  • I did not understand what you need to get in the end? overwrite file? to add? just iterate the data? - StereoFlo pm
  • It is necessary to take numbers from a file and substitute value1 = 1, value2 = 2, value3 = 20 in a cycle - Vladislav Ilichov

The simplest example. We get the data from the file.

  $data = file('file/path/t.txt');

Separate the data.

  $values = explode(' ', $data); list($value1, $value2, $value3) = $values

Perform a cycle and actions. The cycle will go from 0 to $value3 Namely, up to and including 20.

  for($i = 0; $i <= $value3; $i++) { //тут код }
