PHP开发中敲代码是最能磨练人意志的，面对枯燥的代码有些人感兴趣，然而有些人不耐烦，面对如此多的代码总想着可以复制粘贴，以提高效率。PHP代码有这种功能，今天小编给大家推荐一些PHP代码神器，十个超极好的用的PHP代码片段信手拈来，直接拿去用吧！

列举十个PHP代码片段，超强神器！

1、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;

}

}

2、查找Longitudes与Latitudes之间的距离

function getDistanceBetweenPointsNew($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;

return compact('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: 2.6025

feet: 13,741.4350

yards: 4,580.4783

kilometers: 4.1884

meters: 4,188.3894

3、清理用户输入

]*?>.*?@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('{

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; } }

5、设置密码强度

100){

$strength = 100;

}

return $strength;

}

var_dump(password_strength("Correct Horse Battery Staple"));

echo "

";

var_dump(password_strength("Super Monkey Ball"));

echo "

";

var_dump(password_strength("Tr0ub4dor&3"));

echo "

";

var_dump(password_strength("abc123"));

echo "

";

var_dump(password_strength("sweet"));

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URL

function 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-cool

function make_seo_name($title) {

return preg_replace('/[^a-z0-9_-]/i', '', strtolower(str_replace(' ', '-', trim($title))));

}

9.1、Tweeter Feed Runner——使用任意twitter名，可在任意页面上加载用户资源。

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){

$tweet = preg_replace("/(http(.+?))( |$)/","$1$3", $tweet);

$tweet = preg_replace("/#(.+?)(\h|\W|$)/", "#$1$2", $tweet);

$tweet = preg_replace("/@(.+?)(\h|\W|$)/", "@$1$2", $tweet);

return $tweet;

}

}

9.2、Tweeter Feed Runner——用于在主题中创建文件，比如：example.php

loadTimeline("phpsnips")->getTweets();

foreach($feed as $time => $message){

echo "

";

}

10、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;

}
