Just name each series like this. You pick them up like this:

$_POST etc.

This will contain the array.

BTW place quotes around your name attribute values (name="txtName[]"), otherwise you fail xhtml validation.

OK. Note my point about quotes around the attribute value.
Say you have this sort of thing going on:

<td><input type="text" name="txtName[]"/></td>
<td><input type="text" name="txtMaths[]" /></td>
<td><input type="text" name="txtScience[]" /></td>
<td><input type="text" name="txtEnglish[]" /></td>

<td><input type="text" name="txtName[]"/></td>
<td><input type="text" name="txtMaths[]" /></td>
<td><input type="text" name="txtScience[]" /></td>
<td><input type="text" name="txtEnglish[]" /></td>

<td><input type="text" name="txtName[]"/></td>
<td><input type="text" name="txtMaths[]" /></td>
<td><input type="text" name="txtScience[]" /></td>
<td><input type="text" name="txtEnglish[]" /></td>

I assume from this you're placing a student's name in txtName with grades or marks in the others.

You can have as many of these inputs as you like in the form, but perhaps use and 'add more rows' or 'delete this row' javascript functionality to avoid having loads of empty rows. Even if the textbox is empty, the resulting post array will have a value for it (=""). However, back to the problem:

Each "record" (a student's name and grades) will be given a unique position within each of the four post arrays. Remember that they always start with position '0', unless coded otherwise.

//these are all arrays!
$name = $_POST['txtName'];
$maths = $_POST['txtMaths'];
$sci = $_POST['txtScience'];
$eng = $_POST['txtEnglish'];

$i = 0;
while($i < count($name)){
  if(trim($name[$i]) != ""){
     ... clean the data...
     $rs = mysql_query("INSERT INTO mytable SET student='{$name[$i]}', maths='{$maths[$i]}',science='{$sci[$i]}',english='{$eng[$i]}'");
     ... check the data has been added...
     $i = $i + 1;
  }
}

As well as inserting new records you could as easily use UPDATE - however for this you'd use the student id to filter the recordset.

Recap:

student #1
name = $name[0]
maths grade = $maths[0]
science grade = $sci[0]
English grade = $eng[0]

student #2
name = $name[1]
maths grade = $maths[1]
science grade = $sci[1]
English grade = $eng[1]

ETC, ETC.
