How to Get Current Page URL, Domain, Query String in PHP

In this tutorial, We would love to share with you, How to get current page URL in PHP, PHP get current URL path, PHP get full URL with parameters, PHP get a current page, PHP get current URL with query string, PHP get a domain from URL.

How to Get Current Page URL in PHP

Here you will discuss about superglobal variable $_SERVER, this is built-in PHP variable. We will use this variable get the current page URL in PHP. You can get every piece of information about the current URL using the $_SERVER superglobal.

Before we try to fetch the Current Page Full URL lets see how a normal URL structure looks like:

http://www.abc.com/dir1/test.php?glob=hello&name=world

Any typical URL like this can be broken into several common parts like:

• HTTP: The URL protocol
• www.abc.com – The domain name or the hostname.
• dir1: The directory within the root
• test.php – The actual PHP script
• glob=hello – the first URL parameter (glob) and it’s a value (hello)
• name=world – the second URL parameter (name) and its value (world)

Now we will create a program that is used to get current page url.

Other Important elements of $_SERVER that are very are useful and you must know that:

• $_SERVER[‘SERVER_ADDR’]: IP address of the server
• $_SERVER[‘REQUEST_METHOD’]: Returns the page access method used i.e. ‘GET’, ‘HEAD’, ‘POST’, ‘PUT’.
• $_SERVER[‘REQUEST_TIME’]: timestamp of the start of the request.
• $_SERVER[‘HTTP_REFERER’]: returns the referrer page uri – used in redirecting to last page after login
• $_SERVER[‘SCRIPT_FILENAME’]: returns the path including the filename, like DIR
• $_SERVER[‘HTTP_COOKIE’]. returns the raw value of the ‘Cookie’ header sent by the user agent.
• $_SERVER[‘HTTP_ACCEPT_LANGUAGE’]): returns the default set language – useful for websites with multilingual content & readers
• $_SERVER[‘HTTP_USER_AGENT’]: returns the kind of device being used to access (desktop/mobile device etc) – suitable for switching interface for different devices.

$_SERVER

$_SERVER is an array containing information such as headers, paths, and script locations. The entries in this array are created by the web server, therefore there is no guarantee that every web server will provide any of these; servers may omit some, or provide others not listed here. However, most of these variables are accounted for in the » CGI/1.1 specification, and are likely to be defined.

Note: When running PHP on the command line most of these entries will not be available or have any meaning.

In addition to the elements listed below, PHP will create additional elements with values from request headers. These entries will be named HTTP_ followed by the header name, capitalized and with underscores instead of hyphens. For example, the Accept-Language header would be available as $_SERVER[‘HTTP_ACCEPT_LANGUAGE’] .

Indices

‘ PHP_SELF ‘ The filename of the currently executing script, relative to the document root. For instance, $_SERVER[‘PHP_SELF’] in a script at the address http://example.com/foo/bar.php would be /foo/bar.php . The __FILE__ constant contains the full path and filename of the current (i.e. included) file. If PHP is running as a command-line processor this variable contains the script name. ‘argv’ Array of arguments passed to the script. When the script is run on the command line, this gives C-style access to the command line parameters. When called via the GET method, this will contain the query string. ‘argc’ Contains the number of command line parameters passed to the script (if run on the command line). ‘ GATEWAY_INTERFACE ‘ What revision of the CGI specification the server is using; e.g. ‘CGI/1.1’ . ‘ SERVER_ADDR ‘ The IP address of the server under which the current script is executing. ‘ SERVER_NAME ‘ The name of the server host under which the current script is executing. If the script is running on a virtual host, this will be the value defined for that virtual host.

Note: Under Apache 2, UseCanonicalName = On and ServerName must be set. Otherwise, this value reflects the hostname supplied by the client, which can be spoofed. It is not safe to rely on this value in security-dependent contexts.

‘ SERVER_SOFTWARE ‘ Server identification string, given in the headers when responding to requests. ‘ SERVER_PROTOCOL ‘ Name and revision of the information protocol via which the page was requested; e.g. ‘HTTP/1.0’ ; ‘ REQUEST_METHOD ‘ Which request method was used to access the page; e.g. ‘GET’ , ‘HEAD’ , ‘POST’ , ‘PUT’ .

Note:

PHP script is terminated after sending headers (it means after producing any output without output buffering) if the request method was HEAD .

‘ REQUEST_TIME ‘ The timestamp of the start of the request. ‘ REQUEST_TIME_FLOAT ‘ The timestamp of the start of the request, with microsecond precision. ‘ QUERY_STRING ‘ The query string, if any, via which the page was accessed. ‘ DOCUMENT_ROOT ‘ The document root directory under which the current script is executing, as defined in the server’s configuration file. ‘ HTTPS ‘ Set to a non-empty value if the script was queried through the HTTPS protocol. ‘ REMOTE_ADDR ‘ The IP address from which the user is viewing the current page. ‘ REMOTE_HOST ‘ The Host name from which the user is viewing the current page. The reverse dns lookup is based on the REMOTE_ADDR of the user.

Note: The web server must be configured to create this variable. For example in Apache HostnameLookups On must be set inside httpd.conf for it to exist. See also gethostbyaddr() .

‘ REMOTE_PORT ‘ The port being used on the user’s machine to communicate with the web server. ‘ REMOTE_USER ‘ The authenticated user. ‘ REDIRECT_REMOTE_USER ‘ The authenticated user if the request is internally redirected. ‘ SCRIPT_FILENAME ‘

The absolute pathname of the currently executing script.

Note:

If a script is executed with the CLI, as a relative path, such as file.php or ../file.php , $_SERVER[‘SCRIPT_FILENAME’] will contain the relative path specified by the user.

‘ SERVER_ADMIN ‘ The value given to the SERVER_ADMIN (for Apache) directive in the web server configuration file. If the script is running on a virtual host, this will be the value defined for that virtual host. ‘ SERVER_PORT ‘ The port on the server machine being used by the web server for communication. For default setups, this will be ’80’ ; using SSL, for instance, will change this to whatever your defined secure HTTP port is.

Note: Under Apache 2, UseCanonicalName = On , as well as UseCanonicalPhysicalPort = On must be set in order to get the physical (real) port, otherwise, this value can be spoofed, and it may or may not return the physical port value. It is not safe to rely on this value in security-dependent contexts.

‘ SERVER_SIGNATURE ‘ String containing the server version and virtual host name which are added to server-generated pages, if enabled. ‘ PATH_TRANSLATED ‘ Filesystem- (not document root-) based path to the current script, after the server has done any virtual-to-real mapping.

Note: Apache 2 users may use AcceptPathInfo = On inside httpd.conf to define PATH_INFO .

‘ SCRIPT_NAME ‘ Contains the current script’s path. This is useful for pages which need to point to themselves. The __FILE__ constant contains the full path and filename of the current (i.e. included) file. ‘ REQUEST_URI ‘ The URI which was given in order to access this page; for instance, ‘ /index.html ‘. ‘ PHP_AUTH_DIGEST ‘ When doing Digest HTTP authentication this variable is set to the ‘Authorization’ header sent by the client (which you should then use to make the appropriate validation). ‘ PHP_AUTH_USER ‘ When doing HTTP authentication this variable is set to the username provided by the user. ‘ PHP_AUTH_PW ‘ When doing HTTP authentication this variable is set to the password provided by the user. ‘ AUTH_TYPE ‘ When doing HTTP authentication this variable is set to the authentication type. ‘ PATH_INFO ‘ Contains any client-provided pathname information trailing the actual script filename but preceding the query string, if available. For instance, if the current script was accessed via the URI http://www.example.com/php/path_info.php/some/stuff?foo=bar , then $_SERVER[‘PATH_INFO’] would contain /some/stuff . ‘ ORIG_PATH_INFO ‘ Original version of ‘ PATH_INFO ‘ before processed by PHP.

PHP is a popular programming language used for web development. One common task in PHP is getting the current page name. In this article, we will explore various ways to get the current page name in PHP.

Using $_SERVER[«PHP_SELF»]

$_SERVER is a superglobal variable that provides information about the server environment. $_SERVER[«PHP_SELF»] provides the current filename and its path. basename() can be used to get just the filename from the path provided by $_SERVER[«PHP_SELF»] .

$filename = basename($_SERVER["PHP_SELF"]); 

In the above code, $filename would contain the name of the current page.

Using $_SERVER[«REQUEST_URI»]

$_SERVER[«REQUEST_URI»] provides the file with GET parameters and includes folders in the URL. This method can be used to get the full URL of the current page.

$pageUrl = $_SERVER["REQUEST_URI"]; 

In the above code, $pageUrl would contain the full URL of the current page.

Using parse_url($_SERVER[’HTTP_REFERER’],PHP_URL_PATH)

$_SERVER[‘HTTP_REFERER’] provides the previous page URL. parse_url($_SERVER[‘HTTP_REFERER’],PHP_URL_PATH) can be used to get the previous page name in PHP.

$previousPage = basename(parse_url($_SERVER['HTTP_REFERER'],PHP_URL_PATH)); 

In the above code, $previousPage would contain the name of the previous page.

Using $_SERVER[’SCRIPT_NAME’]

$_SERVER[‘SCRIPT_NAME’] can be used to get the current file name.

$pageName = basename($_SERVER['SCRIPT_NAME']); 

In the above code, $pageName would contain the name of the current page.

Using pathinfo() function

pathinfo() function can be used to get an array with details about a path.

$path_parts = pathinfo('/www/htdocs/inc/lib.inc.php'); $pageName = $path_parts['basename']; 

In the above code, $pageName would contain the name of the current page.

Other examples of quick code snippets to get the page name in PHP

In Php , in particular, how to get page name in php code sample

echo basename($_SERVER['PHP_SELF']); /* Returns The Current PHP File Name */ 

Conclusion
