在编写代码的时候有个神奇的工具总是好的!下面这里收集了 40+ PHP 代码片段,可以帮助你开发 PHP 项目。
这些 PHP 片段对于 PHP 初学者也非常有帮助,非常容易学习,让我们开始学习吧~
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:

<"Hello World";
$mobile = "918112998787";
send_sms($mobile,$message);
"htmlcode">
function send_email($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:

<"abc@example.com";
$subject = "This is a test email";
$message = "Hello World!";
send_email($to,$subject,$message);
"htmlcode">
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:

<"<script>alert(1)</script>";
$text = clean($text);
echo $text;
"htmlcode">
function detect_city($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)';
          
    $url = 'http://ipinfodb.com/ip_locator.php"htmlcode">
<"htmlcode">
function display_sourcecode($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) . "\n";
}
}

语法:

<"http://blog.koonk.com";
$source = display_sourcecode($url);
echo $source;
"htmlcode">
function fb_fan_count($facebook_name)
{
  $data = json_decode(file_get_contents("https://graph.facebook.com/".$facebook_name));
  $likes = $data->likes;
  return $likes;
}

语法:

<"koonktechnologies";
$count = fb_fan_count($page);
echo $count;
"htmlcode">
function dominant_color($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",

    "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:

<"http://www.blog.koonk.com";
$result = whois_query($domain);
print_r($result);
"htmlcode">
function is_validemail($email)
{
$check = 0;
if(filter_var($email,FILTER_VALIDATE_EMAIL))
{
$check = 1;
}
return $check;
}
    

语法:

<"blog@koonk.com";
$check = is_validemail($email);
echo $check;
// If the output is 1, then email is valid.
"htmlcode">
function getRealIpAddr() 
{ 
  if (!emptyempty($_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:

<"htmlcode">
function makeClickableLinks($text)
{ 
 $text = eregi_replace('(((f|ht){1}tp://)[-a-zA-Z0-9@:%_+.~#"\1">\1</a>', $text);

$text = makeClickableLinks($text);
echo $text;
"htmlcode">
if ( !file_exists('blocked_ips.txt') ) {
 $deny_ips = array(
 '127.0.0.1',
 '192.168.1.1',

    header('Content-Disposition: attachment; filename="' . $file . '"');
    readfile("$dir$file");
  } else {

语法:

<php
force_download("image.jpg");
"htmlcode">
$json_data = array ('id'=>1,'name'=>"Mohit");
echo json_encode($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 "htmlcode">
<"htmlcode">
function unzip($location,$newLocation)
{
    if(exec("unzip $location",$arr)){
      mkdir($newLocation);
      for($i = 1;$i< count($arr);$i++){
        $file = trim(preg_replace("~inflating: ~","",$arr[$i]));
        copy($location.'/'.$file,$newLocation.'/'.$file);
        unlink($location.'/'.$file);
      }
      return TRUE;
    }else{
      return FALSE;
    }
}



语法:

<"htmlcode">
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
 之前我们提供了如何使用 Mandrill 发送邮件的 PHP 代码片段,但是如果你不想使用第三方服务,那么可以使用下面的 PHP 代码片段。

function send_mail($to,$subject,$body)
{
$headers = "From: KOONK\r\n";
$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);
}
   

语法:

<"admin@koonk.com";
$subject = "This is a test mail";
$body = "Hello World!";
send_mail($to,$subject,$body);
"htmlcode">
function secsToStr($secs) {
  if($secs>=86400){$days=floor($secs/86400);$secs=$secs%86400;$r=$days.' day';if($days<>1){$r.='s';}if($secs>0){$r.=', ';}}
  if($secs>=3600){$hours=floor($secs/3600);$secs=$secs%3600;$r.=$hours.' hour';if($hours<>1){$r.='s';}if($secs>0){$r.=', ';}}
  if($secs>=60){$minutes=floor($secs/60);$secs=$secs%60;$r.=$minutes.' minute';if($minutes<>1){$r.='s';}if($secs>0){$r.=', ';}}
  $r.=$secs.' second';if($secs<>1){$r.='s';}
  return $r;
}

语法:

<"56789";
$output = secsToStr($seconds);
echo $output;
"htmlcode">
<"htmlcode">
function list_files($dir)
{
  if(is_dir($dir))
  {
    if($handle = opendir($dir))
    {
      while(($file = readdir($handle)) !== false)
      {
        if($file != "." && $file != ".." && $file != "Thumbs.db"/*pesky windows, images..*/)
        {
          echo '<a target="_blank" href="'.$dir.$file.'">'.$file.'</a>'."\n";
        }
      }
      closedir($handle);
    }
  }
}

语法:

<"images/"); //This will list all files of images folder
"htmlcode">
function get_client_language($availableLanguages, $default='en'){
  if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {
    $langs=explode(',',$_SERVER['HTTP_ACCEPT_LANGUAGE']);
    foreach ($langs as $value){
      $choice=substr($value,0,2);
      if(in_array($choice, $availableLanguages)){
        return $choice;
      }
    }
  }
  return $default;
}

23. 查看 CSV 文件

function readCSV($csvFile){
  $file_handle = fopen($csvFile, 'r');
  while (!feof($file_handle) ) {
    $line_of_text[] = fgetcsv($file_handle, 1024);
  }
  fclose($file_handle);
  return $line_of_text;
}
  

语法:

<"test.csv";
$csv = readCSV($csvFile);
$a = csv[0][0]; // This will get value of Column 1 & Row 1
?>

以上就是本文的全部内容,希望对大家的学习有所帮助。

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
