<INPUT TYPE="checkbox" NAME="checkbox[]" VALUE="2">2<br>
<INPUT TYPE="checkbox" NAME="checkbox[]" VALUE="3">3<br>
<INPUT TYPE="checkbox" NAME="checkbox[]" VALUE="4">4<br>
</TD>
</P>
<P>
<INPUT TYPE="submit" NAME="delete" VALUE="Delete">
</P>

2. can I do it? and how?
3. which global variable keeps the values of this array?

An array is definately the way to go. There are a few different ways to grab the values dynamically. What are you going to do with those values? Update/insert into a database? search a database? echo them?

i will use it for all kind SQL queries on a data base

Here's an example of deleting all the records that were checked. If you have an older version of PHP, change $POST to $HTTP_POST_VARS

$query = mysql_query("DELETE FROM your_table WHERE id IN VALUES('" . implode("','", $_POST['checkbox']) . "')") or die(mysql_error();

but how must i call the checkbox in the html code, because when i run the script this appears

Warning: Bad arguments to implode() in /var/www/html/deleteip/delete_ip.php on line 35

and i am using postgres

[cgraz]

I've never used postgres, but if you want the values, then use a foreach loop and do a seperate query for each one

foreach($_POST['checkbox'] AS $value) {
   echo $value . "<br>";
}

That will simply echo each of the values so you can see how it works (if you're not familiar with a foreach loop), but you can modify it to execute a query each time.
