How do I add data from a PHP form into an array?

If I have a loop that requests my data from my form:

for ($i=0;$i < count($_POST['checkbx']);$i++)
    {
    // calculate the file from the checkbx
    $filename = $_POST['checkbx'][$i];
    $clearfilename = substr($filename, strrpos ($filename, "/") + 1);

     echo "'".$filename."',";       

    }

how do I add that into the sample array below?:

$files = array( 'files.extension', 'files.extension', );

• Probably like this:

  for ($i=0;$i < count($_POST['checkbx']);$i++) {
  // calculate the file from the checkbx
  $filename = $_POST['checkbx'][$i];
  $clearfilename = substr($filename, strrpos ($filename, "/") + 1);
  
  $files[] = $filename; // of $clearfilename if that's what you wanting the in the array  
  }
  

• $files[] =$filename;
  

  OR

  array_push($files, $filename);
  

• Remember that you also need to name these checkboxes in HTML with "[]" after their names. e.g.:

  <input type="checkbox" name="checkbx[]"  ...etc... >
  

  You will then be able to access them thusly:

  <?php
  
  // This will loop through all the checkbox values
  for ($i = 0; $i < count($_POST['checkbx']); $i++) {
     // Do something here with $_POST['checkbx'][$i]
  }
  
  ?>
  

• I'm not entirely sure what you want to add to that array, but here is the general method of 'pushing' data into an array using php:

  <?php
  $array[] = $var;
  ?>
  

  for example you could do:

  for ($i=0;$i < count($_POST['checkbx']);$i++)
  {
     // calculate the file from the checkbx
     $filename = $_POST['checkbx'][$i];
     $clearfilename = substr($filename, strrpos ($filename, "/") + 1);
  
     echo "'".$filename."',";       
     $files[] = $filename;
  }
  

• Even smaller:

  $files = array();
  foreach($_POST['checkbx'] as $file)
  {
      $files[] = basename($file);
  }
  

  If you aren't absolutely sure that $_POST['checkbx'] exists and is an array you should prolly do:

  $files = array();
  if (is_array(@$_POST['checkbx']))
  {
      foreach($_POST['checkbx'] as $file)
      {
          $files[] = basename($file);
      }
  }
  

• You can use the array_push function :

  <?php
  $stack = array("orange", "banana");
  array_push($stack, "apple", "raspberry");
  print_r($stack);
  ?>
  

  Will give :

  Array
  (
      [0] => orange
      [1] => banana
      [2] => apple
      [3] => raspberry
  )
  

  Simply fill the array using array_push for each file.
