helper

https://github.com/thefunpower/helper

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

Predis Publish Subscribe

连接

predis($host,$port,$auth);

发布消息

redis_pub("demo","welcome man");
redis_pub("demo",['title'=>'yourname']);

取订阅消息

redis_sub("demo",function($channel,$message){
  echo "channel ".$channel."\n";
  print_r($message);
});

Predis GEO

连接

predis($host,$port,$auth);

获取

$s = predis_geo_pos('places',[
    '上海外滩','北京天安门' 
]); 
pr($s) ;

添加

predis_add_geo('places',[
    [ 
        'lat'=>'116.397128',
        'lng'=>'39.916527',
        'title'=>'北京天安门'
    ],
    [

        'lng'=>'31.21706',
        'title'=>'襄阳公园'
    ], 
]);

附近分页

pr(predis_get_pager('places', 121.45668, 31.21706));

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_v3\Ftp;
$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();

            )
        2是横版，1是竖版
        [dimensions_type] => 2
    )

取PDF页数

Pdf::get_pages($file);

设置PDF信息

其中arr支持title author keywords

生成PDF table

$html = '
<style> 
table{
    width: 100%;
    text-align:left;
    margin: 0 auto;
    border: 1px solid #000000;
    border-collapse: collapse;

    text-align: center;
}
</style>
<table   cellspacing="0" cellpadding="0" border="0"   >
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">First</th>
      <th scope="col">Last</th>
      <th scope="col">Handle</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">1</th>
      <td>Mark</td>
      <td>Otto</td>
      <td>@mdo</td>
    </tr>
    <tr>
      <th scope="row">2</th>
      <td>Jacob</td>
      <td>Thornton</td>
      <td>@fat</td>
    </tr>
    <tr>
      <th scope="row">3</th>
      <td colspan="2">Larry the Bird</td>
      <td>@twitter</td>
    </tr>
  </tbody>
</table>';
    $mpdf = Pdf::init();
    $mpdf->shrink_tables_to_fit = 1;
    $mpdf->WriteHTML($html);
    $mpdf->Output();

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_v3\Xls;

$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_v3\Pusher::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;
    }
}
