[OpenLayers-Users] How many layers can I use with "OpenLayers.Control.WMSGetFeatureInfo"

[Karina Guardado]

I forgot to ask if it s better to use select from text file where I have
one php application and when just click on one point I get the information
but the issue is that I can not change the popup style with css, because it
uses a print option with a tab separation and I
need to show a table with css style but have not idea how to do it here is
the code of my file.

 var  infecos = new OpenLayers.Layer.Text( \"infecos\", {location:
\"textsedesecos.php\"},
             \"http://myhost/cgi-bin/mapserv?MAP=/myfolder/mymapfile.map\");


this the textsedesecos.php file
<?php
    $host = "myhost";
       $user = "myuser";
        $pass = "mypass";
        $db = "mydb";


        // open a connection to the database server
         $connection = pg_connect ("host=$host dbname=$db user=$user
password=$pass");
        if (!$connection)
        {
            die("Could not open connection to database server");
        }


 $querystring="select name, descr, muni, codmuni, dpto, x(the_geom) as x,
y(the_geom) as y from ucsf_final2";


$res = pg_query($connection, $querystring);



 print("point" . "\t" . "title" . "\t" . "description" . "\t" . "iconSize"
. "\t" . "icon". "\n");

while ($thisrec = pg_fetch_array($res)) {

   $x = $thisrec['x'];

   $y = $thisrec['y'];
   $name = $thisrec['name'];

    $descr = $thisrec['descr'];

   $muni = $thisrec['muni'];
   $codmuni = $thisrec['codmuni'];
   $dpto = $thisrec['dpto'];




   print("$y,$x" . "\t" . "Nombre: $name" . "\t" .
"Descripción:$descr<br>Municipio:$muni<br>Codigo:$codmuni<br>Departamento:$dpto"
. "\t" . "14,14" . "\t" . "htt://myhost/ecos_blue24.png" .  "\n");
   }
