澳门新葡亰平台游戏网站又十个超级有用的PHP代码片段

好东西要我们一道享受,上次分享了11个,此番再来10个最棒有用的PHP代码片段。

1. 出殡和下葬短信

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 )

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)'; $url = '_locator.phpip=' . urlencode($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 = '' . $_SERVER['HTTP_HOST'], ); curl_setopt_array($ch, $curl_opt); $content = curl_exec($ch); if (!is_null($curl_info)) { $curl_info = curl_getinfo($ch); } curl_close($ch); if ( preg_match('{liCity : ([^]*)/li}i', $content, $regs) ) { $city = $regs[1]; } if ( preg_match('{liState/Province : ([^]*)/li}i', $content, $regs) ) { $state = $regs[1]; } if( $city!='' && $state!='' ){ $location = $city . ', ' . $state; return $location; }else{ return $default; } } 

3. 呈现网页的源代码

php // display source code $lines = file(”); foreach ($lines as
$line_num = $line) { // loop thru each line and prepend line numbers
echo “Line #b{$line_num}/b : ” . htmlspecialchars($line) . “br/n”; }
4. 反省服务器是不是选拔HTTPS

if ($_SERVER['HTTPS'] != "on") { echo "This is not HTTPS"; }else{ echo "This is HTTPS"; } 

5. 呈现Facebook观众数量

function fb_fan_count($facebook_name){ // Example:  $data = json_decode(file_get_contents("".$facebook_name)); echo $data-likes; } 

6. 检查测试图片的主要性颜色

$i = imagecreatefromjpeg("image.jpg"); for ($x=0;$ximagesx($i);$x++) { for ($y=0;$yimagesy($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. 收获内部存款和储蓄器使用音信

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. 行使 gzcompress(卡塔尔(قطر‎ 压缩数量

$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('/^', '', $domain); $domain = preg_replace('/^', '', $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: // //  // $servers = array( "biz" = "whois.neulevel.biz", "com" = "whois.internic.net", "us" = "whois.nic.us", "coop" = "whois.nic.coop", "info" = "whois.nic.info", "name" = "whois.nic.name", "net" = "whois.internic.net", "gov" = "whois.nic.gov", "edu" = "whois.internic.net", "mil" = "rs.internic.net", "int" = "whois.iana.org", "ac" = "whois.nic.ac", "ae" = "whois.uaenic.ae", "at" = "whois.ripe.net", "au" = "whois.aunic.net", "be" = "whois.dns.be", "bg" = "whois.ripe.net", "br" = "whois.registro.br", "bz" = "whois.belizenic.bz", "ca" = "whois.cira.ca", "cc" = "whois.nic.cc", "ch" = "whois.nic.ch", "cl" = "whois.nic.cl", "cn" = "whois.cnnic.net.cn", "cz" = "whois.nic.cz", "de" = "whois.nic.de", "fr" = "whois.nic.fr", "hu" = "whois.nic.hu", "ie" = "whois.domainregistry.ie", "il" = "whois.isoc.org.il", "in" = "whois.ncst.ernet.in", "ir" = "whois.nic.ir", "mc" = "whois.ripe.net", "to" = "whois.tonic.to", "tv" = "whois.tv", "ru" = "whois.ripn.net", "org" = "whois.pir.org", "aero" = "whois.information.aero", "nl" = "whois.domain-registry.nl" ); if (!isset($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){ $email = " pAn error ($number) occurred on line strong$line/strong and in the strongfile: $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; 

是还是不是也很完美,和前面的一齐珍藏吧
