function remove_all_occurrences($s, $ch) { 
    $n = strlen($s); 
    $total = 0; 
    for ($i = $j = 0; $i < $n; $i++) { 
        if ($s[$i] != $ch) {
            $s[$j++] = $s[$i]; 
        }
        else {
            $total++; 
        }
    } 
    while($total--) {  
        $s[$j++] = " "; 
    } 
    return $s; 
} 
   
  
$s = "php programming version 7.3.1";
  
$s = remove_all_occurrences($s, 'p'); 
  
echo $s;
  
  
   
/*
