fwrite - Why output of this php program is not correct

Question

I'm trying to add prefixes and suffixes to some words. I did not write in the code, it is clear how the prefix and suffix are written, but my output is wrong. What is my code problem and how can I fix it? I will write my code and outputs below my php code :

<?php

$file = fopen("en-up.txt","r");
$afile = fopen("newa.txt","w");
$bfile = fopen("newb.txt","w");
$cfile = fopen("newc.txt","w");
while(! feof($file))
  {
$pishvandVApasvand = array("@@","@3210","@321","@32","@23",/* and a lot more */); 
$line = fgets($file);
    foreach ($pishvandVApasvand as $piv) {
        $a = "$piv$line";
        $b = "$line$piv";
        $c = "$piv$line$piv";

        fwrite($afile,$a);
        fwrite($bfile,$b);
        fwrite($cfile,$c);
      }
  
  }
fclose($file);
fclose($afile);
fclose($bfile);
fclose($cfile);

my input file is somthing like this :

Abandon
aBANDON
aBaNdOn
abandon
Ability
aBILITY
aBiLiTy
ability
Able
aBLE
aBlE
able
AbOuT

aBOVE

AbSeNt
Absent
aBSENT

Absorb
aBSORB
aBsOrB
absorb
AbStRaCt
... ( 9000 line )

and here is my output :

my question is Why newb file as Word + suffix is not ?
