HTML dynamic number of elements in a form with post - php

Question

I have code that basically uploads a spreadsheet of data, could have 5 columns or 10 columns or whatever. Each column needs to have a drop down box specifying the data type, and the data types selected should be submitted via post with a form to another php site. How would I do this, this is the code that creates the elements.Is there a way to dynamically create elements, like delimist . attCount, and how would i put this loop into an html form to submit the data? Is there any way to put the values of all of these into an array for convince? Thanks.
EDIT: Ok thanks for the dynamic stuff, but how would i put this into a form and submit this via post to another page. Or is there another way to post information. I dont know much about php.
while($attCount < count($attArray)) {
echo "<select name=\"delimList\">";
echo "<option value=1>tab</option>";
echo "<option value=2>comma</option>";
echo "<option value=3>semi-colon</option>";
echo "<option value=4>ampersand</option>";
echo "<option value=5>pipe</option>";
echo "</select>";
$attCount = $attCount + 1;
}

Answer 1

Using a foreach loop and assigning the first index in your array will give you what you're expecting:
$options = [1=>'tab','comma','semi-colon','amperstand','pipe','another-value'];
echo "<select name=\"delimList[]\">\r\n";
foreach($options as $val => $option){
echo "<option value=\"$val\">$option</option>\r\n";
}
echo "</select>\r\n";
output:
<select name="delimList[]">
<option value="1">tab</option>
<option value="2">comma</option>
<option value="3">semi-colon</option>
<option value="4">amperstand</option>
<option value="5">pipe</option>
<option value="6">another-value</option>
</select>
To sumbit the page you'll need to put everything inside of
<form method="post"> // you may want to add an action="..."
.... // if you want to post to another page,
</form> // instead of the same one
You'll also need a submit button too...
<input type="submit" name="submit" value="submit" />
After submit you can check the values like this:
if(isset($_POST['delimList'])){
foreach($_POST['delimList'] as $key => $value){
echo "delimList[$key] = $value";
}
}

You can put all the value of all of these into an array… by putting all the values of these into an array!
$myArray = ['tab','comma','semi-colon','amperstand','pipe','another-value'];
echo '<select name="delimList">';
for ($i = 0; $i < count($myArray); $i++) {//Loop thru all
echo '<option value="'.$i.'">'.$myArray[$i].'</option>';
}
echo "</select>";
