isolated 十个超级有用的PHP代码片段

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) $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;
    }

    }


    3. 显示网页的源代码

    $lines = file('http://google.com/');
    foreach ($lines as $line_num => $line) {
    // loop thru each line and prepend line numbers
    echo "Line #{$line_num} : " . htmlspecialchars($line) . "
    \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Faceboo**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 ($x=0;$xfor ($y=0;$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
    */
    // http://www.baoluowanxiang.com/
    // let's use up some memory
    for ($i = 0; $i $array []= md5($i);
    }

    // let's remove half of the array
    for ($i = 0; $i unset($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


    // Our custom error handler
    function nettuts_error_handler($number, $message, $file, $line, $vars){
    $email = "

    An error ($number) occurred on line
    $line and in the file: $file.

    $message

    ";

    $email .= "
    " . print_r($vars, 1) . "
    Nach dem Login kopieren
    ";

    $headers = 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

    // Email the error to someone...
    error_log($email, 1, [email protected]', $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 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;
