Chilkat.Url

Parse a URL into its host, path, query, credentials, port, fragment, and TLS details.

Chilkat.Url is a focused URL parsing class. Given a full URL, it extracts the hostname, host type, login, password, path, query string, fragment, port, and SSL/TLS status into easy-to-read properties. It is useful when application code needs to inspect, validate, route, log, or pass URL parts to lower-level networking or API code.

Parse full URLs

Call ParseUrl to break a complete URL into structured properties that can be inspected individually.

Host and host type

Read the hostname and determine whether it is a DNS name, IPv4 address, or IPv6 address.

Path and query

Access the URL path, query string, and combined path-with-query value for request construction or routing.

Login and password

Extract embedded userinfo credentials when a URL contains a login and password component.

Port and TLS status

Determine the explicit or implied port and whether the URL represents an SSL/TLS connection.

Fragment handling

Read the URL fragment separately from the path and query for workflows that need anchor or client-side state information.

Common pattern: Use Url when the application needs to decompose a URL before making a request or applying custom logic. Parse the full URL, read the properties needed by the caller, then pass the relevant pieces to classes such as Chilkat.Http, Chilkat.Rest, or Chilkat.Socket. Use Url for parsing; use the higher-level networking classes to actually send the request.

Object Creation

use Chilkat2\Url;

try {
    $url = new Url();
    // ... use $url ...
} catch (\Chilkat2\Exception $e) {
    echo $e->getClass(), '::', $e->getMethod(), " failed\n";
    echo $e->getMessage(), "\n";              // the LastErrorText of the failed call
}
public function __construct(array $properties = [])

Creates the object. The optional array sets properties in order, as if assigned one by one (new Url(['VerboseLogging' => true, 'RaiseError' => false])); an unknown or read-only name throws Error. The class is defined by the chilkat2 extension (extension=chilkat2 in php.ini): there is no PHP file to include.

There is no close(): PHP frees the object when its last reference goes (unset($url), $url = null, or the end of the function or request). Objects returned by methods are independent and freed the same way. The class may be extended (class MyUrl extends \Chilkat2\Url); objects cannot be cloned or serialized.

public bool $RaiseError;

When true (the default), a method that fails throws Chilkat2\Exception. When false, it returns false (or null) instead, and the reason is in LastErrorText. Objects returned by a method inherit the value of the object that returned them.

Errors

Chilkat2\Exception extends RuntimeException: getMessage() is the failed call's full LastErrorText, getClass() its class ('Chilkat2\Url') and getMethod() the method name. The object remains usable. Methods that look something up and find nothing return null without throwing (each such method says so), methods that answer a question (HasMember, IsUnlocked, ...) return a plain bool, and property reads and writes do not throw for Chilkat reasons.

Misuse always throws, whatever RaiseError is: a wrong argument type is a TypeError (exact types under declare(strict_types=1)), a missing or extra argument an ArgumentCountError, a string containing a NUL byte or an out-of-range integer a ValueError, and an unknown property (properties are case-sensitive) or a write to a read-only one an Error. Named arguments work with the parameter names shown.

Strings are passed and returned as UTF-8; binary data is a PHP string of bytes. Unlocking: call (new \Chilkat2\GlobalSettings())->UnlockBundle('...') once at startup.

Properties

DebugLogFilePath
public string $DebugLogFilePath;

If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.

Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.

Possible causes of hangs include:

  • A timeout property set to 0, indicating an infinite timeout.
  • A hang occurring within an event callback in the application code.
  • An internal bug in the Chilkat code causing the hang.

More Information and Examples
top
Frag
public readonly string $Frag;
Introduced in version 9.5.0.49

Contains any text following a fragment marker (#) in the URL, excluding the fragment marker. Given the URI http://www.contoso.com/index.htm#main, the fragment is main.

top
Host
public readonly string $Host;
Introduced in version 9.5.0.49

The DNS host name or IP address part of the URL. For example, if the URL is http://www.contoso.com:8080/, the Host is www.contoso.com. If the URL is https://192.168.1.124/test.html, the Host is 192.168.1.124.

More Information and Examples
top
HostType
public readonly string $HostType;
Introduced in version 9.5.0.49

The type of the host name specified in the URL. Possible values are:

  • dns: The host name is a domain name system (DNS) style host name.
  • ipv4: The host name is an Internet Protocol (IP) version 4 host address.
  • ipv6: The host name is an Internet Protocol (IP) version 6 host address.

top
LastErrorHtml
public readonly string $LastErrorHtml;

Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastErrorText
public readonly string $LastErrorText;

Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastErrorXml
public readonly string $LastErrorXml;

Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastMethodSuccess
public bool $LastMethodSuccess;

Indicates the success or failure of the most recent method call: true means success, false means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages. Note: This property does not apply to methods that return integer values or to boolean-returning methods where the boolean does not indicate success or failure.

top
Login
public readonly string $Login;
Introduced in version 9.5.0.49

If the URL contains a login and password, this is the login part. For example, if the URL is http://user:password@www.contoso.com/index.htm , then the login is user.

top
Password
public readonly string $Password;
Introduced in version 9.5.0.49

If the URL contains a login and password, this is the password part. For example, if the URL is http://user:password@www.contoso.com/index.htm , then the password is password.

Methods

ParseUrl
public function ParseUrl(string $url): bool
Introduced in version 9.5.0.49

Parses a full URL. After parsing, the various parts of the URL are available iin the properties.

Returns true on success. On failure it throws Chilkat2\Exception (or, with RaiseError set to false, returns false). $e->getMessage() (or the object's LastErrorText) explains why, and the object remains usable.
