Hey try this::

<?
$j=0;
for ($i=0; $i<=5; $i++){
$j++;
echo '<input id="'.$j.'" name="1" type="checkbox" value="" />';
}
?>

Variables inside single quotes will not be evaluated, which is why you need to concatinate. Alternatively, you can also use echo "<input id=\"$j\" name=\"1\" type=\"checkbox\" value=\"\" />";

echo ' <input id="<?php echo $j; ?>" name="1" type="checkbox" value="" />

You are already in a PHP code block, so you shouldn't be trying to open another code block within it...

echo ' <input id="chk'.$j.'" name="chk1" type="checkbox" value="" />

Also, I've added a prefix of 'chk' to your ID and NAME attributes since these must start with a letter (Use any letter - HTML standard).

Thank you very very much! you are perfect! Penders...if id not start with a letter where is the problem? just for html standard?

...if id not start with a letter where is the problem? just for html standard?

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

Yes, HTML standard. But if you don't follow the standards then it might not work in all/future browsers. There is usually a reason for the standards, they are not intended to make things harder. It could also be a problem with PHP. If

register_globals

is set then PHP will create a variable that matches your NAME attribute. PHP cannot have variables that start with a number either.
