is_exist

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

The function accepts parameters as input:

$path – path to the file 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 – there is such a file (boolean)

false – there is no such file (boolean)

PHP example:

  file_os->".basename(__FILE__)." ";

//1
echo "1.Check if the specified file exists:";
echo $file_os->is_exist("test \ test1.txt")."
";

//end
echo "
 
";

//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("
  file_os.xxxxxxxxx  ")

# 1
echo("1.Check if the given file exists:")
echo(file_os.is_exist("test \ test1.txt"), "
")

# end
echo("
 
")

# Quit
app.quit()
