好東西要大家一起分享，上次分享了十個，這次再來十個超級有用的PHP代碼片段。

1. 發送短信

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('{<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. 顯示網頁的源代碼

<?php // display source code
$lines = file('http://google.com/');
foreach ($lines as $line_num => $line) {
// loop thru each line and prepend line numbers
echo "Line #<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br>n";
}
4. 檢查服務器是否使用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<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. 獲取內存使用信息

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() 壓縮數據

$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, $domain."rn"); 
    while(!feof($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

<?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>"; 
 
  $email .= "<pre>" . print_r($vars, 1) . "</pre>"; 
 
  $headers = 'Content-type: text/html; charset=iso-8859-1' . "rn"; 
 
  // 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; 

是不是也很精彩，和之前的一起收藏吧
