1. 發(fā)送短信調用 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 = $router->send(’Wake up!’, array(9991234567), true); // result: Result is: Array ( [messages] => Array ( [19896128] => 9991234567 ) [sent_text] => Wake up! [parts_count] => 1 ) 2. 根據IP查找地址function detect_city($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. 顯示網頁的源代碼<?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($line) . '<br>n'; } 4. 檢查服務器是否使用HTTPSif ($_SERVER[’HTTPS’] != 'on') { echo 'This is not HTTPS'; }else{ echo 'This is HTTPS'; } 5. 顯示Facebook粉絲數量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 $data->likes; } 6. 檢測圖片的主要顏色$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/$total); 7. 獲取內存使用信息echo 'Initial: '.memory_get_usage().' bytes n'; /* prints Initial: 361400 bytes */ // let’s use up some memory for ($i = 0; $i < 100000; $i++) { $array []= md5($i); } // let’s remove half of the array for ($i = 0; $i < 100000; $i++) { unset($array[$i]); } echo 'Final: '.memory_get_usage().' bytes n'; /* prints Final: 885912 bytes */ echo 'Peak: '.memory_get_peak_usage().' bytes n'; /* prints Peak: 13687072 bytes */ 8. 使用 gzcompress() 壓縮數據$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檢查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, $domain.'rn'); while(!feof($conn)) { $output .= fgets($conn,128); } fclose($conn); } else { die(’Error: Could not connect to ’ . $nic_server . ’!’); } return $output; } 10. 通過Email發(fā)送PHP錯誤<?php // Our custom error handler function nettuts_error_handler($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) .
