在开发 web 或者移动应用的时候，经常会遇到需要发送 sms 给用户，或者因为登录原因，或者是为了发送信息。下面的 php 代码就实现了发送 sms 的功能。
为了使用任何的语言发送 sms，需要一个 sms gateway。大部分的 sms 会提供一个 api，这里是使用 msg91 作为 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“$authkey = "xxxxxxxxxxx";”需要你输入你的密码，“$senderid = "ikoonk";”需要你输入你的 senderid。当输入移动号码的时候需要指定国家代码 (比如，美国是 1，印度是 91 )。
语法：
<?php$message = "hello world";$mobile = "918112998787"; send_sms($mobile,$message);?>
2. 使用 mandrill 发送邮件
mandrill 是一款强大的 smtp 提供器。开发者倾向于使用一个第三方 smtp provider 来获取更好的收件交付。
下面的函数中，你需要把 “mandrill.php” 放在同一个文件夹，作为 php 文件，这样就可以使用ta来发送邮件。
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); } “$apikey = 'xxxxxxxxxx'; //specify your api key here”这里需要你指定你的 api 密钥（从 mandrill 账户中获得）。
语法：
<?php$to = "abc@example.com";$subject = "this is a test email";$message = "hello world!"; send_email($to,$subject,$message);?>
为了达到最好的效果，最好按照 mandrill 的教程去配置 dns。
3. php 函数：阻止 sql 注入
sql 注入或者 sqli 常见的攻击网站的手段，使用下面的代码可以帮助你防止这些注入。
function clean($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 $output;
}
语法：
<?php$text = "<script>alert(1)</script>";$text = clean($text);echo $text;?>
4. 检测用户位置
使用下面的函数，可以检测用户是在哪个城市访问你的网站。
function detect_city($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 $default; } }
语法：
<?php$ip = $_server['remote_addr'];$city = detect_city($ip);echo $city;?>
5. 获取 web 页面的源代码
使用下面的函数，可以获取任意 web 页面的 html 代码。
function display_sourcecode($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($line) . "<br>\n"; } } 语法： <?php$url = "http://blog.koonk.com";$source = display_sourcecode($url);echo $source;?>
6. 计算喜欢你的 facebook 页面的用户
function fb_fan_count($facebook_name) { $data = json_decode(file_get_contents("https://graph.facebook.com/".$facebook_name)); $likes = $data->likes; return $likes; }
语法：
<?php$page = "koonktechnologies";$count = fb_fan_count($page);echo $count;?>
7. 确定任意图片的主导颜色
function dominant_color($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 查询
使用下面的函数可以获取任何域名用户的完整细节。
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 $output; }
语法：
<?php$domain = "http://www.blog.koonk.com";$result = whois_query($domain);print_r($result);?>
9. 验证邮箱地址
有时候，当在网站填写表单，用户可能会输入错误的邮箱地址，这个函数可以验证邮箱地址是否有效。
function is_validemail($email) {$check = 0;if(filter_var($email,filter_validate_email)) {$check = 1; }return $check; }
语法：
<?php$email = "blog@koonk.com";$check = is_validemail($email);echo $check;// if the output is 1, then email is valid.?>
10. 获取用户的真实 ip
function getrealipaddr() { if (!emptyempty($_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 $ip; }
语法：
<?php$ip = getrealipaddr();echo $ip;?>
