    return $output;

　　2) Text messaging with PHP using the TextMagic API ——使用TextMagic API 获取PHP Test信息

　　TextMagic引入强大的核心API，可轻松将SMS发送到手机。该API是需要付费。

the TextMagic PHP lib

require('textmagic-sms-<span >);
 
// 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 )

　　3) Get info about your memory usage——获取内存使用率

　　这段代码帮助你获取内存使用率。

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
*/

　　4) Display source code of any webpage——查看任意网页源代码

　　如果你想查看网页源代码，那么只需更改第二行的URL，源代码就会在网页上显示出。

<?<span id="2_nwp" style="width: auto; height: auto; float: none;"><a id="2_nwl" href="http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=19&is_app=0&jk=c4615ba7eed770c&k=php&k0=php&kdi0=0&luki=9&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=c77ed7eba15460c&ssp2=1&stid=0&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F4038%2Ehtml&urlid=0" target="_blank" mpid="2" style="text-decoration: none;"><span style="color:#0000ff;font-size:14px;width:auto;height:auto;float:none;">php</span></a></span> // display source code $lines = file('http://google.com/'); foreach ($lines as $line_num => $line) { 

    // loop thru each line and prepend line numbers

    echo "Line #{$line_num} : " . htmlspecialchars($line) . "
\n";
}

　　5) Create data uri’s——创建数据uri

通过使用此代码，你可以创建数据Uri，这对在HTML/CSS中嵌入图片非常有用，可帮助节省HTTP请求。

function data_uri($file, $mime) {

  $contents=file_get_contents($file);

  $base64=base64_encode($contents);

  echo "data:$mime;base64,$base64";
}

　　6) Detect location by IP——通过IP检索出地理位置

　　这段代码帮助你查找特定的IP，只需在功能参数上输入IP，就可检测出位置。

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.<span >(             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; } }

　　7) Detect browser language——查看浏览器语言

　　检测浏览器使用的代码脚本语言。

function get_client_language($availableLanguages, $default='en'){

    if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {

        $langs=explode(',',$_SERVER['HTTP_ACCEPT_LANGUAGE']);
 
        foreach ($langs as $value){

            $choice=substr($value,0,2);

            if(in_array($choice, $availableLanguages)){

                return $choice;

            }

        }

    } 

    return $default;
}

　　8) Check if server is HTTPS——检测服务器是否是HTTPS

if ($_SERVER['HTTPS'] != "on") { 

    echo "This is not HTTPS";

}else{

    echo "This is HTTPS";
}

　　9) Generate CSV file from a PHP array——在PHP数组中生成.csv 文件

function generateCsv($data, $delimiter = ',', $enclosure = '"') {

   $handle = fopen('<span >);

   foreach ($data as $line) {

           fputcsv($handle, $line, $delimiter, $enclosure);

   }

   rewind($handle);

   while (!feof($handle)) {

           $contents .= fread($handle, 8192);

   }

   fclose($handle);

   return $contents;
}
