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: 

    <?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> textfile->".basename(__FILE__)."</font> <hr>";
 
$file = "test \ test_insert.txt";
$file_os->delete($file);
 
//1
echo("1.Add lines to the beginning of the file file: <br> <br>");
for($i = 0; $i <5; $i ++)
echo($textfile->set_string_to_file($file, "line #" + $i + " n", 0)."<br>");
 
//2
echo("<br> 2.Replace the line at the beginning of file: <br> <br>");
echo($textfile->set_string_to_file($file, "line # 100  n", 0, false)."<br>");
 
//show the result
$app->shell_execute("", $file);
 
//end
echo "<hr> <br>";
 
//Quit
$app->quit();
?>

for i in range(0,4):
