set_string_to_file

set_string_to_file($file,$str,$line,$add=true,$timeout=COMMAND_TIME); - set (change or add) the specified string in the file

The function accepts parameters as input:

$file – path to the file where the string should be set. It can be either absolute or relative (relative to the script folder).

$str – the string to set in the file

$line – the number of the specified line in the file (line numbering, as everywhere, starts from zero)

$add – the string will be added to the file (true) or replace the old string (false)

$timeout – the maximum time to perform this operation (in seconds), by default - 60 seconds, if the operation is not completed during this time, the script continues to run further.

After testing, the function returns the result of its work to the script :

true – operation completed (boolean)

false – operation failed (boolean)

PHP example:

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

$file = "test \ test_insert.txt";
$file_os->delete($file);

//1
echo("1.Add lines to the beginning of the file file: 
 
");
for($i = 0; $i <5; $i ++)
echo($textfile->set_string_to_file($file, "line #" + $i + " n", 0)."
");

//2
echo("
 2.Replace the line at the beginning of file: 
 
");
echo($textfile->set_string_to_file($file, "line # 100  n", 0, false)."
");

//show the result
$app->shell_execute("", $file);

//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("
  textfile.xxxxxxxxx  ")

file = "test \ test_insert.txt"
file_os.delete(file)

# 1
echo("1.Add lines to the beginning of file: 
 
")
for i in range(0,4):
echo(textfile.set_string_to_file(file, "line #" + str(i) + "
", 0)," 
 ")

# 2
echo("
 2.Replace the line at the beginning of file: 
 
")
echo(textfile.set_string_to_file(file, "line # 100
", 0, false)," 
 ")

# show the result
app.shell_execute("", file)

# end
echo("
 
")

# Quit
app.quit()
