// Result: Result is: Array ([messages] => Array ([19896128] => 9991234567) [sent_text] => Wake up! [Parts_count] => 1)


2. search for an IP address

Function detect_city ($ ip ){

$ Default = 'unknown ';

If (! Is_string ($ ip) | strlen ($ ip) <1 | $ ip = '192. 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,
CURLOPT_HEADER => 0,
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_USERAGENT => $ curlopt_useragent,
CURLOPT_URL => $ url,
CURLOPT_TIMEOUT => 1,
CURLOPT_REFERER => 'http: // '. $ _ SERVER ['http _ host'],
);

Curl_setopt_array ($ ch, $ curl_opt );

$ Content = curl_exec ($ ch );

If (! Is_null ($ curl_info )){
$ Curl_info = curl_getinfo ($ ch );
}

Curl_close ($ ch );

If (preg_match ('{

  • City: ([^ <] *)
  • } I ', $ content, $ regs )){
    $ City = $ regs [1];
    }
    If (preg_match ('{
  • State/Province: ([^ <] *)
  • } I ', $ content, $ regs )){
    $ State = $ regs [1];
    }

    If ($ city! = ''& $ State! = ''){
    $ Location = $ city. ','. $ state;
    Return $ location;
    } Else {
    Return $ default;
    }

    }


    3. display the source code of the webpage

    $ Lines = file ('http: // google.com /');
    Foreach ($ lines as $ line_num => $ line ){
    // Loop thru each line and prepend line numbers
    Echo "Line # {$ Line_num}: ". Htmlspecialchars ($ line )."
    \ N ";
    }


    4. check whether the server uses HTTPS

    If ($ _ SERVER ['https']! = "On "){
    Echo "This is not HTTPS ";
    } Else {
    Echo "This is HTTPS ";
    }


    5. display Faceboo ** Number of filaments

    Function fb_fan_count ($ facebook_name ){
    // Example: https://graph.facebook.com/digimantra
    $ Data = json_decode (file_get_contents ("https://graph.facebook.com/". $ facebook_name ));
    Echo $ data-> likes;
    }


    6. check the main color of the image.

    $ I = imagecreatefromjpeg ("image.jpg ");

    For ($ x = 0; $ x For ($ y = 0; $ y $ Rgb = imagecolorat ($ I, $ x, $ y );
    $ R = ($ rgb> 16) & 0xFF;
    $ G = ($ rgb >>& 0xFF;
    $ B = $ rgb & 0xFF;

    $ RTotal + = $ r;
    $ GTotal + = $ g;
    $ BTotal + = $ B;
    $ Total ++;
    }
    }

    $ RAverage = round ($ rTotal/$ total );
    $ GAverage = round ($ gTotal/$ total );
    $ BAverage = round ($ bTotal/$ total );


    7. get memory usage information

    Echo "Initial:". memory_get_usage (). "bytes \ n ";
    /* Prints
    Initialize: 361400 bytes
    */
    // Http://www.baoluowanxiang.com/
    // Let's use up some memory
    For ($ I = 0; I I <100000; $ I ++ ){
    $ Array [] = md5 ($ I );
    }

    // Let's remove half of the array
    For ($ I = 0; I I <100000; $ I ++ ){
    Unset ($ array [$ I]);
    }

    Echo "Final:". memory_get_usage (). "bytes \ n ";
    /* Prints
    Final: 885912 bytes
    */

    Echo "Peak:". memory_get_peak_usage (). "bytes \ n ";
    /* Prints
    Peak: 13687072 bytes
    */


    8. use gzcompress () to compress data

    $ String =
    "Lorem ipsum dolor sit amet, consectetur
    Adipiscing elit. Nunc ut elit id mi ultricies
    Adipiscing. Nulla facilisi. Praesent pulvinar,
    Sapien vel feugiat vestibulum, nulla dui presponorci,
    Non ultricies elit lacus quis ante. Lorem ipsum dolor
    Sit amet, consectetur adipiscing elit. Aliquam
    Prepolicullamcorper urna quis iaculis. Etiam ac massa
    Sed turpis tempor luctus. Curabitur sed nibh eu elit
    Mollis congue. Praesent ipsum diam, consectetur vitae
    Ornare a, aliquam a nunc. In id magna pellentesque
    Tellus posuere adipiscing. Sed non mi metus, at lacinia
    Augue. Sed magna nisi, ornare in mollis in, mollis
    Sed nunc. Etiam at justo in leo congue mollis.
    Nullam in neque eget metus hendrerit scelerisque
    Eu non enim. Ut malesuada lacus eu nulla bibendum
    Id euismod urna sodales .";

    $ Compressed = gzcompress ($ string );

    Echo "Original size:". strlen ($ string). "\ n ";
    /* Prints
    Original size: 800
    */

    Echo "Compressed size:". strlen ($ compressed). "\ n ";
    /* Prints
    Compressed size: 418
    */

    // Getting it back
    $ Original = gzuncompress ($ compressed );


    9. use PHP for Whois check

    Function whois_query ($ domain ){

    // Fix the domain name:
    $ Domain = strtolower (trim ($ domain ));
    $ Domain = preg_replace ('/^ http: \\// I', '', $ domain );
    $ Domain = preg_replace ('/^ www \./I', '', $ domain );
    $ Domain = explode ('/', $ domain );
    $ Domain = trim ($ domain [0]);

    // Split the TLD from domain name
    $ _ Domain = explode ('.', $ domain );
    $ Lst = count ($ _ domain)-1;
    $ Ext = $ _ domain [$ lst];

    // You find resources and lists
    // Like these on wikipedia:
    //
    // Http://de.wikipedia.org/wiki/Whois
    //
    $ Servers = array (
    "Biz" => "whois. neulevel. biz ",
    "Com" => "whois.internic.net ",
    "Us" => "whois. nic. us ",
    "Coop" => "whois. nic. coop ",
    "Info" => "whois.nic.info ",

    "AE" => "whois. uaenic. AE ",
    "At" => "whois.ripe.net ",
    "Au" => "whois.aunic.net ",
    "Be" => "whois. dns. be ",
    "Bg" => "whois.ripe.net ",
    "Br" => "whois.registro.br ",
    "Bz" => "whois. belizenic. bz ",
    "Ca" => "whois. cira. ca ",
    "Cc" => "whois. nic. cc ",
    "Ch" => "whois. nic. ch ",
    "Cl" => "whois. nic. cl ",
    "Cn" => "whois.cnnic.net.cn ",
    "Cz" => "whois. nic. cz ",
    "De" => "whois.nic.de ",
    "Fr" => "whois. nic. fr ",
    "Hu" => "whois. nic. hu ",
    "Ie" => "whois. domainregistry. ie ",
    "Il" => "whois.isoc.org. il ",
    "In" => "whois. ncst. ernet. in ",
    "Ir" => "whois. nic. ir ",
    "Mc" => "whois.ripe.net ",
    "To" => "whois. tonic. ",
    "TV" => "whois. TV ",
    "Ru" => "whois.ripn.net ",
    "Org" => "whois.pir.org ",
    "Aero" => "whois. information. aero ",
    "Nl" => "whais. domain-registry.nl"
    );

    If (! Isset ($ servers [$ ext]) {
    Die ('Error: No matching nic server found! ');
    }

    $ Nic_server = $ servers [$ ext];

    $ Output = '';

    // Connect to whois server:
    If ($ conn = fsockopen ($ nic_server, 43 )){
    Fputs ($ conn, $ domain. "\ r \ n ");
    While (! Feof ($ conn )){
    $ Output. = fgets ($ conn, 128 );
    }
    Fclose ($ conn );
    }
    Else {die ('Error: cocould not connect to '. $ nic_server .'! ');}

    Return $ output;
    }


    10. sending PHP errors via Email


    // Our custom error handler
    Function nettuts_error_handler ($ number, $ message, $ file, $ line, $ vars ){
    $ Email ="

    An error ($ number) occurred on line
    $ LineAnd inFile: $ file.

    $ Message

    ";

    $ Email. ="
    " . print_r($vars, 1) . "
    ";

    $ Headers = 'content-type: text/html; charset = ISO-8859-1 '. "\ r \ n ";

    // Email the error to someone...
    Error_log ($ email, 1, 'you @ youremail.com', $ headers );

    // Make sure that you decide how to respond to errors (on the user's side)
    // Either echo an error message, or kill the entire project. Up to you...
    // The code below ensures that we only "die" if the error was more
    // Just a NOTICE.
    If ($ number! ==E_notice) & ($ number <2048 )){
    Die ("There was an error. Please try again later .");
    }
    }

    // We shoshould use our custom function to handle errors.
    Set_error_handler ('nettuts _ error_handler ');

    // Trigger an error... (var doesn't exist)
    Echo $ somevarthatdoesnotexist;
