Whether such two statements can be combined into one sentence.
$get _rows = mysql_num_rows ("Select ID from News where class_type= ' category '");

if ($get _rows) {
$get _list=mysql_fetch_array ("SELECT * from news where class_type= ' category '");
....... Loop display
}

------to solve the idea----------------------
Unfortunately, instead of being merged into one sentence, I would like to divide it into three sentences.
$rs = mysql_query ("Select ID from News where class_type= ' category '");
if ($get _rows = mysql_num_rows ($rs)) {
$get _list = mysql_fetch_array ($RS);
....... Loop display
}

------to solve the idea----------------------

$rs = mysql_query ("Select ID from News where class_type= ' category '");

$get _list = Array ();

while ($row = Mysql_fetch_array ($rs)) {
Array_push ($get _list, $row [' id ']);
}
$get _rows = count ($get _list);
