1.查找Longitudes与Latitudes之间的距离
functiongetDistanceBetweenPointsNew($latitude1, $longitude1, $latitude2, $longitude2) { $theta = $longitude1 - $longitude2; $miles = (sin(deg2rad($latitude1)) * sin(deg2rad($latitude2))) + (cos(deg2rad($latitude1)) * cos(deg2rad($latitude2)) * cos(deg2rad($theta))); $miles = acos($miles); $miles = rad2deg($miles); $miles = $miles * 60 * 1.1515; $feet = $miles * 5280; $yards = $feet / 3; $kilometers = $miles * 1.609344; $meters = $kilometers * 1000; returncompact('miles','feet','yards','kilometers','meters');}$point1 = array('lat'=> 40.770623,'long'=> -73.964367);$point2 = array('lat'=> 40.758224,'long'=> -73.917404);$distance = getDistanceBetweenPointsNew($point1['lat'], $point1['long'], $point2['lat'], $point2['long']);foreach ($distance as $unit => $value) { echo $unit.': '.number_format($value,4).'';}The example returns the following:miles: 2.6025feet: 13,741.4350yards: 4,580.4783kilometers: 4.1884meters: 4,188.38942.完善cURL功能
function xcurl($url,$ref=null,$post=array(),$ua="Mozilla/5.0 (X11; Linux x86_64; rv:2.2a1pre) Gecko/20110324 Firefox/4.2a1pre",$print=false) { $ch = curl_init(); curl_setopt($ch, CURLOPT_AUTOREFERER, true); if(!empty($ref)) { curl_setopt($ch, CURLOPT_REFERER, $ref); } curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); if(!empty($ua)) { curl_setopt($ch, CURLOPT_USERAGENT, $ua); } if(count($post) > 0){ curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $post); } $output = curl_exec($ch); curl_close($ch); if($print) { print($output); } else { return $output; }}]*?>.*?@si', // Strip out javascript '@<[\/\!]*?[^<>]*?>@si', // Strip out HTML tags '@]*?>.*?@siU', // Strip style tags properly '@@' // Strip multi-line comments ); $output = preg_replace($search, '', $input); return $output; }?>$val) { $output[$var] = sanitize($val); } } else { if (get_magic_quotes_gpc()) { $input = stripslashes($input); } $input = cleanInput($input); $output = mysql_real_escape_string($input); } return $output;}?>4.通过IP（城市、国家）检测地理位置function detect_city($ip) {
$default = ‘Hollywood, CA';
if (!is_string($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;
}
}
5.设置密码强度
<?php
/**
*
* @param String $string
* @return float
*
* Returns a float between 0 and 100. The closer the number is to 100 the
* the stronger password is; further from 100 the weaker the password is.
*/
function password_strength($string){
$h = 0;
$size = strlen($string);
foreach(count_chars($string, 1) as $v){
$p = $v / $size;
$h -= $p * log($p) / log(2);
}
$strength = ($h / 4) * 100;
if($strength > 100){
$strength = 100;
}
return $strength;
}var_dump(password_strength(“Correct Horse Battery Staple”));6.检测浏览器语言，只提供可用的$availableLanguages作为数组(‘en’, ‘de’, ‘es’)function get_client_language($availableLanguages, $default='en'){ if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) { $langs=explode(',',$_SERVER['HTTP_ACCEPT_LANGUAGE']); //start going through each one foreach ($langs as $value){ $choice=substr($value,0,2); if(in_array($choice, $availableLanguages)){ return $choice; } } } return $default;}7.创建数据URLfunction data_uri($file, $mime) { $contents=file_get_contents($file); $base64=base64_encode($contents); echo "data:$mime;base64,$base64";}8.创建更加友好的页面标题SEO URL输入示例：$title = “This foo’s bar is rockin’ cool!”; echo makeseoname($title); //RETURNS: //this-foos-bar-is-rockin-coolfunction make_seo_name($title) { return preg_replace('/[^a-z0-9_-]/i', '', strtolower(str_replace(' ', '-', trim($title))));}9.终极加密功能// f(ucking) u(ncrackable) e(ncryption) function by BlackHatDBL (www.netforme.net)function fue($hash,$times) { // Execute the encryption(s) as many times as the user wants for($i=$times;$i>0;$i--) { // Encode with base64... $hash=base64_encode($hash); // and md5... $hash=md5($hash); // sha1... $hash=sha1($hash); // sha256... (one more) $hash=hash("sha256", $hash); // sha512 $hash=hash("sha512", $hash); } // Finaly, when done, return the value return $hash;}10a.Tweeter Feed Runner——使用任意twitter名，可在任意页面上加载用户资源。 <?php
class Twitter{
protected $twitURL = 'http://api.twitter.com/1/';
protected $xml;
protected $tweets = array(), $twitterArr = array();
protected $pversion = "1.0.0";
public function pversion(){
return $this->pversion;
}
public function loadTimeline($user, $max = 20){
$this->twitURL .= 'statuses/user_timeline.xml?screen_name='.$user.'&count='.$max;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $this->twitURL);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$this->xml = curl_exec($ch);
return $this;
}
public function getTweets(){
$this->twitterArr = $this->getTimelineArray();
$tweets = array();
foreach($this->twitterArr->status as $status){
$tweets[$status->created_at->__toString()] = $status->text->__toString();
}
return $tweets;
}
public function getTimelineArray(){
return simplexml_load_string($this->xml);
}
public function formatTweet($tweet){
$tweet = preg_replace("/(http(.+?))( |$)/","<a href=\"$0\">$1</a>$3", $tweet);
$tweet = preg_replace("/#(.+?)(\h|\W|$)/", "<a href=\"https://twitter.com/i/#!/search/?q=%23$1&src=hash\">#$1</a>$2", $tweet);
$tweet = preg_replace("/@(.+?)(\h|\W|$)/", "<a href=\"http://twitter.com/#!/$1\">@$1</a>$2", $tweet);
return $tweet;
}
} 10b. Tweeter Feed Runner——用于在主题中创建文件，比如：example.phploadTimeline("phpsnips")->getTweets(); foreach($feed as $time => $message){ echo "<div class='tweet'>".$twitter->formatTweet($message)."<br />At: ".$time."</div>"; }
