1. 发送短信

调用 TextMagicAPI。

// 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) < 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('{<li>City : ([^<]*)</li>}i', $content, $regs) ) {
$city = $regs[1];
}
if ( preg_match('{<li>State/Province : ([^<]*)</li>}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

<?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
