) $urlInfo2 . "\n";
}


###############################################################################
#### Examples for usage of isSameUrl() method.

// sample URL
$url = 'http://hostname.tld/path?foo=bar&num=123';
$urlInfo = new mpUrlInfo($url);

// check, if $urlInfo is the same as itself
if ($urlInfo->isSameUrl($urlInfo)) {
    echo (string) $urlInfo . " is same as " . (string) $urlInfo . "\n";
} else {
    echo (string) $urlInfo . " isn't same as  " . (string) $urlInfo . "\n";
}

// check, if $urlInfo is the same as new one which is identical except for additional fragment
$url = 'http://hostname.tld/path?foo=bar&num=123#content_xy';
$urlInfo2 = new mpUrlInfo($url);
if ($urlInfo->isSameUrl($urlInfo2)) {
    echo (string) $urlInfo . " is same as " . (string) $urlInfo2 . "\n";
} else {
    echo (string) $urlInfo . " isn't same as  " . (string) $urlInfo2 . "\n";
}

// another example with different argument separator (uses '&amp;' instead of '&')
$url = 'http://hostname.tld/path?foo=bar&amp;num=123#content_xy';
$urlInfo2 = new mpUrlInfo($url);
if ($urlInfo->isSameUrl($urlInfo2)) {
    echo (string) $urlInfo . " is same as " . (string) $urlInfo2 . "\n";
} else {
    echo (string) $urlInfo . " isn't same as  " . (string) $urlInfo2 . "\n";
}


###############################################################################
#### Examples for usage of arguments separator methods.

// NOTE: A defined arguments separator takes allways precedence over existing 
//       arguments separator in source URLs

// save current arguments separator, it's '&amp;' by default
$argSeparator = mpUrlInfo::getArgSeparator();

// set new arguments separator
mpUrlInfo::setArgSeparator('&');

// sample url
$url = 'http://hostname.tld/path?foo=bar&num=123';
$urlInfo = new mpUrlInfo($url);
echo (string) $urlInfo . "\n";

// another sample url
$url = '/path?foo=bar&num=123&param3=valueX';
$urlInfo = new mpUrlInfo($url);
echo (string) $urlInfo . "\n";

// restore original arguments separator
mpUrlInfo::setArgSeparator($argSeparator);


###############################################################################
#### Example for setUrl() method.

$urlInfo = new mpUrlInfo();

$url = 'http://hostname.tld/path?foo=bar&amp;num[]=123&amp;num[]=124&amp;num[]=125';
$urlInfo->setUrl($url);
echo (string) $urlInfo . "\n";


###############################################################################
#### Examples for trimPath() method.

// NOTE: Trim path returns the path cleaned from beginning or ending slashes '/'

$path = mpUrlInfo::trimPath('/path/to/page/');
echo $path . "\n";

$path = mpUrlInfo::trimPath('path/to/page/');
echo $path . "\n";

$path = mpUrlInfo::trimPath('path/to/page');
echo $path . "\n";


###############################################################################
#### Examples for setQueryParameter() method.

$url = 'http://hostname.tld/path';
$urlInfo = new mpUrlInfo($url);

// several query parameter
$urlInfo->setQueryParameter('foo', 'bar');
$urlInfo->setQueryParameter('num', '123');
$query = $urlInfo->getQuery();
echo $query . "\n";

// query parameter as array
$params = array('valueOf_0', 'valueOf_1', 'valueOf_2');
$urlInfo->setQueryParameter('multiple', $params);
$query = $urlInfo->getQuery();
echo $query . "\n";


###############################################################################
#### Examples for setScheme() method.

// NOTE: Only schemes 'http', 'https' and 'ftp' are supported

$urlInfo = new mpUrlInfo();

$urlInfo->setScheme('http');
echo $urlInfo->getScheme() . "\n";

$urlInfo->setScheme('HTTP');
echo $urlInfo->getScheme() . "\n";

$urlInfo->setScheme('https');
echo $urlInfo->getScheme() . "\n";

$urlInfo->setScheme('ftp');
echo $urlInfo->getScheme() . "\n";

// set empty scheme to cause an error
try {
    $urlInfo->setScheme('');
} catch (Exception $e) {
    // exception handling
    echo $e->getMessage() . "\n";
}

// set a not supported scheme to cause an error
try {
    $urlInfo->setScheme('asdf');
} catch (Exception $e) {
    // exception handling
    echo $e->getMessage() . "\n";
}


###############################################################################
#### Examples for setHost() method.

$urlInfo = new mpUrlInfo();

$urlInfo->setHost('foobar');
echo $urlInfo->getHost() . "\n";

// set a empty host to cause an error
try {
    $urlInfo->setHost('');
} catch (Exception $e) {
    // exception handling
    echo $e->getMessage() . "\n";
}


###############################################################################
#### Examples for setPort() method.

$urlInfo = new mpUrlInfo();

$urlInfo->setPort('12345');
echo $urlInfo->getPort() . "\n";

$urlInfo->setPort(80);
echo $urlInfo->getPort() . "\n";

// set a empty port to cause an error
try {
    $urlInfo->setPort('');
} catch (Exception $e) {
    // exception handling
    echo $e->getMessage() . "\n";
}

// set a invalid port to cause an error

###############################################################################
#### Examples for setPass() method.

$urlInfo = new mpUrlInfo();

$urlInfo->setPass('open sesame');

$urlInfo->setFilename('page.html');
echo $urlInfo->getFilename() . "\n";

// no filename of a path with ending slash
$urlInfo->setPath('/path/to/page/');
echo $urlInfo->getFilename() . "\n";

// path without ending slash returns the last item as filename
$urlInfo->setPath('/path/to/page');
echo $urlInfo->getFilename() . "\n"; // should echo 'page'


###############################################################################
