EXplanation help

Posted on 16th Feb 2014 07:03 pm by admin

Hey all,

I am still fairly new to PHP programming and I am trying to put together a page where you select search terms from a drop down menu and it keeps the menu at your search choice in the menu after the search.

Here is the code I was suggested to use, but I am having problems understanding how it keeps the choice in the menu.

I can almost understand how it works, but I need a little push to grasp it.

Here is the code:

foreach($options as $key => $content)
{
if ($key == $value) $select = ' selected="selected"';
else $select = NULL;
$html .=
'<option value="' . htmlspecialchars($key) . '"' . $select .
'>' . htmlspecialchars($content) . '</option>' . "n";
}

Now I understand how to walk through the code, but I am having trouble understanding how it holds over the choice.

THanks in advance for the help...
