array.php - Array Functions

In regard to the array.php assignment page, the instructions state "Using array functions echo back to the user the selections he/she made.", what are these functions supposed to do? Should we use the functions listed on page 104-106 to alter the information sent by the user or just output the created array using a for loop or the print_r function? Also, if we do need to use the above mentioned functions how many do we need to use?

Say you have tw check boxes like this:

Language: PHP
<form action="">
<input type="checkbox" name="vehicle" value="Bike">I have a bike<br>
<input type="checkbox" name="vehicle" value="Car">I have a car 
</form>

You need to send "vehicle" as an array, then extract it and present the selections back to the user. How you do that is your choice.

Awesome! Thanks Mac! I thought I did it wrong...

I know how to read data from an input element on a form and use it as a variable in php.
But if I have say an extra textbox that I want to use to display my results, hoW do I get the
results to diSplay on the text box? this all on one php file !

yOU URGENT RESPONSE WILL BE APPRECIATED!

@ Mbux

Try the following:

Language: PHP
<input type="text" name="some_textbox" value="<?php echo $value_to_output; ?>" />

The value of your textbox is the variable that holds the data.
