PHP代码片段（发送短信、根据IP查找地址、显示网页的源代码、检查服务器是否使用HTTPS、显示Faceboo**丝数量、检测图片的主要颜色、获取内存使用信息）

1. 发送短信
调用 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. 根据IP查找地址

function detect_city($ip) {

$default = 'UNKNOWN';

if (!is_string($ip) || strlen($ip)  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 $line) { // loop thru each line and prepend line numbers echo "Line #{$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**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> 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/$total); 7. 获取内存使用信息 echo"Initial: ".memory_get_usage()." bytes \n"; /* prints Initial: 361400 bytes */ // http://www.baoluowanxiang.com/ // let's use up some memory for ($i = 0; $i "whois.neulevel.biz", "com" => "whois.internic.net", "us" => "whois.nic.us", "coop" => "whois.nic.coop", "info" => "whois.nic.info", "name" => "whois.nic.name", "net" => "whois.internic.net", "gov" => "whois.nic.gov", "edu" => "whois.internic.net", "mil" => "rs.internic.net", "int" => "whois.iana.org", "ac" => "whois.nic.ac", "ae" => "whois.uaenic.ae", "at" => "whois.ripe.net", "au" => "whois.aunic.net", "be" => "whois.dns.be", "bg" => "whois.ripe.net", "br" => "whois.registro.br", "bz" => "whois.belizenic.bz", "ca" => "whois.cira.ca", "cc" => "whois.nic.cc", "ch" => "whois.nic.ch", "cl" => "whois.nic.cl", "cn" => "whois.cnnic.net.cn", "cz" => "whois.nic.cz", "de" => "whois.nic.de", "fr" => "whois.nic.fr", "hu" => "whois.nic.hu", "ie" => "whois.domainregistry.ie", "il" => "whois.isoc.org.il", "in" => "whois.ncst.ernet.in", "ir" => "whois.nic.ir", "mc" => "whois.ripe.net", "to" => "whois.tonic.to", "tv" => "whois.tv", "ru" => "whois.ripn.net", "org" => "whois.pir.org", "aero" => "whois.information.aero", "nl" => "whois.domain-registry.nl" ); if (!isset($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 $output; } 10. 通过Email发送PHP错误 An error ($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
