分享几个非常有用的PHP代码片段

调用 TextMagic++ API。
  // Include the TextMagicPHP lib
  require('textmagic-sms-api-php/TextMagicAPI.php');
  // Set the username andpassword information
  $username = 'myusername';
  $password = 'mypassword';
  // Create a new instanceof 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. 根据IP查找地址
  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. 显示网页的源代码
  $lines = file('http://google.com/');
  foreach ($lines as$line_num => $line) {
  // loop thru each line and prepend line numbers
  echo "Line # {$line_num} : " . htmlspecialchars($line) . "
\n";
  }
  4. 检查服务器是否使用HTTPS
  if ($_SERVER['HTTPS']!= "on") {
  echo "This is not HTTPS";
  }else{
  echo "This is HTTPS";
  }
  5. 显示Faceboo易做图丝数量
  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. 检测图片的主要颜色
  $i = imagecreatefromjpeg("image.jpg");
  for ($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/$total);
  7. 获取内存使用信息
  echo "Initial:".memory_get_usage()." bytes \n";
  /* prints
  Initial: 361400 bytes
  */
  // let's use up some memory
  for ($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() 压缩数据
  $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 pretiumorci,
  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 justoin 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检查
  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 易做图:
  //
  // http://de.易做图.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
