項目開發中經常用到的業務邏輯代碼，總結在此處，備用。

1、加密解密函數：function?encryptDecrypt($key,?$string,?$decrypt){????if($decrypt){????????$decrypted?=?rtrim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256,?md5($key),?base64_decode($string),?MCRYPT_MODE_CBC,?md5(md5($key))),?'12');????????return?$decrypted;????}else{????????$encrypted?=?base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256,?md5($key),?$string,?MCRYPT_MODE_CBC,?md5(md5($key))));????????return?$encrypted;????}}

在使用的時候我們可以為加密的字符串，設置一個加密KEY值，解密的時候傳入這個KEY值即可獲得密文原文。$decrypt取值0和1時分別對應加密、解密。

2、上傳圖片方向糾正：

由于每個人拍照姿勢都不一樣，難免有人拍照上傳的圖片出現倒立的情況，下面這個業務邏輯可以自動糾正上傳圖片的方向。

$image?=?imagecreatefromstring(file_get_contents($_FILES['image_upload']['tmp_name']));$exif?=?exif_read_data($_FILES['image_upload']['tmp_name']);if(!emptyempty($exif['Orientation']))?{????switch($exif['Orientation'])?{????????case?8:????????????$image?=?imagerotate($image,90,0);????????????break;????????case?3:????????????$image?=?imagerotate($image,180,0);????????????break;????????case?6:????????????$image?=?imagerotate($image,-90,0);????????????break;????}}3、拆分姓名中的姓氏和名字/**?*?拆分姓名（姓氏和名字）?*?@param?string?$fullname?全名（如：百里屠蘇）?*?@return?array?一維數組[0=>'姓氏',1=>'名稱']?*?@return?array?*/function?splitName($fullname){????$hyphenated?=?array(????????'百里','北堂','北野','北宮','辟閭',????????'淳于','成公','陳生','褚師','城池',????????'端木','東方','東郭','東野','東門','第五','大狐','段干','段陽','第二','東宮',????????'公孫','公冶','公羊','公良','公西','公孟','公伯','公析','公肩','公堅','公乘','公皙','公戶','公廣','公儀','公祖','公玉','公仲','公上','公門','公山','高堂','高陽','郭公','谷梁','毌將','毌丘','單于','叱干','叱利','車非',????????'獨孤','大野','獨吉','達奚','東里',????????'哥舒','貫丘',????????'皇甫','黃龍','胡母','何陽','赫連','呼延','賀蘭','賀若','黑齒','斛律','斛粟',????????'夾谷','九方','即墨','吉胡',????????'可頻',????????'梁丘','閭丘','洛陽','陵尹','冷富','龍丘','令狐',????????'慕容','萬俟','抹捻',????????'納蘭','南榮',????????'南宮','南郭','女媧','南伯','南容','南門','南野',????????'歐陽','歐侯',????????'濮陽','普周','仆固','仆散','蒲察',????????'青陽','漆雕','亓官','渠丘','屈突','屈盧','鉗耳',????????'壤駟','汝嫣',????????'上官','少室','少叔','司徒','司馬','司空','司寇','士孫','申屠','申徒','申鮮','申叔','夙沙','叔先','叔仲','叔孫','侍其','是云','索盧','厙狄',????????'澹臺','太史','太叔','太公','屠岸','唐古','拓跋','同蹄','禿發',????????'聞人','巫馬','微生','王孫','無庸','完顏',????????'夏侯','西門','信平','鮮于','軒轅','相里','新垣','徐離姓',????????'羊舌','羊角','延陵','於陵','伊祁','吾丘','樂正','宇文','尉遲','耶律',????????'諸葛','顓孫','仲孫','仲長','鐘離','宗政','主父','中叔','左人','左丘','宰父','長兒','仉督','長孫','子車','子書','子桑'????);????$vLength?=?mb_strlen($fullname,?'utf-8');????$lastname?=?'';????$firstname?=?'';//前為姓,后為名????if($vLength?>?2){????????$preTwoWords?=?mb_substr($fullname,?0,?2,?'utf-8');//取命名的前兩個字,看是否在復姓庫中????????if(in_array($preTwoWords,?$hyphenated)){????????????$lastname?=?$preTwoWords;????????????$firstname?=?mb_substr($fullname,?2,?10,?'utf-8');????????}else{????????????$lastname?=?mb_substr($fullname,?0,?1,?'utf-8');????????????$firstname?=?mb_substr($fullname,?1,?10,?'utf-8');????????}????}else?if($vLength?==?2){//全名只有兩個字時,以前一個為姓,后一下為名????????$lastname?=?mb_substr($fullname?,0,?1,?'utf-8');????????$firstname?=?mb_substr($fullname,?1,?10,?'utf-8');????}else{????????$lastname?=?$fullname;????}????return?array($lastname,?$firstname);}4、打印輸出數據到文件/**?*?打印輸出數據到文件?*?@param?mixed?$data?*?@param?bool?$replace?*?@param?string|null?$pathname?*/function?p($data,?$replace?=?false,?$pathname?=?null){????is_null($pathname)?&&?$pathname?=?RUNTIME_PATH?.?date('Ymd')?.?'.txt';????$str?=?(is_string($data)???$data?:?(is_array($data)?||?is_object($data))???print_r($data,?true)?:?var_export($data,?true))?.?'\n';????$replace???file_put_contents($pathname,?$str)?:?file_put_contents($pathname,?$str,?FILE_APPEND);}

這個函數雖然很小巧，但是在調試一些內部執行數據的時候非常有用，且很方便的輸出我們要查看的數據。

5、隨機字符生成/*?*?隨機字符生成?*/function?randStr($len=6,$format='all')?{????switch($format)?{????????case?'all':????????????$chars='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-@#~';?break;????????case?'char':????????????$chars='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz-@#~';?break;????????case?'number':????????????$chars='0123456789';?break;????????case?'charnum':????????????$chars='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';????????????break;????????case?'verify':????????????$chars='ABCDEFGHIJKMNPQRSTUVWXYZ23456789';????????????break;????}????mt_srand();????$password='';????while(strlen($password)<$len)????????$password.=substr($chars,(mt_rand()%strlen($chars)),1);????return?$password;}6、生成唯一訂單號/*?*?生成唯一訂單號?*/function?CreateOrderId(){????$order_id_main?=?date('YmdHis')?.?rand(10000000,99999999);????//訂單號碼主體長度????$order_id_len?=?strlen($order_id_main);????$order_id_sum?=?0;????for($i=0;?$i<$order_id_len;?$i++){????????$order_id_sum?+=?(int)(substr($order_id_main,$i,1));????}????//唯一訂單號碼（YYYYMMDDHHIISSNNNNNNNNCC）????$order_id?=?$order_id_main?.?str_pad((100?-?$order_id_sum?%?100)?%?100,2,'0',STR_PAD_LEFT);????return?$order_id;}7、獲取毫秒級時間戳。

關于獲取毫秒級時間戳其實只需要一行代碼，網上很多人專門寫了很多函數去處理。因為毫秒級的時間戳是13位，int類會溢出。操作使用時可以以float類型或string類型均可。

$timestamp = substr(microtime(true)*1000,0,13);8、獲取文章中的圖片/*?*?獲取文章圖片?*/function?getContentPic($content,$num='1'){????$pattern='/<img.*?src=[\'|\'](.*?)[\'|\'].*?[\/]?>/';????preg_match_all($pattern,htmlspecialchars_decode($content),$match);????if(!emptyempty($match[1])?&&?$num?==?1){????????return?$match[1][0];????}else{????????return?$match[1];????}????return?'';}9、重寫PHP array_push實現自由添加數組鍵值/*?*?重寫array_push?*?@param?$array?array?目標數組?*?@param?$value?mix?鍵值?*?@param?$position?int?索引位置?*?@param?$key?string?鍵名?*?@return?Array?*/function?array_push_position(&$array,?$value=0,?$position,?$key?=?null){????$count?=?0;????$return?=?array();????foreach?($array?as?$k?=>?$v)????{????????if?($count?==?$position)????????{????????????if?(!$key)?$key?=?$count;????????????$return[$key]?=?$value;????????????$inserted?=?true;????????}????????$return[$k]?=?$v;????????$count++;????}????if?(!$key)?$key?=?$count;????if?(!$inserted)?$return[$key];????$array?=?$return;????return?$array;}10、修改XML文件節點

（可以很方便的生成網站地圖，方便SEO優化）

/*?*?Xml文件增加節點?*?@param?$filename?string?文件路徑?*?@param?$data?array?追加數組?*?@param?$nodename?string?節點名稱?*?@return?boole?*/function?addXmlNode($filename,$data,$nodename){????if(is_array($data)?&&?!emptyempty($data)?&&?is_file($filename)?&&?is_string($nodename)){????????$contents?=?file_get_contents($filename);????????$xml?=?@simplexml_load_string($contents);????????foreach($data?as?$key=>$value){????????????foreach($data[$key]?as?$k=>$v){????????????????$item?=?$xml->addChild($nodename);????????????????$item->addChild($k,$v);????????????}????????}????????$xml->asXML();????????$xmlDocument?=?new?DOMDocument('1.0');????????$xmlDocument->preserveWhiteSpace?=?false;????????$xmlDocument->formatOutput?=?true;????????$xmlDocument->loadXML($xml->asXML(),LIBXML_NOERROR);????????$res?=?file_put_contents($filename,$xmlDocument->saveXML());????????return??$res?!==?false?true:$res;????}else{????????throw?new?\think\Exception('Incorrect?parameters');????}}

提示：上述方法基于thinkPHP的異常拋出，如果非thinkPHP框架記得自行修改上述代碼，以免報錯。我懶得改了。

11、uuid生成

生成UUID的格式：8-4-4-4-12

function?createUUID(){????$chars?=?md5(uniqid(mt_rand(),?true));????$uuid?=?substr?(?$chars,?0,?8?)?.?'-'????????.?substr?(?$chars,?8,?4?)?.?'-'????????.?substr?(?$chars,?12,?4?)?.?'-'????????.?substr?(?$chars,?16,?4?)?.?'-'????????.?substr?(?$chars,?20,?12?);????return?$uuid?;}12、計算兩個日期中間相差多少年多少月多少天多少小時function?diffTimes($stime=null){????$stime?=?emptyempty($stime)?time():strtotime($stime);????$now?=?time();????//$dateMonthOne?=?explode('-',?date('Y-m',?$stime));????//$dateMonthTwo?=?explode('-',?date('Y-m',?$now));????$diff?=?[];????$diff['hours']?=?($now?-?$stime)?/?(60?*?60);????//$diff['day']?=?($now?-?$stime)?/?(60?*?60?*?24);????//$diff['month']?=?abs($dateMonthOne[0]?-?$dateMonthTwo[0])?*?12?+?abs($dateMonthOne[1]?-?$dateMonthTwo[1]);????//$diff['year']?=?date('Y',?$now)?-?date('Y',?$stime);????return?intval($diff['hours']).'小時';}13、分鐘數轉時分function?min2hour($min){????$hours?=?intval($min/60);????$minutes?=?$min?%?60;????return?$hours.'小時'.$minutes.'分';}

14、時間友好展示

剛剛、幾分鐘前、幾天前、幾年前

function?mdate($time?=?NULL)?{????$text?=?'';????$time?=?$time?===?NULL?||?$time?>?time()???time()?:?intval($time);????$t?=?time()?-?$time;?//時間差?（秒）????$y?=?date('Y',?$time)-date('Y',?time());//是否跨年????switch($t){????????case?$t?==?0:????????????$text?=?'剛剛';????????????break;????????case?$t?<?60:????????????$text?=?$t?.?'秒前';?//?一分鐘內????????????break;????????case?$t?<?60?*?60:????????????$text?=?floor($t?/?60)?.?'分鐘前';?//一小時內????????????break;????????case?$t?<?60?*?60?*?24:????????????$text?=?floor($t?/?(60?*?60))?.?'小時前';?//?一天內????????????break;????????case?$t?<?60?*?60?*?24?*?3:????????????$text?=?floor($time/(60*60*24))?==1??'昨天?'?.?date('H:i',?$time)?:?'前天?'?.?date('H:i',?$time)?;?//昨天和前天????????????break;????????case?$t?<?60?*?60?*?24?*?30:????????????$text?=?date('m-d?H:i',?$time);?//一個月內????????????break;????????case?$t?<?60?*?60?*?24?*?365&&$y==0:????????????$text?=?date('m-d',?$time);?//一年內????????????break;????????default:????????????$text?=?date('Y-m-d',?$time);?//一年以前????????????break;????}????return?$text;}15、隱藏字符串中間一部分，用*代替function?hideStr($string,?$bengin=0,?$len?=?4,?$type?=?0,?$glue?=?'@')?{????if?(emptyempty($string))????????return?false;????$array?=?array();????if?($type?==?0?||?$type?==?1?||?$type?==?4)?{????????$strlen?=?$length?=?mb_strlen($string);????????while?($strlen)?{????????????$array[]?=?mb_substr($string,?0,?1,?'utf8');????????????$string?=?mb_substr($string,?1,?$strlen,?'utf8');????????????$strlen?=?mb_strlen($string);????????}????}????if?($type?==?0)?{????????for?($i?=?$bengin;?$i?<?($bengin?+?$len);?$i++)?{????????????if?(isset($array[$i]))????????????????$array[$i]?=?'*';????????}????????$string?=?implode('',?$array);????}else?if?($type?==?1)?{????????$array?=?array_reverse($array);????????for?($i?=?$bengin;?$i?<?($bengin?+?$len);?$i++)?{????????????if?(isset($array[$i]))????????????????$array[$i]?=?'*';????????}????????$string?=?implode('',?array_reverse($array));????}else?if?($type?==?2)?{????????$array?=?explode($glue,?$string);????????$array[0]?=?hideStr($array[0],?$bengin,?$len,?1);????????$string?=?implode($glue,?$array);????}?else?if?($type?==?3)?{????????$array?=?explode($glue,?$string);????????$array[1]?=?hideStr($array[1],?$bengin,?$len,?0);????????$string?=?implode($glue,?$array);????}?else?if?($type?==?4)?{????????$left?=?$bengin;????????$right?=?$len;????????$tem?=?array();????????for?($i?=?0;?$i?<?($length?-?$right);?$i++)?{????????????if?(isset($array[$i]))????????????????$tem[]?=?$i?>=?$left???'*'?:?$array[$i];????????}????????$array?=?array_chunk(array_reverse($array),?$right);????????$array?=?array_reverse($array[0]);????????for?($i?=?0;?$i?<?$right;?$i++)?{????????????$tem[]?=?$array[$i];????????}????????$string?=?implode('',?$tem);????}????return?$string;}

使用說明：

第一個參數是需要轉換的字符串；

第二個參數是隱藏的起始位置，當type=4時表示左側保留長度；

第三個參數是需要隱藏的字符串個數（長度）當type=4時表示右側保留長度；

第四個參數type取值所代表的意義：0，從左向右隱藏；1，從右向左隱藏；2，從指定字符位置分割前由右向左隱藏；3，從指定字符位置分割后由左向右隱藏；4，保留首末指定字符串。
