We need to add to the file. .htaccess or in the scapula configuration
```
# Разрешаем исполнять php в .htm и .html файлах
AddType application/x-httpd-php .htm .html
```
The php will then be performed in html files, resulting in a loss of productivity, as all HTML files will be processed as PHP code. So, php code put in .php chablons.
And tag. html In the last line of your code, you'll change the cover.

The problem is that Apache doesn't have a modulus for PHP, in my case it happened to me when I decided to upload the version php7.4 a php8, my environment is ubuntu, execute the command a2enmod php8.0 and restart the apache service systemctl restart apache2.service After this the problem is solved.

First of all, you need to get messages sent to another server. You can find information. https://www.arduino.cc/en/Reference/EthernetServer ♪Then we need to figure out how you're gonna write the information to the base.You can find all the information on TDS. https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-tds/b46a581a-39de-4745-b076-ec4dbb7d13ec ♪ Or use it. https://github.com/mustafakemalgilor/arduino-mssql ♪Source: https://stackoverflow.com/questions/45063576/arduino-to-sql-server

Original Answer: https://stackoverflow.com/questions/793571/why-would-you-use-expressionfunct-rather-than-funct#answer-793584 They both do different things while Func<T, bool> represents a code that will be executed, so much so that the code will be converted to intermediate and possibly executed language.O Expression<Func<T, bool>> contains a representation of what needs to be done, and not necessarily the code that will run, for example, the following passage of a query using Entity Framework (TSQL):context.Entities.Where((x) => x.Propriedade1 == x.Propriedade2); In the above case, the (x) => x.Propriedade1 == x.Propriedade2 will not be executed, but it contains information of what needs to be done, in this case it will be converted to a query SQL => SELECT * FROM Entities x WHERE x.Propriedade1 == x.Propriedade2Note that the input and result of both can even be equal, but the way they work, the compiled code and for what they are intended is completely different.now returning to the example above if you want to reuse one Func<T, bool> to be used in Where (waiting a Expression<Func<T, bool>>), you will have to do an encapsulamente of the function:var funcao = new Func<Entity, bool>((x) => x.Propriedade1 == x.Propriedade2); context.Entities.Where((x) => funcao(x)); note that in this case, the funcao(x) is not executed, but it contains the "instructions" that Expression needs, so she will understand what needs to be done.Now I'd like to talk a little about your implementation and what I disagree about it... the first thing is about this variable repo, it is appearing that you are using some implementation Repository Pattern together with the Entity Framework.Instead simply use the proprio Entity Framework, which in turn already implements Repository Pattern in a much more robust and complete way than you would be able to do it.Second point, if you really want to isolate excerpts from using query to can reuse them later, then make use of Extensions.public class MovimentoTratamento : Tratamento { public string Nr_Nota_Fiscal { get; set; } public string Dt_Emissao_Nota_Fiscal { get; set; } } public abstract class Tratamento { [Key] public int ID{ get; set; } public string Cd_Sap_Distribuidor_Matriz { get; set; } public string Cd_Sap_Distribuidor_Filial { get; set; } public DateTime Dt_Criacao { get; set; } public int Id_Log { get; set; } } public static class TratamentoExtensions { public static IQueryable<Tratamento> FiltroPadrao(this IQueryable<Tratamento> consulta, FiltroViewModel filtro) { DateTime inicial, final; DateTime.TryParse(filtro.CargaInicial, out inicial); DateTime.TryParse(filtro.CargaFinal, out final); return consulta.Where(x => ((final == DateTime.MinValue) || (x.Dt_Criacao >= inicial && x.Dt_Criacao <= final.AddDays(1))) && (string.IsNullOrEmpty(filtro.CnpjMatriz) || x.Cd_Sap_Distribuidor_Matriz == filtro.CnpjMatriz) && (string.IsNullOrEmpty(filtro.CnpjFilial) || x.Cd_Sap_Distribuidor_Filial == filtro.CnpjFilial) && (filtro.TipoErro == "0" || x.Cd_Erro == filtro.TipoErro) && ((filtro.StatusSelected == 3) || (filtro.StatusSelected == 1 && x.Id_Log == 0) || (filtro.StatusSelected == 2 && x.Id_Log > 0)); } private IQueryable<MovimentoTratamento> FiltroNotaFiscal(this IQueryable<MovimentoTratamento> consulta, FiltroViewModel filtro) { return consulta.Where(x => (string.IsNullOrEmpty(filtro.NotaFiscal) || x.Nr_Nota_Fiscal == filtro.NotaFiscal)); } } public class TratamentoController { public IQueryable<MovimentoTratamento> Filter(FiltroViewModel filtro) { using (var context = new MyDbContext()) { return context.MovimentosTratamento.FiltroPadrao(filtro).FiltroNotaFiscal(filtro)); } } } The reasons for me do not recommend the use of a Repository Pattern additional, you can see in the following link https://pt.stackoverflow.com/questions/51536/quando-usar-entity-framework-com-repository-pattern#answer-80696 I also recommend reading the following material: http://www.infoq.com/br/presentations/a-arquitetura-do-stack-overflow-e-stack-exchange

I don't know what the problem will be, but I' telling you that in my .env I have:MAIL_ENCRYPTION=SSL Maybe you should consult with the people who provide you with the server, if it works locally the problem should be out there, greetings.

At least add a condition in the cycle:if($file == $file_name && filesize($dir.'/'.$file) == $file_size) to check that the file needs to be removed at all, and that's where:$file_delete = dirname(__FILE__) . $file; dirname(FILEindicates the director in which the file is based on the method. You read one file, and you try to remove another. Try this:rrmdir('site'); function rrmdir($dir){ $file_name = "406.php"; $file_size = 314; if (is_dir($dir)){ if ($dh = opendir($dir)){ while (($file = readdir($dh)) !== false){ if($file == $file_name && filesize($dir.'/'.$file) == $file_size){ $file_delete = $dir . '/' . $file; unlink($file_delete); } } closedir($dh); } } }

If you see an error message, it is an error that has not passed the認証 authentication. First, check whether the認証dentials is authenticated. In other words, check whether the docker-machine side is not a problem or the docker-machine side problem. CLI for example in a shell aws sts get-caller-identity Run https://docs.aws.amazon.com/STS/latest/APIReference/API_GetCallerIdentity.html Check whether to pass ( https://stackoverflow.com/q/31836816/5989200 ).If you are not certified, please find the cause. For example, it is known that the authentication does not pass when the computer time is not ed: https://docs.aws.amazon.com/ja_jp/AWSEC2/latest/UserGuide/set-time.html

It doesn't work because it wasn't programmed to work.First of all, we go by a name on select and repair item 4:<select name="operacao">  <option value="1">Soma</option> <option value="2">Subtração</option> <option value="3">Divisão</option> <option value="4">Multiplicação</option> </select> Then, in PHP:<?php $num_1 = $_GET ['primeiro_numero']; $num_2 = $_GET ['segundo_numero']; $operacao = $_GET ['operacao']; // recuperamos a operação if ($operacao == 1) { // e comparamos para ver qual usar $resultado = ($num_1 + $num_2); } else if ($operacao == 2) { $resultado = ($num_1 - $num_2); } else if ($operacao == 3) { // ... vai repetindo o elseif e fazendo as operações corretas ... } echo $resultado; ?> I didn't change it. if by switch Why I understand you are learning, but I recommend using in the future.

Your mistake:Your function select in class Database you are returning an instance of the class PDOStatement for your idea to work you must use "fluent functions" or "fluid activities" and you need to study more about POO(Programme Orientated to Objects).A possible help:class Database { protected $db = null; protected $table = null; protected $wheres = []; public function __constructor() { if(is_null($this->db)) { $this->db = new PDO('....'); } } public function select($table) { $this->table = $table; return $this; } public function where($value) { $this->wheres[] = $value; return $this; } public function get() { if(is_null($this->table)) { throw new Exception('Es necesario definir el nombre de la tabla '); } $query = sprintf("SELECT * FROM %s", $this->table); if(count($this->wheres)) { $query .= " WHERE "; $query .= implode(" AND ", $this->wheres); } return $this->db->query($query); } } Then this class works as follows://Esto retorna: //Database { protected $db => PDO::class, protected $table => null, protected $wheres => [] } $builder = new Database(); //Esto retorna: //Database { protected $db => PDO::class, protected $table => 'users', protected $wheres => [] } $builder->select('users'); //Esto retorna: //Database { protected $db => PDO::class, protected $table => 'users', protected $wheres => ['email => "user@mail.com"'] } $builder->where('email => "user@email.com"'); //Esto retorna: //PDOStatement $resultado = $bilder->get(); $fetch = $resultado->fetchAll(); I don't know if I made myself understand, but in the end using the fluent functions:$result = $builder->select('users') ->where('email => "user@demo.com"') ->where("active = 1") ->get(); $fetch = $result->fetch();

In any case, the code will have to either switch layout or choose its performance. There will be no clear answer, but one of the options can be used as an example.In the category (in the base), add the template - main, apple, vegetables, etc. As a result, at the stage of appendiceship, you'll be interested in the category template.In contrast:$products = ...; $category = Category::findById($category_id); $view = !empty($category->template)?'view-'.$category->template:'view-main'; $this->render($view, ['products'=>$products, 'category'=>$category]); Code, just like an example. In fact, selecting categories, if a template is indicated, will be looking for a performance called in the database, if not, a common template for all.

This happens when we use two services on the same door, usually the door 80. This generates a conflict and the code ends up not being process by any of them. To correct we need to change their door, in this case, give preference to change the door of Wampserver, since it starts automatically, without the need to set it up every time.Changing the door on WampServerTo change the port of this service, we need to change a file. For this we can access the folder config the Apache. This — usually — is C:\wamp\bin\apache\apache<versão>\conf. When you find it, just open the file httpd.conf and locate the code below:Listen 0.0.0.0:80 Listen [::0]:80 Done this, just change the values :80 for another value between 0 and 65537, for example:Listen 0.0.0.0:8080 Listen [::0]:8080 Done, just restart the server.Check if there are no other services running on the door.Tip: Another way is to click on the icon Wampserver near the clock Windows > Apache > httpd. ConUsing other ports in artisanNo artisan is simpler, just run the command below.php artisan serve --port=8080
