get_random_file

get_random_file($folder,$extension,$flag_inc_subfolders); - this function is used to get a random file path in the specified folder

The function accepts parameters as input:

  • $folder – path to the folder where the file will be searched (string). It can be either absolute or relative (relative to the script folder).
  • $extension – file extension, among which you can choose
  • $flag_inc_subfolders – whether to include subfolders in the search area (true - include, false - do not include) .

    After testing, the function returns the result of its work to the script :
  • file path – the path to a randomly selected file in the specified folder (string)
  • 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.Get a random path to a file like txt or php from the directory: test1:";
echo $folder->get_random_file("test1", "txt; php", false)."<br>";
 
//2
echo "2.Get a random path to a txt file from the directory: test1 and its subdirectories:";
echo $folder->get_random_file("test1", "txt", true)."<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.Get a random path to a file like txt or php, from the directory: test1:")
echo(folder.get_random_file("test1", "txt; php", false), "<br>")
 
# 2
echo("2.Get a random path to a txt file from the directory: test1 and its subdirectories:")
echo(folder.get_random_file("test1", "txt", true), "<br>")
 
# end
echo("<hr> <br>")
 
# Quit
app.quit()
