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 "<div class='tweet'>".$twitter->formatTweet($message)."<br />At: ".$time."</div>";

}

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;

}
