As by C # in WindowsFormsApplication call a function from a php page and pick up the value from it, eg:
page php:
function retornar()
{
$valor = "aa";
return $valor;
}
In case I would like to call this page through C # and assign a value of C # to the value that will come, in case "aa".
If it's a "php page" then I suppose you're talking about a web page anyway, so in practice you should call the function on your webpage, for example teste.php :
<?php
function retornar() {
$valor = "aa";
return $valor;
}
echo retornar();
Or it may even be just this:
<?php
echo "aa";
And then call the address http://seusite/teste.php (yourite is just an example) in your own C # , you can use #
Call in your C # file
WebClient client = new WebClient();
string downloadString = client.DownloadString("http://seusite/teste.php");
Or save content in a document:
WebClient client = new WebClient ();
client.DownloadFile("http://seusite/teste.php", " C:\conteudo.txt");
According to what I researched, in C # you can execute whatever you want in the command line as follows:
string strCmdText;
strCmdText= "/C copy /b Image1.jpg + Archive.rar Image2.jpg";
System.Diagnostics.Process.Start("CMD.exe",strCmdText);

Since you can run commands on your PC, instead of accessing a URL you can run PHP code through the interpreter that comes with PHP5 +. It would just be the case that you run your .php file straight from the command line, hence you will not need a server running the desired program. You can even pass arguments directly to this command line, and reference them inside PHP through the $ argc (number of arguments) and $ argv (the arguments themselves, in string) objects.
