这篇文章主要为大家介绍了常用PHP业务逻辑的demo总结，有需要的朋友可以借鉴参考下，希望能够有所帮助，祝大家多多进步，早日升职加薪
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)<$len)
$password.=substr($chars,(mt_rand()%strlen($chars)),1);
return $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; $i<$order_id_len; $i++){
$order_id_sum += (int)(substr($order_id_main,$i,1));
}
//唯一订单号码（YYYYMMDDHHIISSNNNNNNNNCC）
$order_id = $order_id_main . str_pad((100 - $order_id_sum % 100) % 100,2,'0',STR_PAD_LEFT);
return $order_id;
}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'){
$pattern="/<img.*?src=[\'|\"](.*?)[\'|\"].*?[\/]?>/";
preg_match_all($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 \think\Exception('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 < 60:
$text = $t . '秒前'; // 一分钟内
break;
case $t < 60 * 60:
$text = floor($t / 60) . '分钟前'; //一小时内
break;
case $t < 60 * 60 * 24:
$text = floor($t / (60 * 60)) . '小时前'; // 一天内
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); //一个月内
break;
case $t < 60 * 60 * 24 * 365&&$y==0:
$text = date('m-d', $time); //一年内
break;
default:
$text = date('Y-m-d', $time); //一年以前
break;
}
return $text;
}15、隐藏字符串中间一部分，用*代替
function hideStr($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; $i < ($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

}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;
