Question

I am using HTML inside PHP like this.

for($i=0;$i<count($arrSql);$i++)
     $opt.="<option". if($_GET['pId'] == $arrSql[$i][0]){ echo "Selected";} ."value=".$arrSql[$i][0].">".$arrSql[$i][1]."</option>";

I have tested it for a long time and it looks correct, but it is showing an error and I don’t know where the bug is.

You can’t use concatenation and if together. Change it to:

for ($i=0;$i<count($arrSql);$i++) {
     $opt .= "<option"
        . ($_GET['pId'] == $arrSql[$i][0] ? " selected" : '')
        ."value=".$arrSql[$i][0].">".$arrSql[$i][1]."</option>";
