Handling $_FILES['name1'] with increment name

Question

my question:

<input type="text" name="sample1">
<input type="text" name="sample2">

this input add with javascript with limit 10 max = sample10.

how to handle this with php? like $_POST['sample$i'].

for ($i = 1; $i <= 10; $i++) {
}

and if it can be done, $some$i = $_POST['sample$i'].

can i insert to db with '$some1', '$some2'?

Better to just use `name="sample[]"` several times, no keys needed, then `$_POST['sample']` will be an array, much easier to deal with. — rjdown, May 22 '15 at 23:54

it's a lot easier to do it this way. In your form. set this up as:

<input type="text" name="sample[]" />

and then in your php use an array like so:

foreach $_POST['sample'] as $sample {
  echo $sample.'<br/>';

}

This way you don't have to be limited to a finite number of rows.

Yeah, you can use ${"some$i"} = $_POST["sample$i"]; but PLEASE, don't. Use an array to do the job.

Either use $_POST['sample'.$i] or use sample[] as name attribute & iterate over that.
