项目开发常用业务逻辑代码
项目开发中经常用到的业务逻辑代码,总结在此处,备用。
1、加密解密函数:
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 $encrypted; } }
在使用的时候我们可以为加密的字符串,设置一个加密KEY值,解密的时候传入这个KEY值即可获得密文原文。$decrypt取值0和1时分别对应加密、解密。
2、上传图片方向纠正:
由于每个人拍照姿势都不一样,难免有人拍照上传的图片出现倒立的情况,下面这个业务逻辑可以自动纠正上传图片的方向。
$image = imagecreatefromstring(file_get_contents($_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 $fullname 全名(如:百里屠苏) * @return array 一维数组[0=>'姓氏',1=>'名称'] * @return array */ function splitName($fullname){ $hyphenated = array( '百里','北堂','北野','北宫','辟闾', '淳于','成公','陈生','褚师','城池', '端木','东方','东郭','东野','东门','第五','大狐','段干','段阳','第二','东宫', '公孙','公冶','公羊','公良','公西','公孟','公伯','公析','公肩','公坚','公乘','公皙','公户','公广','公仪','公祖','公玉','公仲','公上','公门','公山','高堂','高阳','郭公','谷梁','毌将','毌丘','单于','叱干','叱利','车非', '独孤','大野','独吉','达奚','东里', '哥舒','贯丘', '皇甫','黄龙','胡母','何阳','赫连','呼延','贺兰','贺若','黑齿','斛律','斛粟', '夹谷','九方','即墨','吉胡', '可频', '梁丘','闾丘','洛阳','陵尹','冷富','龙丘','令狐', '慕容','万俟','抹捻', '纳兰','南荣', '南宫','南郭','女娲','南伯','南容','南门','南野', '欧阳','欧侯', '濮阳','普周','仆固','仆散','蒲察', '青阳','漆雕','亓官','渠丘','屈突','屈卢','钳耳', '壤驷','汝嫣', '上官','少室','少叔','司徒','司马','司空','司寇','士孙','申屠','申徒','申鲜','申叔','夙沙','叔先','叔仲','叔孙','侍其','是云','索卢','厍狄', '澹台','太史','太叔','太公','屠岸','唐古','拓跋','同蹄','秃发', '闻人','巫马','微生','王孙','无庸','完颜', '夏侯','西门','信平','鲜于','轩辕','相里','新垣','徐离姓', '羊舌','羊角','延陵','於陵','伊祁','吾丘','乐正','宇文','尉迟','耶律', '诸葛','颛孙','仲孙','仲长','钟离','宗政','主父','中叔','左人','左丘','宰父','长儿','仉督','长孙','子车','子书','子桑' ); $vLength = mb_strlen($fullname, 'utf-8'); $lastname = ''; $firstname = '';//前为姓,后为名 if($vLength > 2){ $preTwoWords = mb_substr($fullname, 0, 2, 'utf-8');//取命名的前两个字,看是否在复姓库中 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){//全名只有两个字时,以前一个为姓,后一下为名 $lastname = mb_substr($fullname ,0, 1, 'utf-8'); $firstname = mb_substr($fullname, 1, 10, 'utf-8'); }else{ $lastname = $fullname; } return array($lastname, $firstname); }
4、打印输出数据到文件
/** * 打印输出数据到文件 * @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, $str, FILE_APPEND); }
这个函数虽然很小巧,但是在调试一些内部执行数据的时候非常有用,且很方便的输出我们要查看的数据。
5、随机字符生成
/* * 随机字符生成 */ function randStr($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)
6、生成唯一订单号
/* * 生成唯一订单号 */ function CreateOrderId(){ $order_id_main = date('YmdHis') . rand(10000000,99999999); //订单号码主体长度 $order_id_len = strlen($order_id_main); $order_id_sum = 0; for($i=0; $i
7、获取毫秒级时间戳。
关于获取毫秒级时间戳其实只需要一行代码,网上很多人专门写了很多函数去处理。因为毫秒级的时间戳是13位,int类会溢出。操作使用时可以以float类型或string类型均可。
$timestamp = substr(microtime(true)*1000,0,13);
8、获取文章中的图片
/* * 获取文章图片 */ function getContentPic($content,$num='1'){ $pattern="//"; preg_match_all($pattern,htmlspecialchars_decode($content),$match); if(!emptyempty($match[1]) && $num == 1){ return $match[1][0]; }else{ return $match[1]; } return ''; }
9、重写PHP array_push实现自由添加数组键值
/* * 重写array_push * @param $array array 目标数组 * @param $value mix 键值 * @param $position int 索引位置 * @param $key string 键名 * @return Array */ function array_push_position(&$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文件节点
(可以很方便的生成网站地图,方便SEO优化)
/* * Xml文件增加节点 * @param $filename string 文件路径 * @param $data array 追加数组 * @param $nodename string 节点名称 * @return boole */ function addXmlNode($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 thinkException('Incorrect parameters'); } }
提示:上述方法基于thinkPHP的异常抛出,如果非thinkPHP框架记得自行修改上述代码,以免报错。我懒得改了。
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 $uuid ; }
12、计算两个日期中间相差多少年多少月多少天多少小时
function diffTimes($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'])."小时"; }
13、分钟数转时分
function min2hour($min){ $hours = intval($min/60); $minutes = $min % 60; return $hours."小时".$minutes."分"; }
14、时间友好展示
刚刚、几分钟前、几天前、几年前
function mdate($time = NULL) { $text = ''; $time = $time === NULL || $time > time() ? time() : intval($time); $t = time() - $time; //时间差 (秒) $y = date('Y', $time)-date('Y', time());//是否跨年 switch($t){ case $t == 0: $text = '刚刚'; break; case $t
15、隐藏字符串中间一部分,用*代替
function hideStr($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 = $left ? "*" : $array[$i]; } $array = array_chunk(array_reverse($array), $right); $array = array_reverse($array[0]); for ($i = 0; $i
使用说明:
第一个参数是需要转换的字符串;
第二个参数是隐藏的起始位置,当type=4时表示左侧保留长度;
第三个参数是需要隐藏的字符串个数(长度)当type=4时表示右侧保留长度;
第四个参数type取值所代表的意义:0,从左向右隐藏;1,从右向左隐藏;2,从指定字符位置分割前由右向左隐藏;3,从指定字符位置分割后由左向右隐藏;4,保留首末指定字符串。
第五个参数是分隔符。
16、二维数组按指定键排序
function array_msort($array, $cols) { $colarr = array(); foreach ($cols as $col => $order) { $colarr[$col] = array(); foreach ($array as $k => $row) { $colarr[$col]['_'.$k] = strtolower($row[$col]); } } $eval = 'array_multisort('; foreach ($cols as $col => $order) { $eval .= '$colarr[''.$col.''],'.$order.','; } $eval = substr($eval,0,-1).');'; eval($eval); $ret = array(); foreach ($colarr as $col => $arr) { foreach ($arr as $k => $v) { $k = substr($k,1); if (!isset($ret[$k])) $ret[$k] = $array[$k]; $ret[$k][$col] = $array[$k][$col]; } } return $ret; }
17、Base64图片流转图片文件
function saveBase64Image($base64_image_content,$image_path){ if (preg_match('/^(data:s*image/(w+);base64,)/', $base64_image_content, $result)){ //图片后缀 $type = $result[2]; if($type=='jpeg'){ $type='jpg'; } //保存位置--图片名 $image_name=date('His').str_pad(mt_rand(1, 99999), 5, '0', STR_PAD_LEFT).".".$type; //$image_path = '/static/upload/quanzi/'.$memberid.'/image/'; $image_url = $image_path.$image_name; if(!is_dir(ROOT_PATH.$image_path)){ mkdir(ROOT_PATH.$image_path,0755,true); } //解码 $decode=base64_decode(str_replace($result[1], '', $base64_image_content)); if (file_put_contents(ROOT_PATH.$image_url, $decode)){ $data['code']='0'; $data['imageName']=$image_name; $data['image_url']=$image_url; $data['type']=$type; $data['msg']='保存成功!'; }else{ $data['code']='1'; $data['imgageName']=''; $data['image_url']=''; $data['type']=''; $data['msg']='图片保存失败!'; } }else{ $data['code']='1'; $data['imgageName']=''; $data['image_url']=''; $data['type']=''; $data['msg']='base64图片格式有误!'; } return $data; }
18、随机昵称

19、去除文本中指定的HTML标签
function strip_selected_tags($text, $tags = array()){ $args = func_get_args(); $text = array_shift($args); $tags = func_num_args() > 2 ? array_diff($args,array($text)):(array)$tags; foreach ($tags as $tag){ if(preg_match_all('/]*>(.*)/iU', $text, $found)){ $text = str_replace($found[0],$found[1],$text); } } return $text; }
20、人民币金额友好显示:多少万、多少亿
function transnum($num,$type){ //type:1单位个 2单位万 $result = array(); $leng = pow(10,2);//小数位修改最后一个数字 switch($type){ case 1: if($num >= 10000){ $result['num'] = intval(($num/10000)*$leng)/$leng; if($result['num'] >= 10000){ $result['num'] = intval(($num/100000000)*$leng)/$leng; $result['rem'] = "亿"; }else{ $result['rem'] = "万"; } }else{ $result['num'] = intval($num*$leng)/$leng; $result['rem'] = ""; } break; case 2: if($num >= 10000){ $result['num'] = intval(($num/10000)*$leng)/$leng; $result['rem'] = "亿"; }else{ $result['num'] = intval($num*$leng)/$leng; $result['rem'] = "万"; } break; } return $result['num'].$result['rem']; }
21、二维数组去重
/** * 去掉二维数组中的重复项 * @param $array2D 数组 * @param $keyArray 还原时字段对应的key * @return array 去掉了重复项的数组 */ function array_unique_fb($array2D,$keyArray){ $temp=array(); foreach ($array2D as $v){ $v = join(",",$v); //降维,也可以用implode,将一维数组转换为用逗号连接的字符串 $temp[] = $v; } $temp = array_unique($temp); //去掉重复的字符串,也就是重复的一维数组 foreach ($temp as $k => $v){ //$temp[$k] = explode(",",$v); //再将拆开的数组重新组装 $temp[$k]= array_combine($keyArray ,explode(",",trim($v))); } return $temp; }
