好东西要大家一起分享，上次分享了十个，这次再来十个超级有用的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

3. 显示网页的源代码

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

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;$x<imagesx($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. 获取内存使用信息

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. 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

10. 通过Email发送PHP错误
