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 // $servers = array( "biz" => "whois.neulevel.biz", "com" => "whois.internic.net", "us" => "whois.nic.us", "coop" => "whois.nic.coop", "info" => "whois.nic.info", "name" => "whois.nic.name", "net" => "whois.internic.net", "gov" => "whois.nic.gov", "edu" => "whois.internic.net", "mil" => "rs.internic.net", "int" => "whois.iana.org", "ac" => "whois.nic.ac", "ae" => "whois.uaenic.ae", "at" => "whois.ripe.net", "au" => "whois.aunic.net", "be" => "whois.dns.be", "bg" => "whois.ripe.net", "br" => "whois.registro.br", "bz" => "whois.belizenic.bz", "ca" => "whois.cira.ca", "cc" => "whois.nic.cc", "ch" => "whois.nic.ch", "cl" => "whois.nic.cl", "cn" => "whois.cnnic.net.cn", "cz" => "whois.nic.cz", "de" => "whois.nic.de", "fr" => "whois.nic.fr", "hu" => "whois.nic.hu", "ie" => "whois.domainregistry.ie", "il" => "whois.isoc.org.il", "in" => "whois.ncst.ernet.in", "ir" => "whois.nic.ir", "mc" => "whois.ripe.net", "to" => "whois.tonic.to", "tv" => "whois.tv", "ru" => "whois.ripn.net", "org" => "whois.pir.org", "aero" => "whois.information.aero", "nl" => "whois.domain-registry.nl" ); if (!isset($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:
<"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 = eregi_replace('([[:space:]()[{}])(www.[-a-zA-Z0-9@:%_+.~#"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:
<"This is my first post on http://blog.koonk.com"; $text = makeClickableLinks($text); echo $text; "htmlcode">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']) "htmlcode">function force_download($file) { $dir = "../log/exports/"; if ((isset($file))&&(file_exists($dir.$file))) { header("Content-type: application/force-download"); header('Content-Disposition: inline; filename="' . $dir.$file .

<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。

三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。
首次推出的GDDR7内存模块密度为16GB,每个模块容量为2GB。其速度预设为32 Gbps(PAM3),但也可以降至28 Gbps,以提高产量和初始阶段的整体性能和成本效益。
据三星表示,GDDR7内存的能效将提高20%,同时工作电压仅为1.1V,低于标准的1.2V。通过采用更新的封装材料和优化的电路设计,使得在高速运行时的发热量降低,GDDR7的热阻比GDDR6降低了70%。
