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.

Did you know?Explore Trending and Topic pages for more stories like this.
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...
