1. 发送短信
调用 TextMagic API。
-
// Include the TextMagic PHP lib
- require('textmagic-sms-api-php/TextMagicAPI.php');
- // Set the username and password information
- $username = 'myusername';
- $password = 'mypassword';
- // Create a new instance of TM
- $router = new TextMagicAPI(array(
- 'username' => $username,
- 'password' => $password
- ));
- // Send a text message to '999-123-4567'
- $result = $router->send('Wake up!', array(9991234567), true);
- // result: Result is: Array ( [messages] => Array ( [19896128] => 9991234567 ) [sent_text] => Wake up! [parts_count] => 1 )
2. 根据IP查找地址
-
function detect_city($ip) {
- $default = 'UNKNOWN';
- if (!is_string($ip) || strlen($ip) < 1 || $ip == '127.0.0.1' || $ip == 'localhost')
- $ip = '8.8.8.8';
- $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;
- }
- }
3. 显示网页的源代码
-
<?php // display source code
- $lines = file('http://google.com/');
- foreach ($lines as $line_num => $line) {
- // loop thru each line and prepend line numbers
- echo "Line #<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br>\n";
- }
4. 检查服务器是否使用HTTPS
-
if ($_SERVER['HTTPS'] != "on") {
- echo "This is not HTTPS";
- }else{
- echo "This is HTTPS";
- }
5. 显示Facebook粉丝数量
-
function fb_fan_count($facebook_name){
- // Example: https://graph.facebook.com/digimantra
- $data = json_decode(file_get_contents("https://graph.facebook.com/".$facebook_name));
- echo $data->likes;
- }
6. 检测图片的主要颜色
-
$i = imagecreatefromjpeg("image.jpg");
- for ($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/$total);
7. 获取内存使用信息
-
echo "Initial: ".memory_get_usage()." bytes \n";
- /* prints
- Initial: 361400 bytes
- */
- // let's use up some memory
- for ($i = 0; $i < 100000; $i++) {
- $array []= md5($i);
- }
- // let's remove half of the array
- for ($i = 0; $i < 100000; $i++) {
- unset($array[$i]);
- }
- echo "Final: ".memory_get_usage()." bytes \n";
- /* prints
- Final: 885912 bytes
- */
- echo "Peak: ".memory_get_peak_usage()." bytes \n";
- /* prints
- Peak: 13687072 bytes
- */
8. 使用 gzcompress() 压缩数据
-
$string =
- "Lorem ipsum dolor sit amet, consectetur
- adipiscing elit. Nunc ut elit id mi ultricies
- adipiscing. Nulla facilisi. Praesent pulvinar,
- sapien vel feugiat vestibulum, nulla dui pretium orci,
- non ultricies elit lacus quis ante. Lorem ipsum dolor
- sit amet, consectetur adipiscing elit. Aliquam
- pretium ullamcorper urna quis iaculis. Etiam ac massa
- sed turpis tempor luctus. Curabitur sed nibh eu elit
- mollis congue. Praesent ipsum diam, consectetur vitae
- ornare a, aliquam a nunc. In id magna pellentesque
- tellus posuere adipiscing. Sed non mi metus, at lacinia
- augue. Sed magna nisi, ornare in mollis in, mollis
- sed nunc. Etiam at justo in leo congue mollis.
- Nullam in neque eget metus hendrerit scelerisque
- eu non enim. Ut malesuada lacus eu nulla bibendum
- id euismod urna sodales. ";
- $compressed = gzcompress($string);
- echo "Original size: ". strlen($string)."\n";
- /* prints
- Original size: 800
- */
- echo "Compressed size: ". strlen($compressed)."\n";
- /* prints
- Compressed size: 418
- */
- // getting it back
- $original = gzuncompress($compressed);
9. 使用PHP做Whois检查
-
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 $output;
- }
10. 通过Email发送PHP错误
-
<?php
- // Our custom error handler
- function nettuts_error_handler($number, $message, $file, $line, $vars){
- $email = "
- <p>An error ($number) occurred on line
- <strong>$line</strong> and in the <strong>file: $file.</strong>
- <p> $message </p>";
- $email .= "<pre>" . print_r($vars, 1) . "</pre>";
- $headers = 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
- // Email the error to someone...
- error_log($email, 1, 'you@youremail.com', $headers);
- // Make sure that you decide how to respond to errors (on the user's side)
- // Either echo an error message, or kill the entire project. Up to you...
- // The code below ensures that we only "die" if the error was more than
- // just a NOTICE.
- if ( ($number !== E_NOTICE) && ($number < 2048) ) {
- die("There was an error. Please try again later.");
- }
- }
- // We should use our custom function to handle errors.
- set_error_handler('nettuts_error_handler');
- // Trigger an error... (var doesn't exist)
- echo $somevarthatdoesnotexist;
