Variables

[Anon]

Dear all ,

See following code :

<form name="whatever" action ="test.php" METHOD="Post">
<input type='text' name='row1'><BR>
<input type='text' name='row2'><BR>
<INPUT TYPE="Submit" VALUE="Submit" >
</form>

this is test.php
<?php echo $row1;
echo $row2; ?>

Suppose I have 1000 rows than the test.php would be :

echo $row1;
....
echo $row1000;

Can I make a lus like :

for ($i=1; i<=1000; $i++) {
echo $row$i;
}
This is not working but I wonder if there is a solution for this???

THX for the Help

What you are looking for are called "variable variables". The trick is to treat the actual name of the variable as a string and enclose it in braces ({ and }). Like so:

for ($i = 1; $i <= 1000; $i++) {
echo ${"row".$i};
}

and that should work. Hope that helps!

One trick you can use is to name your variables as an array.

<form name="whatever" action ="test.php" METHOD="Post">
<input type='text' name='row[]'><BR>
<input type='text' name='row[]'><BR>
<INPUT TYPE="Submit" VALUE="Submit" >
</form>
*NOTE: you don't have to put the index in the array brackets

Then in your PHP Script you'd have an array called $row. You can access $row[0] or $row[1000] or whatever you like.
