  1. 傳送簡訊

  調用 TextMagic++ API。

  // Include the TextMagic PHP lib

  require('textmagic-sms-api-php/TextMagicAPI.php');

  // Set the username and password information

  $username = 'myusername';

  $password = 'mypassword';

  // Create a new instance of TM

  $router = new TextMagicAPI(array(

  'username' => $username,

  'password' => $password

  ));

  // Send a text message to '999-123-4567'

  $result = $router->send('Wake up!', array(9991234567), true);

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

 

  2. 根據IP尋找地址

  function detect_city($ip) {

  $default = 'UNKNOWN';

  if (!is_string($ip) strlen($ip) < 1 $ip == '127.0.0.1' $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. 顯示網頁的原始碼

  $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. 檢查伺服器是否使用HTTPS

  if ($_SERVER['HTTPS'] != "on") {

  echo "This is not HTTPS";

  }else{

  echo "This is HTTPS";

  }

 

  5. 顯示Facebook粉絲數量

  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. 檢測圖片的主要顏色

  $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. 擷取記憶體使用量資訊

  echo "Initial: ".memory_get_usage()." bytes \n";

  /* prints

  Initial: 361400 bytes

  */

  // let's use up some memory

  for ($i = 0; $i < 100000; $i++) {

  $array []= md5($i);

  }

  // let's remove half of the array

  for ($i = 0; $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. 使用 gzcompress() 壓縮資料

  $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 pretium orci,

  non ultricies elit lacus quis ante. Lorem ipsum dolor

  sit amet, consectetur adipiscing elit. Aliquam

  pretium ullamcorper 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. 使用PHP做Whois檢查

  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",

  "name" => "whois.nic.name",

  "net" => "whois.internic.net",

  "gov" => "whois.nic.gov",

  "edu" => "whois.internic.net",

  "mil" => "rs.internic.net",

  "int" => "whois.iana.org",

  "ac" => "whois.nic.ac",

  "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.to",

  "tv" => "whois.tv",

  "ru" => "whois.ripn.net",

  "org" => "whois.pir.org",

  "aero" => "whois.information.aero",

  "nl" => "whois.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: Could not connect to ' . $nic_server . '!'); }

  return $output;

  }

 

  10. 通過Email發送PHP錯誤

  // Our custom error handler

  function nettuts_error_handler($number, $message, $file, $line, $vars){

  $email = "

  

An error ($number) occurred on line

  $line and in the file: $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 than

  // just a NOTICE.

  if ( ($number !== E_NOTICE) && ($number < 2048) ) {

  die("There was an error. Please try again later.");

  }

  }

  // We should use our custom function to handle errors.

  set_error_handler('nettuts_error_handler');

  // Trigger an error... (var doesn't exist)

  echo $somevarthatdoesnotexist;
