重寫Laravel Socialite

最近需要用到OAuth的Client套件 所以就使用目前最多人使用的Laravel 不過需要的部份只有Laravel Socialite 看了一下composer.json的相依性 ```json "require": { "php": ">=5.4.0", "illuminate/contracts": "~5.0", "illuminate/http": "~5.0", "illuminate/support": "~5.0", "guzzlehttp/guzzle": "~5.0|~6.0", "league/oauth1-client": "~1.0" }, ``` 只需要這些package並不需要整個Laravel 所以就開始使用它 不過在使用的過程遇到了不少問題 它所需要的package其實不止這些 所以程式在撰寫的過程中確實遇到不少問題 再在上在本機端上開發會遇到cURL error 60: SSL certificate problem 於是決定以[PHPoAuthLib](https://github.com/Lusitanian/PHPoAuthLib.git)進行開發 所以就寫了[Recca0120 Socialite](https://github.com/recca0120/Socialite) 並使它可以獨立使用 [Demo](https://github.com/recca0120/Socialite/tree/master/demo) 目前只先實作Laravel Socialite原本的功能，之後會視情形再加功能 OAuth1 BitBucket Twitter OAuth2 Facebook GitHub Google Instagram LinkedIn

cURL error 60: SSL certificate problem: unable to get local issuer certificate

 在使用Guzzle時，遇到cURL error 60: SSL certificate problem: unable to get local issuer certificate 只要下載[ca-bundle.crt](https://raw.githubusercontent.com/bagder/ca-bundle/master/ca-bundle.crt)並放到相對應的路徑 ```php [ // Red Hat, CentOS, Fedora (provided by the ca-certificates package) '/etc/pki/tls/certs/ca-bundle.crt', // Ubuntu, Debian (provided by the ca-certificates package) '/etc/ssl/certs/ca-certificates.crt', // FreeBSD (provided by the ca_root_nss package) '/usr/local/share/certs/ca-root-nss.crt', // OS X provided by homebrew (using the default path) '/usr/local/etc/openssl/cert.pem', // Google app engine '/etc/ca-certificates.crt', // Windows? 'C:\\windows\\system32\\curl-ca-bundle.crt', 'C:\\windows\\curl-ca-bundle.crt', ]; ``` 如果再無法正常運作的話就得去修改php.ini 再加入 ```ini [curl] curl.cainfo=C:\Windows\curl-ca-bundle.crt [openssl] openssl.cafile=C:\Windows\curl-ca-bundle.crt ``` 就可以正常運作了

發撲克牌

在奇摩知識+看到有人發問發撲克牌，依花色及數字大小做排序，所以我就寫了這個程式囉
```php function Poker($member = 4, $POSTCARDS = 52) { /*撲克花色*/ $Poker = [ 'Spades', 'Hearts', 'Diamonds', 'Clubs', ]; /*人頭牌*/ $CARD = [ 11 => 'J', 12 => 'Q', 13 => 'K', ]; /*發牌順序*/ $P = range(0, $POSTCARDS - 1); shuffle($P); /*存放結果陣列*/ $result = []; $total = count($P); for ($i = 0; $i < $total; $i++) { /*發給玩家*/ $t = $i % $member + 1; /*發牌編號 0-51*/ $v = $P[$i]; /*發牌花色 Spades,Hearts,Diamonds,Clubs*/ $c = $Poker[$v % count($Poker)]; /*花色大小 1-13*/ $k = ($v % 13) + 1; $result[$t][$c][$k] = (in_array($k, array_keys($CARD))) ? $CARD[$k] : $k; /*依牌大小排序*/ krsort($result[$t][$c]); /*依花色排序*/ krsort($result[$t]); } return $result; } /*印出結果*/ print_r(Poker(1, 13)); /*如果要發4個人52張牌*/ print_r(Poker(4, 52)); ```

php 下載限速

```php function getlocalfile($filename, $readmod = 1, $range = 0) { if ($fp = @fopen($filename, 'rb')) { @fseek($fp, $range); $download_rate = 10;//限制网速10kb/s while (! feof($fp)) { print fread($fp, round($download_rate * 1024)); flush(); ob_flush(); sleep(1); } } @fclose($fp); @flush(); @ob_flush(); } ```
