Array problem

I am trying to fill arrays to use in my javascript codes as following

[code=php]
var codes = new Array (
<?php $sql1 = mysql_query(“SELECT * FROM produse order by cod ASC”) or die(mysql_error());

while($row1 = mysql_fetch_array($sql1))
{
echo ”’.$row1[“cod”].”,’;
}
?>’murat_’)

var clients = new Array (
<?php $sql2 = mysql_query(“SELECT * FROM magazalar order by shop_name ASC”) or die(mysql_error());

while($row2 = mysql_fetch_array($sql2))
{
echo ”’.$row2[“shop_name”].”,’;
}
?>’murat’)[/code]

This process doesnt return any results
But when i erase one of the arrays above, the other one works perfectly or in the second array when i intentionally change the part like

[code=php]while($row = mysql_fetch_array($sql2))[/code]

here i am intentionally write false code ($row instead of $row2)

Then i get the list for the 1st one as it is supposed to be

So what can be the error i am making here?

Also in #JavaScript _↴
