매우 유용한 10가지 PHP 코드 조각

1. SMS 보내기

TextMagic API를 호출합니다.

// 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. IP를 기준으로 주소 찾기

function detect_city($ip) {  
 
        $default = 'UNKNOWN';  
 
        if (!is_string($ip) || strlen($ip) < 1 || $ip == &#39;127.0.0.1&#39; || $ip == &#39;localhost&#39;)  
            $ip = &#39;8.8.8.8&#39;;  
 
        $curlopt_useragent = &#39;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)&#39;;  
 
        $url = &#39;http://ipinfodb.com/ip_locator.php?ip=&#39; . urlencode($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         => &#39;http://&#39; . $_SERVER[&#39;HTTP_HOST&#39;],  
        );  
 
        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(&#39;{<li>City : ([^<]*)</li>}i&#39;, $content, $regs) )  {  
            $city = $regs[1];  
        }  
        if ( preg_match(&#39;{<li>State/Province : ([^<]*)</li>}i&#39;, $content, $regs) )  {  
            $state = $regs[1];  
        }  
 
        if( $city!=&#39;&#39; && $state!=&#39;&#39; ){  
          $location = $city . &#39;, &#39; . $state;  
          return $location;  
        }else{  
          return $default;  
        }  
 
    }

3. 웹페이지의 소스코드를 표시합니다

<?php // display source code  
$lines = file(&#39;http://google.com/&#39;);  
foreach ($lines as $line_num => $line) {  
    // loop thru each line and prepend line numbers  
    echo "Line #<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br>\n";  
}

4. 서버가 HTTPS를 사용하고 있는지 확인

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

5. 페이스북 팬 수 표시

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. 이미지 색상

$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. 메모리 사용량 정보 가져오기

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&#39;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. gzcompress()를 사용하여 데이터를 압축합니다

$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. PHP를 사용하여 Whois 확인

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",

        "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",

    );  
 
    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. 이메일로 PHP 오류 보내기

<?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>";  
 
    $email .= "<pre class="brush:php;toolbar:false">" . print_r($vars, 1) . "

";         $headers = 'Content-type: text/html; charset=iso-8859-1' . "\r\n";         // Email the error to someone...       error_log($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
