Question

PART 1: I need to create a loop for a set of array variables

for ($cnt=1; $cnt<=$qty; $cnt++) {
      $firstvar.$cnt['Code'] = '02';
      $secondvar.$cnt['Type'] = $somevar;
      $thirdvar.$cnt['Code'] = 'IN';
   }

// with a result of

      $firstvar1['Code'] = '02';
      $secondvar1['Type'] = $somevar;
      $thirdvar1['Code'] = 'IN';

      $firstvar2['Code'] = '02';
      $secondvar2['Type'] = $somevar;
      $thirdvar2['Code'] = 'IN';  

//etc.

However, the parsing of the $cnt variable seems to be conflicting with the array.

PART 2: I then need to create an array of variables like so:

  $lastvar['Thing'] = array( $thirdvar1, $thirdvar2, ... $thirdvar.$qty );

Here, creating a simple string using a for loop and placing it in the array doesn’t work.

THANKS!

Answer 1

PART 1: $firstvar.$cnt['Code'] should be ${"firstvar$cnt"}['Code'] (or ${'firstvar'.$cnt}['Code']).

PART 2:

for ($cnt=1; $cnt<=$qty; $cnt++) {
    $lastvar['Thing'][] = ${'thirdvar'.$qty};
}

PART 3: (mine!)
Put everything in the same loop:

for ($cnt=1; $cnt<=$qty; $cnt++) {
  ${'firstvar'.$cnt}['Code']  = 02;
  ${'secondvar'.$cnt}['Type'] = $somevar;
  ${'thirdvar'.$cnt}['Code']  = 'IN';
  $lastvar['Thing'][]         = ${thirdvar$qty};

}

Keep in mind that this code would be cleaner if you use arrays instead of variables names concatenation.
