十個超有用的php程式碼片段

[PHP]代碼

1. 傳送簡訊
呼叫 TextMagic API。
// 包含TextMagic PHP 函式庫
require('textmagic-sms-api-php/TextMagicAPI.php');
// 設定使用者名稱和密碼資訊
$username = 'myusername';
$password = 'mypassword';
// 建立一個新的TM 實例
$router = new TextMagicAPI(array(
'username' => ; $ username,
'password' => $password
));
//發送簡訊到'999-123-4567'
$result = $router- >send('醒醒醒吧！來！依照IP找尋位址
function detector_city($ip) {
$default = 'UNKNOWN';
if (!is_string($ip) || strlen($ip ) ) $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_USERAGENT => $curlopt_useragent,
CURLOPT_URL => $url,
CURLOPT_TIMEOUT => 'http://' . 'HTTP_HOST'],
); $ch, $curl_opt);
$content = curl_exec($ch);
if (!is_null ($curl_info)) {
$curl_info = curl_getinfo($ch);
}
curl_close($ch);
if ( preg_match('{
;城市: ([^}i', $ content, $regs) ) {
$city = $regs[1];
}
if ( preg_match( '{
州/省: ([^ }i', $content, $regs) ) {
$state = $regs[1];
}
if( $city!='' && $state!='' ) {
$location = $city . '，'。 $state;
回傳$位置;
}其他{
回傳$default;
}
}
3. 顯示網頁的原始碼
$lines = file('http://google.com/');
foreach ($lines as $line_num => $line) {
//循環遍歷每一行並新增行號
echo "Line #{$line_num} : " . htmlspecialchars($line) 。 “
n”;
}
4. 檢查伺服器是否使用HTTPS
if ($_SERVER['HTTPS'] != "on") {
echo "This is not HTTPS";
}else{
echo "This是HTTPS";
}
5. 顯示Faceboo**絲數
function fb_count( $facebook_name){
// 範例: https://graph.facebook.com/digimantra
$data = json_decode(file_get_contents("https: //graph.facebook.com/".$facebook_name));
echo $data->likes;
}
6. 偵測圖片的主要顏色
$i = imagecreatefromjpeg("image.jpg");
for ($x=0;$xfor ($y=0;$y$rgb = imagecolorat($i,$x,$y);
$r = ($rgb > ;> 16) & 0xFF;
$g = ($rgb >> & 0xFF;
$b = $ rgb & 0xFF;
$rTotal = $r;
$gTotal = $g;
$bTotal = $b;
$total ;
}
}
}
$total ;
}
}
}
}
$rAverage = round($rTotal/$total);
$gAverage = round($gTotal/$total);
$bAverage = round($bTotal/$total);
7. 取得記憶體資訊使用
echo"Initial: " .memory_get_usage()." bytes n";
/* prints
Initial: 361400 bytes
// http://www.baoluowanfang.com/
// 讓我們用增加一些記憶體
for ($i = 0; $i $array []= md5($i);
}
// 讓我們刪除陣列的一半
for ($i = 0; $i unset($array [$i]);
}
echo"Final: ".memory_get_usage()." bytes n";
/* prints
Final: 885912 bytes
*/
/* 列印
峰值：13687072 位元組
*/
8. 使用gzcompress() 來壓縮資料。 🎜> 明智的，醫生沒有價格，
之前沒有 ultricies elit。
sit adipiscing elit 但是對不起，對不起，對不起，恐怕Lacinia eu nola 飲料
id Euismod urna 成員";
$compressed = gzcompress($string);
echo "原始大小："。strlen($string)."n";
/* 列印
原始大小: 800
*/
echo "壓縮後的大小: ". strlen( $compressed)."n";
/* 列印
壓縮大小: 418
*/
//取回
$original = gzuncompress($compressed) ;
9. 使用PHP 做Whois手機
function whois_query($domain) {
//修復網域：
$domain = strtolower(trim($domain));
$域= preg_replace('/^http:///i', '', $domain);
$domain = preg_replace('/^www./i', '', $domain);
$ domain =explode('/', $domain);
$domain = trim($domain[0]);
//從網域分割TLD
$_domain =explode(' .', $domain);
$lst = count($_domain)-1;
$ext = $_domain[$lst];
// 您尋找資源和清單
// 就像維基百科上的這些：
//
// http://de.wikipedia.org/wiki/Whois
//
$servers = array(
"biz" = > "whois.neulevel.biz",
"whois.internic.net",
"whois.nic.us",
"coop" =>"whois.nic .coop",
"whois.nic.info",
"whois.nic.name",
"net " => "whois.internic.net",
"gov" => "whois. nic.gov",
"edu" => "whois.internic.net",
" mil" => "rs.internic.net",
"int" => "whois .iana.org",
"ac" => "whois.nic.ac",
"ae" => "whois.uaenic.ae",
"at" => " whois.ripe .net",
"au" =>; "whois.aunic.net",
"be" =>; "whois.dns.be",
"bg" =>; "whois. ripe.net",
"br" =>; "whois.registro.br",
"bz" =>; "whois.belizenic.bz",
"ca" =>; "whois .cira.ca",
"cc" =>; "whois.nic.cc",
"ch" =>; "whois.nic.ch",
"cl" =>; " whois.nic.cl",
"cn" =>; "whois.cnnic.net.cn",
"cz" =>; "whois.nic.cz",
"de" = >; "whois.nic.de",
"fr" =>; "whois.nic.fr",
"hu" =>; "whois.nic.hu",
"ie" =>; "whois.domainregistry.ie",
"il" =>; "whois.isoc.org.il",
"在"=>; "whois.ncst.ernet.in",
"ir" =>; "whois.nic.ir",
"mc" =>; "whois.ripe.net",
"至" => "whois.tonic.to",
"tv" =>; "whois.tv",
"ru" =>; "whois.ripn.net",
"org" =>; "whois.pir.org",
"aero" =>; "whois.information.aero",
"nl" =>; "whois.domain-registry.nl"
);
if (!isset($ servers[$ext])){
die('錯誤：找不到符合的網卡伺服器！ ') ;
}
$nic_server = $servers[$ext];
$output = '';
// 連接到whois 伺服器:
if ($conn = fsockopen ($nic_server, 43)) {
fputs($conn, $domain."rn");
while(!feof($conn)) {
$output . = fgets ($conn,128);
}
fclose($conn);
}
else { die('錯誤: 無法連線到' . $nic_server . '!'); }
回傳$output;
}
10。透過Email傳送PHP錯誤
//我們自訂的錯誤處理程序
function nettuts_error_handler($number, $message, $file, $line, $vars) {
$email = "
$line 行和檔案$file 中發生錯誤（$number）。強>
$訊息";

$email .= "
" 。 print_r($vars, 1) 。 "
登入後複製
";

$headers = '內容類型：text/html;字元集=iso-8859-1' 。 "rn";

// 透過電子郵件將錯誤發送給某人...

error_log($email, 1, 'you@youremail.com', $headers);

//確保您決定如何回應錯誤（在使用者方面）

// 要麼回顯錯誤訊息，要麼終止整個專案。由你決定...

// 下面的程式碼確保我們只在錯誤超過

// 只是一個通知時「死亡」。

if ( ($number !== E_NOTICE) && ($number die("出現錯誤，請稍後再試。");

}

}

// 我們應該使用我們的自訂函數來處理錯誤。

set_error_handler('nettuts_error_handler');

// 觸發錯誤...（var 不存在）

echo$somevarthatdoesnotexist;
