标签:com http style c code t size sp ext string art 每位程序员和开发者都喜欢讨论他们最爱的代码片段,尤其是当PHP开发者花费数个小时为网页编码或创建应用时,他们更知道这些代码的重要性。为了节约编码时间,笔者收集了一些较为实用的代码片段,帮助开发者提高工作效率。>>>
点击查看PHP代码片段(一) 1) Whois query using PHP
——利用PHP获取Whois请求 利用这段代码,在特定的域名里可获得whois信息。把域名名称作为参数,并显示所有域名的相关信息。 function
whois_query($domain) { // fix the domain
name: $domain =
strtolower(trim($domain)); $domain =
preg_replace(‘/^http:\/\//i‘, ‘‘, $domain); $domain =
preg_replace(‘/^www\./i‘, ‘‘, $domain); $domain = explode(‘/‘,
$domain); $domain =
trim($domain[0]); // split the TLD from
domain name $_domain = explode(‘.‘,
$domain); $lst =
count($_domain)-1; $ext =
$_domain[$lst]; // You find resources and
lists // like these on
wikipedia: // // http://de.wikipedia.org/wiki/Whois // $servers =
array( "biz" =>
"whois.neulevel.biz", "com" =>
"whois.internic.net", "us" =>
"whois.nic.us", "coop" =>
"whois.nic.coop", "info" =>
"whois.nic.info", "name" =>
"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.ncst.ernet.in", "ir" =>
"whois.nic.ir", "mc" =>

"whois.ripn.net", "org" =>
"whois.pir.org", "aero" =>
"whois.information.aero", "nl" =>
"whois.domain-registry.nl" ); if
(!isset($servers[$ext])){ die(‘Error: No matching nic
server found!‘); } $nic_server =
$servers[$ext]; $output = ‘‘; // connect to whois
server: if ($conn = fsockopen
($nic_server, 43)) { fputs($conn,
$domain."\r\n"); while(!feof($conn))
{ $output .=
fgets($conn,128); } fclose($conn); } else { die(‘Error: Could
not connect to ‘ . $nic_server . ‘!‘); } 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-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 =
$router->send(‘Wake up!‘, array(9991234567), true); // result: Result is: Array
( [messages] => Array ( [19896128] => 9991234567 ) [sent_text] => Wake
up! [parts_count] => 1 ) 3) Get info about your
memory usage——获取内存使用率 这段代码帮助你获取内存使用率。 echo "Initial:
".memory_get_usage()。" bytes \n"; /* prints Initial: 361400
bytes */ // let‘s use up some
memory for ($i = 0; $i $array []=
md5($i); } // let‘s remove half of the
array for ($i = 0; $i unset($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昆明国防医院。
$line) { // loop thru each line and
prepend line numbers echo "Line #{$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, 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 = ‘"‘) { $handle =
fopen(‘php://temp‘, ‘r+‘); foreach ($data as $line)
{ fputcsv($handle, $line,
$delimiter, $enclosure); } rewind($handle); while (!feof($handle))
{ $contents .= fread($handle,
8192); } fclose($handle); return
$contents; } 直接拿来用,超实用的PHP代码片段(二),搜素材,soscw.com 直接拿来用,超实用的PHP代码片段(二) 标签:com http style c code t size sp ext string art 原文地址:http://www.cnblogs.com/hengyi123/p/3701723.html
