.

$row['NO'] = '<a href="javascript:void(0)"        onClick="openmywindow(\''.$row['bcd'].'\',\''.$row['gfh'].'\',\''.$row['test2'].'\',\''.$_REQUEST['test1'].'\')">'.$row['abc'].'</a>'

In the above statement, what is the meaning of escaping the values in that manner such as ‘\’. How can i learn this?
In the above statement i want to replace the php variable $row['TEST2'] with a static value ‘OPEN’, but i am getting a syntax error.

    $row['NO'] = '<a href="javascript:void(0)" onClick="openmywindow(\''.$row['bcd'].'\',\''.$row['gfh'].'\',\'OPEN\',\''.$_REQUEST['test1'].'\')">'.$row['abc'].'</a>';

    Because the escaping is very confusing it might be better to use HEREDOC:

    $row['NO'] =<<<EOC;
<a href="javascript:void(0)" onClick="openmywindow('$row[bcd]','$row[gfh]','OPEN','$_REQUEST[test1].')">$row[abc]</a>
EOC;

    More about strings in the manual (including escaping and heredoc).

    PS: Do not use $_REQUEST. Instead use $_GET or $_POST (the one that is appropriate here.)
