Ultra-Practical php code snippets

Every Programmer and developer likes to discuss their favorite code snippets, especially when PHP developers spend several hours coding for webpages or creating applications, they know the importance of these codes. To save coding time, I collected some useful code snippets to help developers improve their work efficiency.

1) Whois query using PHP -- use PHP to retrieve Whois requests

Using this code, you can obtain whois information in a specific domain name. Take the domain name as a parameter and display the relevant information of all domain names.

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</a>    //    $servers = array(        "biz" => "whois.neulevel.biz",        "com" => "whois.internic.net",        "us" => "whois.nic.us",        "coop" => "whois.nic.coop",        "info" => "whois.nic.info",        "name" => "whois.nic.name",        "net" => "whois.internic.net",        "gov" => "whois.nic.gov",        "edu" => "whois.internic.net",        "mil" => "rs.internic.net",        "int" => "whois.iana.org",        "ac" => "whois.nic.ac",        "ae" => "whois.uaenic.ae",        "at" => "whois.ripe.net",        "au" => "whois.aunic.net",        "be" => "whois.dns.be",        "bg" => "whois.ripe.net",        "br" => "whois.registro.br",        "bz" => "whois.belizenic.bz",        "ca" => "whois.cira.ca",        "cc" => "whois.nic.cc",        "ch" => "whois.nic.ch",        "cl" => "whois.nic.cl",        "cn" => "whois.cnnic.net.cn",        "cz" => "whois.nic.cz",        "de" => "whois.nic.de",        "fr" => "whois.nic.fr",        "hu" => "whois.nic.hu",        "ie" => "whois.domainregistry.ie",        "il" => "whois.isoc.org.il",        "in" => "whois.ncst.ernet.in",        "ir" => "whois.nic.ir",        "mc" => "whois.ripe.net",        "to" => "whois.tonic.to",        "tv" => "whois.tv",        "ru" => "whois.ripn.net",        "org" => "whois.pir.org",        "aero" => "whois.information.aero",        "nl" => "whois.domain-registry.nl"    );     if (!isset($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;}

2) Text messaging with PHP using the TextMagic API -- use TextMagic API to get PHP Test information

TextMagic introduces powerful core APIs to easily send SMS messages to mobile phones. This API is billed.

the TextMagic PHP librequire('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 )

3) Get info about your memory usage -- Get memory usage

This code helps you get the memory usage.

echo "Initial: ".memory_get_usage()." bytes \n";/* printsInitial: 361400 bytes*/ // let's use up some memoryfor ($i = 0; $i < 100000; $i++) {    $array []= md5($i);} // let's remove half of the arrayfor ($i = 0; $i < 100000; $i++) {    unset($array[$i]);} echo "Final: ".memory_get_usage()." bytes \n";/* printsFinal: 885912 bytes*/ echo "Peak: ".memory_get_peak_usage()." bytes \n";/* printsPeak: 13687072 bytes*/

4) Display source code of any webpage -- view the source code of any web page

If you want to view the source code of the webpage, you only need to change the URL of the second line and the source code will be displayed on the webpage.

  $line) {    // loop thru each line and prepend line numbers    echo "Line #{$line_num} : " . htmlspecialchars($line) . "\n";}

5) Create data uri's -- Create data uri

By using this code, you can create a data Uri, which is very useful for embedding images in HTML/CSS and can help save HTTP requests.

function data_uri($file, $mime) {  $contents=file_get_contents($file);  $base64=base64_encode($contents);  echo "data:$mime;base64,$base64";}

6) Detect location by IP -- retrieve the geographical location through IP

This code helps you find a specific IP address. you only need to enter an IP address in the function parameter to check the location.

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('{City : ([^<]*)}i’, $content, $regs) ) { $city = $regs[1]; } if ( preg_match(‘{ State/Province : ([^<]*)  }i’, $content, $regs) ) { $state = $regs[1]; } if( $city!=” && $state!=” ){ $location = $city . ‘, ‘ . $state; return $location; }else{ return $default; } }

7) Detect browser language -- view the browser language

Detects the code scripting language used by the browser.

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;}

8) Check if server is HTTPS -- Check whether the server is HTTPS

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

9) Generate CSV file from a PHP array--generate a. CSV file in the PHP Group

function generateCsv($data, $delimiter = ',', $enclosure = '"') {   $handle = fopen('php://temp', 'r+');   foreach ($data as $line) {           fputcsv($handle, $line, $delimiter, $enclosure);   }   rewind($handle);   while (!feof($handle)) {           $contents .= fread($handle, 8192);   }   fclose($handle);   return $contents;}
