警告：第162行在PHP中被零除

Question

I have this error on my site:

ERR (3): Warning: Division by zero in public_html/app/code/community/VES/PdfProProcessor/Pdf/include/table_frame_reflower.cls.php on line 162

at that line I have the following code:

  $increment = 0;

  // Case 1:
  if ( $absolute_used == 0 && $percent_used == 0 ) {
    $increment = $width - $min_width;

    foreach (array_keys($columns) as $i) {
      $cellmap->set_column_width($i, $columns[$i]["min-width"] + $increment * ($columns[$i]["max-width"] / $max_width));
    }
    return;
  }

how I can solve this error?

Answer 1

try this

  $increment = 0;
  $max_width or $max_width=1;

  // Case 1:
  if ( $absolute_used == 0 && $percent_used == 0 ) {
    $increment = $width - $min_width;

    foreach (array_keys($columns) as $i) {
      $cellmap->set_column_width($i, $columns[$i]["min-width"] + $increment * ($columns[$i]["max-width"] / $max_width));
    }
    return;
  }

Your $max_width variable is either not assigned, or holds the value of zero. If that does not appear to be the case, try echo ing this variable's value inside your if statement.
