非常に便利な 10 個の PHP コードを共有します

1. SMS を送信する

TextMagic API を呼び出します。

// 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. IPに基づいてアドレスを検索します

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. Webページのソースコードを表示します

<?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. サーバーがHTTPを使用しているかどうかを確認します。 S

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

5. Facebook のファンの数を表示します

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. 写真のメインカラーを検出します

$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.

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() を使用してデータを圧縮します

$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);
