安装
在composer.json中添加
"thefunpower/helper": "dev-main"
助手工具类或函数
需要定义PATH目录，项目的根目录
define("PATH",__DIR__.'/');
需要定义WWW_PATH目录，网站访问的目录，有时PATH与WWW_PATH是一样的
define("WWW_PATH",__DIR__.'/');
确保有data uploads两个目录且可写.
data在根目录 uploads在网站访问的目录

RPC
服务端
class ServerGetUser{
public function getInfo($name = 'abc'){
return ['welcome'=>$name,'token'=>rpc_token()];
}
}
rpc_server("ServerGetUser");
客户端
$client = rpc_client("http://127.0.0.1:5000/rpc.php");
$info = $client->getInfo("test");
print_r($info);
Ftp
php.ini中开启ftp扩展
把本地文件同步到FTP上。
如果FTP上目录文件已存在，将会被替换。
use helper_v3Ftp;
$ftp = Ftp::start([
'host' =>'IP地址',
'user' =>'帐号',
'pwd' =>'密码',
'port' =>'端口，默认21',
]);
//上传到根目录
Ftp::put_all(__DIR__.'/uploads');
//或上传到指定目录
//Ftp::put_all(__DIR__.'/uploads','uploads');
Ftp::end();

HTML转PDF
安装依赖
yum install xorg-x11-server-Xvfb wkhtmltopdf fontconfig freetype wqy-zenhei-fonts wqy-microhei-fonts
PHP中调用
html_to_pdf($input_html_file,$output_pdf_file,$return_cmd = false,$exec = false)
如遇条形码可用 php-barcode-generator
composer require picqer/php-barcode-generator
Xls
composer require phpoffice/phpspreadsheet
当前使用 "phpoffice/phpspreadsheet": "^1.20"
生成xls
use helper_v3Xls;
$all = db_get("catalog_product",'*');
foreach($all as $v){
$title = $v['title'];
$desc = $v['desc'];
$values[] = [
'title'=>$title,
'desc'=>$desc,
];
}
Xls::create([
'title'=>'编号',
'desc'=>'规格',
], $values, 'product', FALSE);
第一个worksheet
Xls::$label = $txt_month.'专票';
Xls::$sheet_width = [
'A' => "15",
'B' => "36",
'C' => "30",
'D' => "10",
'E' => "10",
'F' => "10",
];
更多worksheet
Xls::$works = [
[
'title' => $title,
'label' => $txt_month.'普票',
'data' => $new_data,
'width' => Xls::$sheet_width,
]
];
合并
Xls::$merge = [
'A18:E22'
];
Xls::create($title, $values, $name, FALSE);
消息订阅
依赖
yarn add ioredis
yarn add ws
1.生成server.js
echo create_node_ws_server($ws_port=3006,$topic=['demo'],$redis_host='127.0.0.1',$port='6379',$auth='');
复制代码至server.js中
启动server
node server.js
2.HTML添加监听
依赖 reconnecting-websocket.js
https://github.com/joewalnes/reconnecting-websocket
<script>
<?php
$func = "
data = JSON.parse(data);
console.log(data);
";
echo get_ws_js($func,'ws://127.0.0.1:3006');
?>
</script>
其中ws://127.0.0.1:3006 如果是 wss 则wss://yourdomain/wss
3.php发送消息
redis_pub("demo",['title'=>'yourname']);
如使用wss则需配置Nginx转发
location /wss {
proxy_pass http://127.0.0.1:3006;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
rewrite /wss/(.*) /$1 break;
proxy_redirect off;
}
测试
redis_sub("demo",function($channel,$message){
echo "channel ".$channel."n";
print_r($message);
});
pusher
https://pusher.com/
PUSHER_APP_KEY =
PUSHER_APP_SECRET =
PUSHER_APP_ID =
PUSHER_APP_CLUSTER =
前端需要加载JS
<script src="https://js.pusher.com/8.0.1/pusher.min.js"></script>
<script type="text/javascript">
var pusher = new Pusher("<?=get_config("PUSHER_APP_KEY")?>", {
cluster: "<?=get_config("PUSHER_APP_CLUSTER")?>",
});
var channel = pusher.subscribe("netteadmin");
channel.bind("notice", (data) => {
console.log(data);
});
</script>
发送消息
helper_v3Pusher::sender($channel,$event,$data = []);
或使用
send_pusher($data = [],$channel='netteadmin',$event='notice');
xcookie 加密
//设置
xcookie("ss",1);
xcookie("ss",['title'=>'tt']);
//读取
pr(xcookie("ss"));
//删除
xcookie_delete("ss");
redis锁
global $redis_lock;
//锁前缀
global $lock_key;
$redis_lock = [
'host'=>'',
'port'=>'',
'auth'=>'',
];
lock_call('k',functon(){
},second);
gz压缩数据
$s = gz_encode(['a'=>"test"]);
echo $s;
echo "解压后<br>";
print_r(gz_decode($s));
SCSS
scss链接
<link rel="stylesheet" href="<?=scss("app.scss",true)?>" />
也可以直接调用
<style>
<?php
echo scss("
$color: #abc;
div { color: lighten($color, 20%); }
");
<?php }?>
</style>
scss文件语法，参考 http://www.uinio.com/Web/Scss/
$color: red;
.navigation {
ul {
line-height: 20px;
color: blue;
a {
color: $color;
}
}
}
.footer {
.copyright {
color: silver;
}
}
