is_exist

is_exist($path); - this function is used to check the existence of the specified folder

The function accepts parameters as input:

  • $path – path to the folder to check for (string). It can be either absolute or relative (relative to the script folder).

    After testing, the function returns the result of its work to the script :
  • true – this folder exists (boolean)
  • false – there is no such folder (boolean)

    PHP example:

    <?php $xhe_host = "127.0.0.1:7010";
     
    //connect the object to control the emulator, if not already connected
    if(!isset($path))
       $path = "../../../Templates/xweb_human_emulator.php";
    require($path);
     
    //Start
    echo "<hr> <font color = blue> folder->".basename(__FILE__)."</font> <hr>";
     
    //1
    echo "1.Check the directory that there is a directory test1 in the folder where the script is located:";
    echo $folder->is_exist("test1")."<br>";
     
    //end
    echo "<hr> <br>";
     
    //Quit
    $app->quit();
    ?>

    Python example:

    # Additional paths
    import sys
    sys.path.insert(0, '../../../Templates PY/')
     
    xhe_host = "127.0.0.1:7011"
    from xweb_human_emulator import *
     
    # Start
    echo("<hr> <font color = blue> folder.xxxxxxxxx </font> <hr>")
     
    # 1
    echo("1.Check the directory that there is a directory test1 in the folder where the script is located:")
    echo(folder.is_exist("test1"), "<br>")
     
    # end
    echo("<hr> <br>")
     
    # Quit
    app.quit()

    C# example:

    #region using
     
    using System;
    using System.Diagnostics;
    using System.Collections.Generic;
    using System.Linq;
    using System.IO;
    using System.Text;
    using System.Threading;
     
    using XHE;
    using XHE.XHE_DOM;
    using XHE.XHE_System;
    using XHE.XHE_Window;
    using XHE.XHE_Web;
     
    #endregion
     
      class Program: XHEScript
      {
    static void Main(string [] args)
    {
    //init XHE
    server = "127.0.0.1:7010";
    InitXHE();
     
    //Start
    echo("<hr> <font color = blue> folder.is_exist </font> <hr>");
     
    //1 step
    echo("1.Check the directory that there is a directory test1 in the folder where the script is located:");
    echo(folder.is_exist("test1") + "<br>");
     
    //end
    echo("<hr> <br>");
     
    app.quit();
    }
    }

    Java Script example:

    //connect the object to control the emulator, if not already connected
    xhe_host = "127.0.0.1:7010";
    echo = require("../../../Templates JS/xweb_human_emulator.js");
     
    //Start
    echo("<hr> <font color = blue> folder.is_exist </font> <hr>");
     
    //1 step
    echo("1.Check the directory that there is a directory test1 in the folder where the script is located:");
    echo(folder.is_exist("test1") + "<br>");
     
    //end
    echo("<hr> <br>");
     
    //Quit
    app.quit();
