There may be simpler solutions but give this a shot :
$y=0
while(( ($contents=fread( $handle, 100 )) != '' )) {
//$A etc. should be set to 0 at the beginning of while loop.
$A=0;
$G=0;
$C=0;
$T=0;
for ($i=0; $i<100; $i++)
{if($contents[$i] == 'A' )
{
$A++;
}
else
if($contents[$i] == 'G' )
{
$G++
}
etc...
}
//picture is drawn at the end of for loop but inside while loop.
$imageyel = imagecreate($A,10);
$imageblu = imagecreate($G,10);
$imagegre = imagecreate($C,10);
$imagered = imagecreate($T,10);
$back = ImageColorAllocate($imageyel,255,255,255);
ImageFilledRectangle($imageyel,$y,0,110,$y+10,$back);
$yel = ImageColorAllocate($imageyel,255,255,0);
ImageFilledRectangle($imageyel,1,$y+1,1+$A,$y+10,$yel);
$red = ImageColorAllocate($image,255,0,0);
ImageFilledRectangle($imagered,1+$A,$y+1,1+$A+$G,$y+10,$red);
$green = ImageColorAllocate($image,0,255,0);
ImageFilledRectangle($imagegre,1+$A+$G,$y+1,1+$A+$G+$C,$y+10,$green);
$blue = ImageColorAllocate($image,0,0,255);
ImageFilledRectangle($imageblu,1+$A+$G+$C,$y+1,1+$A+$G+$C+$T,$y+10,$blue);
$y=$y+10;
