1.发送 SMS

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 verification
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

//get response
$output = curl_exec($ch);
//Print error if any
if(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工具。

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",

function makeClickableLinks($text)
{
$text = eregi_replace('(((f|ht){1}tp://)[-a-zA-Z0-9@:%_+.~#?&//=]+)',
'<a href="\1">\1</a>', $text);
$text = eregi_replace('([[:space:]()[{}])(www.[-a-zA-Z0-9@:%_+.~#?&//=]+)',
'\1<a href="http://\2">\2</a>', $text);
$text = eregi_replace('([_.0-9a-z-]+@([0-9a-z][0-9a-z-]+.)+[a-z]{2,3})',
'<a href="mailto:\1">\1</a>', $text);

return $text;
}

语法：

<?php
$text = "This is my first post on http://blog.koonk.com"; $text = makeClickableLinks($text);
echo $text;
?>

12.阻止多个 IP 访问你的网站

这个代码片段可以方便你禁止某些特定的 IP 地址访问你的网站。

if ( !file_exists('blocked_ips.txt') ) {
$deny_ips = array(
'127.0.0.1',
'192.168.1.1',
'83.76.27.9',
'192.168.1.163'
);
} else {
$deny_ips = file('blocked_ips.txt');
}
// read user ip adress:
$ip = isset($_SERVER['REMOTE_ADDR']) ? trim($_SERVER['REMOTE_ADDR']) : '';

// search current IP in $deny_ips array
if ( (array_search($ip, $deny_ips))!== FALSE ) {
// address is blocked:
echo 'Your IP adress ('.$ip.') was blocked!';
exit;
}

header("Content-type: application/force-download");
header('Content-Disposition: inline; filename="' . $dir.$file . '"');
header("Content-Transfer-Encoding: Binary");
header("Content-length: ".filesize($dir.$file));
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="' . $file . '"');

echo json_encode($json_data);

15.压缩 zip 文件

使用下面的 PHP 片段可以即时压缩 zip 文件。

function create_zip($files = array(),$destination = '',$overwrite = false) {
//if the zip file already exists and overwrite is false, return false
if(file_exists($destination) && !$overwrite) { return false; }
//vars
$valid_files = array();
//if files were passed in...
if(is_array($files)) {
//cycle through each file
foreach($files as $file) {
//make sure the file exists
if(file_exists($file)) {
$valid_files[] = $file;
}
}
}
//if we have good files...
if(count($valid_files)) {
//create the archive
$zip = new ZipArchive();
if($zip->open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) {
return false;
}
//add the files
foreach($valid_files as $file) {
$zip->addFile($file,$file);
}
//debug
//echo 'The zip archive contains ',$zip->numFiles,' files with a status of ',$zip->status;

//close the zip -- done!
$zip->close();

//check to make sure the file exists
return file_exists($destination);
}
else
{
return false;
}
}

copy($location.'/'.$file,$newLocation.'/'.$file);
unlink($location.'/'.$file);
}
return TRUE;
}else{
return FALSE;
}
}

语法：

<?php
unzip('test.zip','unziped/test'); //File would be unzipped in unziped/test folder
?>

17.缩放图片

function resize_image($filename, $tmpname, $xmax, $ymax)
{
$ext = explode(".", $filename);
$ext = $ext[count($ext)-1];

if($ext == "jpg" || $ext == "jpeg")
$im = imagecreatefromjpeg($tmpname);
elseif($ext == "png")
$im = imagecreatefrompng($tmpname);
elseif($ext == "gif")
$im = imagecreatefromgif($tmpname);

$x = imagesx($im);
$y = imagesy($im);

if($x <= $xmax && $y <= $ymax)
return $im;

if($x >= $y) {
$newx = $xmax;
$newy = $newx * $y / $x;
}
else {
$newy = $ymax;
$newx = $x / $y * $newy;
}

$im2 = imagecreatetruecolor($newx, $newy);
imagecopyresized($im2, $im, 0, 0, 0, 0, floor($newx), floor($newy), $x, $y);
return $im2;
}

18.使用 mail() 发送邮件

$headers .= "Reply-To: blog@koonk.com\r\n";
$headers .= "Return-Path: blog@koonk.com\r\n";
$headers .= "X-Mailer: PHP5\n";
$headers .= 'MIME-Version: 1.0' . "\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
mail($to,$subject,$body,$headers);
}
