1) Whois query using PHP -- use PHP to retrieve Whois requests

Using this code, you can obtain whois information in a specific domain name. Take the domain name as a parameter and display the relevant information of all domain names.

1. Function whois_query ($ domain ){
3. // Fix the domain name:
4. $ Domain = strtolower (trim ($ domain ));
5. $ Domain = preg_replace ('/^ http: \\// I', '', $ domain );
6. $ Domain = preg_replace ('/^ www \./I', '', $ domain );
7. $ Domain = explode ('/', $ domain );
8. $ Domain = trim ($ domain [0]);
10. // Split the TLD from domain name
11. $ _ Domain = explode ('.', $ domain );
12. $ Lst = count ($ _ domain)-1;
13. $ Ext = $ _ domain [$ lst];
15. // You find resources and lists
16. // Like these on wikipedia:
17. //
18. // Http://de.wikipedia.org/wiki/Whois </a>
19. //

62. If (! Isset ($ servers [$ ext]) {
63. Die ('Error: No matching nic server found! ');
64. }
66. $ Nic_server = $ servers [$ ext];
68. $ Output = '';
70. // Connect to whois server:
71. If ($ conn = fsockopen ($ nic_server, 43 )){
72. Fputs ($ conn, $ domain. "\ r \ n ");
73. While (! Feof ($ conn )){
74. $ Output. = fgets ($ conn, 128 );
75. }
76. Fclose ($ conn );
77. }

2. Require ('textmagic-sms-api-php/TextMagicAPI. php ');
4. // Set the username and password information
5. $ Username = 'myusername ';
6. $ Password = 'mypassword ';
8. // Create a new instance of TM
9. $ Router = new TextMagicAPI (array (
10. 'Username' => $ username,
11. 'Password' => $ password
12. ));
14. // Send a text message to '2017-123-4567'
15. $ Result = $ router-> send ('Wake up! ', Array (9991234567), true );
17. // Result: Result is: Array ([messages] => Array ([19896128] => 9991234567) [sent_text] => Wake up! [Parts_count] => 1)

3) Get info about your memory usage -- Get the memory usage code to help you Get the memory usage.

1. Echo "Initial:". memory_get_usage (). "bytes \ n ";
2. /* Prints
3. Initialize: 361400 bytes
4. */
6. // Let's use up some memory
7. For ($ I = 0; I I <100000; $ I ++ ){
8. $ Array [] = md5 ($ I );
9. }
11. // Let's remove half of the array
12. For ($ I = 0; I I <100000; $ I ++ ){
13. Unset ($ array [$ I]);
14. }
16. Echo "Final:". memory_get_usage (). "bytes \ n ";
17. /* Prints
18. Final: 885912 bytes
19. */
21. Echo "Peak:". memory_get_peak_usage (). "bytes \ n ";
22. /* Prints
23. Peak: 13687072 bytes
24. */

4) Display source code of any webpage -- view the source code of any web page

If you want to view the source code of the webpage, you only need to change the URL of the second line and the source code will be displayed on the webpage.

1. $ Line ){
2. // Loop thru each line and prepend line numbers
3. Echo "Line # {$ line_num}:". htmlspecialchars ($ line )."
4. \ N ";
5. }

1. Function data_uri ($ file, $ mime ){
2. $ Contents = file_get_contents ($ file );
3. $ Base64 = base64_encode ($ contents );
4. Echo "data: $ mime; base64, $ base64 ";
5. }

6) Detect location by IP -- retrieve the geographical location through IP

This code helps you find a specific IP address. you only need to enter an IP address in the function parameter to check the location.

1. Function detect_city ($ ip ){
3. $ Default = 'unknown ';
5. If (! Is_string ($ ip) | strlen ($ ip) <1 | $ ip = '2017. 0.0.1 '| $ ip = 'localhost') $ ip = '8. 8.8.8 '; $ curlopt_useragent = 'mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: 1.9.2) Gecko/20100115 Firefox/3.6 (. net clr 3.5.30729) '; $ url = 'http: // ipinfodb.com/ip_locator.php? Ip = '. urlencode ($ ip); $ ch = curl_init (); $ curl_opt = array (CURLOPT_FOLLOWLOCATION => 1,
6. CURLOPT_HEADER => 0,
7. CURLOPT_RETURNTRANSFER => 1,
8. CURLOPT_USERAGENT => $ curlopt_useragent,
9. CURLOPT_URL => $ url,
10. CURLOPT_TIMEOUT => 1,
11. CURLOPT_REFERER => 'http: // '. $ _ SERVER ['http _ host'],
12. );
14. Curl_setopt_array ($ ch, $ curl_opt );
16. $ Content = curl_exec ($ ch );
18. If (! Is_null ($ curl_info )){
19. $ Curl_info = curl_getinfo ($ ch );
20. }
22. Curl_close ($ ch );
24. If (preg_match ('{
25. City: ([^ <] *)
26. } I ', $ content, $ regs) {$ city = $ regs [1];} if (preg_match ('{
28. State/Province: ([^ <] *)
30. } I ', $ content, $ regs) {$ state = $ regs [1];} if ($ city! = "& $ State! = ") {$ Location = $ city. ','. $ state; return $ location;} else {return $ default ;}}

7) Detect browser language -- view the code script language used by the browser to Detect the browser.

1. Function get_client_language ($ availableLanguages, $ default = 'en '){
2. If (isset ($ _ SERVER ['http _ ACCEPT_LANGUAGE ']) {

5. Foreach ($ langs as $ value ){
6. $ Choice = substr ($ value, 0, 2 );
7. If (in_array ($ choice, $ availableLanguages )){
8. Return $ choice;
9. }
10. }
11. }
12. Return $ default;
13. }

8) Check if server is HTTPS -- Check whether the server is HTTPS

5. }
6. Rewind ($ handle );
7. While (! Feof ($ handle )){
8. $ Contents. = fread ($ handle, 8192 );
9. }
10. Fclose ($ handle );
