1. SMS 보내기

TextMagic API를 호출합니다.

// 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. IP를 기준으로 주소찾기

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)'; 
 
  $url = 'http://ipinfodb.com/ip_locator.php&#63;ip=' . urlencode($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('{<li>City : ([^<]*)</li>}i', $content, $regs) ) { 
   $city = $regs[1]; 
  } 
  if ( preg_match('{<li>State/Province : ([^<]*)</li>}i', $content, $regs) ) { 
   $state = $regs[1]; 
  } 
 
  if( $city!='' && $state!='' ){ 
   $location = $city . ', ' . $state; 
   return $location; 
  }else{ 
   return $default; 
  } 
 
 }

3. 웹페이지의 소스코드를 표시합니다

$lines = 파일('http://google.com/')
foreach ($lines as $line_num => $line) {
// 각 줄을 반복하고 줄 번호를 앞에 추가합니다
echo "라인 #{$line_num} : " . htmlspecialchars($line) "
n"; }

4. 서버가 HTTPS를 사용하는지 확인

if ($_SERVER['HTTPS'] != "on") { 
 echo "This is not HTTPS"; 
}else{ 
 echo "This is HTTPS"; 
}

5. 페이스북 팬 수 표시

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. 이미지의 메인 컬러를 감지합니다

$i = imagecreatefromjpeg("image.jpg"); 
 
for ($x=0;$x<imagesx($i);$x++) { 
 for ($y=0;$y<imagesy($i);$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. 메모리 사용량 정보 확인

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. gzcompress()를 사용하여 데이터 압축

$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. PHP를 사용하여 Whois 확인

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",

 ); 
 
 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. 이메일로 PHP 오류 보내기

<&#63;php 
 
// Our custom error handler 
function nettuts_error_handler($number, $message, $file, $line, $vars){ 
 $email = " 
  <p>An error ($number) occurred on line 
  <strong>$line</strong> and in the <strong>file: $file.</strong> 
  <p> $message </p>"; 
 
 $email .= "<pre class="brush:php;toolbar:false">" . print_r($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;
