在開發 Web 或者行動裝置 App的時候,經常會遇到需要發送 SMS 給使用者,或者因為登入原因,或者是為了發送資訊。下面的 PHP 代碼就實現了發送 SMS 的功能。
為了使用任何的語言發送 SMS,需要一個 SMS gateway。大部分的 SMS 會提供一個 API,這裡是使用 MSG91 作為 SMS gateway。
function send_sms($mobile,$msg){$authKey = "XXXXXXXXXXX";date_default_timezone_set("Asia/Kolkata");$date = strftime("%Y-%m-%d %H:%M:%S");//Multiple mobiles numbers separated by comma$mobileNumber = $mobile; //Sender ID,While using route4 sender id should be 6 characters long.$senderId = "IKOONK"; //Your message to send, Add URL encoding here.$message = urlencode($msg); //Define route $route = "template";//Prepare you post parameters$postData = array( 'authkey' => $authKey, 'mobiles' => $mobileNumber, 'message' => $message, 'sender' => $senderId, 'route' => $route); //API URL$url="https://control.msg91.com/sendhttp.php"; // init the resource$ch = curl_init();curl_setopt_array($ch, array( CURLOPT_URL => $url, CURLOPT_RETURNTRANSFER => true, CURLOPT_POST => true, CURLOPT_POSTFIELDS => $postData //,CURLOPT_FOLLOWLOCATION => true)); //Ignore SSL certificate verificationcurl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); //get response$output = curl_exec($ch);//Print error if anyif(curl_errno($ch)){ echo 'error:' . curl_error($ch);} curl_close($ch);}
其中“$authKey = "XXXXXXXXXXX";”需要你輸入你的密碼,“$senderId = "IKOONK";”需要你輸入你的 SenderID。當輸入移動號碼的時候需要指定國家代碼 (比如,美國是 1,印度是 91 )。
文法:
<?php$message = "Hello World";$mobile = "918112998787";send_sms($mobile,$message);?>
2. 使用 mandrill 發送郵件
Mandrill 是一款強大的 SMTP 提供器。開發人員傾向於使用一個第三方 SMTP provider 來擷取更好的收件交付。
下面的函數中,你需要把 “Mandrill.php” 放在同一個檔案夾,作為 PHP 檔案,這樣就可以使用TA來發送郵件。
function send_email($to_email,$subject,$message1){require_once 'Mandrill.php';$apikey = 'XXXXXXXXXX'; //specify your api key here$mandrill = new Mandrill($apikey); $message = new stdClass();$message->html = $message1;$message->text = $message1;$message->subject = $subject;$message->from_email = "blog@koonk.com";//Sender Email$message->from_name = "KOONK";//Sender Name$message->to = array(array("email" => $to_email));$message->track_opens = true; $response = $mandrill->messages->send($message);}“$apikey = 'XXXXXXXXXX'; //specify your api key here”這裡需要你指定你的 API 金鑰(從 Mandrill 賬戶中獲得)。
文法:
<?php$to = "abc@example.com";$subject = "This is a test email";$message = "Hello World!";send_email($to,$subject,$message);?>
為了達到最好的效果,最好按照 Mandrill 的教程去配置 DNS。
3. PHP 函數:阻止 SQL 注入
SQL 注入或者 SQLi 常見的攻擊網站的手段,使用下面的代碼可以協助你防止這些注入。
function clean($input){ if (is_array($input)) { foreach ($input as $key => $val) { $output[$key] = clean($val); // $output[$key] = $this->clean($val); } } else { $output = (string) $input; // if magic quotes is on then use strip slashes if (get_magic_quotes_gpc()) { $output = stripslashes($output); } // $output = strip_tags($output); $output = htmlentities($output, ENT_QUOTES, 'UTF-8'); }// return the clean text return $output;
}
文法:
<?php$text = "<script>alert(1)</script>";$text = clean($text);echo $text;?>
4. 檢測使用者位置
使用下面的函數,可以檢測使用者是在哪個城市訪問你的網站。
function detect_city($ip) { $default = 'UNKNOWN'; $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 $default; } }
文法:
<?php$ip = $_SERVER['REMOTE_ADDR'];$city = detect_city($ip);echo $city;?>
5. 擷取 Web 頁面的原始碼
使用下面的函數,可以擷取任意 Web 頁面的 HTML 程式碼。
function display_sourcecode($url){$lines = file($url);$output = "";foreach ($lines as $line_num => $line) { // loop thru each line and prepend line numbers $output.= "Line #<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br>\n";}}文法:<?php$url = "http://blog.koonk.com";$source = display_sourcecode($url);echo $source;?>
6. 計算喜歡你的 Facebook 頁面的使用者
function fb_fan_count($facebook_name){ $data = json_decode(file_get_contents("https://graph.facebook.com/".$facebook_name)); $likes = $data->likes; return $likes;}
文法:
<?php$page = "koonktechnologies";$count = fb_fan_count($page);echo $count;?>
7. 確定任意圖片的主導顏色
function dominant_color($image){$i = imagecreatefromjpeg($image);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);}
8. whois 查詢
使用下面的函數可以擷取任何網域名稱使用者的完整細節。
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 $output;}
文法:
<?php$domain = "http://www.blog.koonk.com";$result = whois_query($domain);print_r($result);?>
9. 驗證郵箱地址
有時候,當在網站填寫表單,使用者可能會輸入錯誤的郵箱地址,這個函數可以驗證郵箱地址是否有效。
function is_validemail($email){$check = 0;if(filter_var($email,FILTER_VALIDATE_EMAIL)){$check = 1;}return $check;}
文法:
<?php$email = "blog@koonk.com";$check = is_validemail($email);echo $check;// If the output is 1, then email is valid.?>
10. 擷取使用者的真實 IP
function getRealIpAddr() { if (!emptyempty($_SERVER['HTTP_CLIENT_IP'])) { $ip=$_SERVER['HTTP_CLIENT_IP']; } elseif (!emptyempty($_SERVER['HTTP_X_FORWARDED_FOR'])) //to check ip is pass from proxy { $ip=$_SERVER['HTTP_X_FORWARDED_FOR']; } else { $ip=$_SERVER['REMOTE_ADDR']; } return $ip; }
文法:
<?php$ip = getRealIpAddr();echo $ip;?>
