I've got a 2D array of movies with keys which was generated via phpMyAdmin via a MySQL Db.
(Plot cut off from copy pasting)
$films = array(
array('title' => 'Batman Begins','yr' => '2005','genre' => 'Action, Adventure','plot' => 'After training with his mentor, Batman begins his w...')
array('title' => 'Ted 2','yr' => '2015','genre' => 'Comedy','plot' => 'Newlywed couple Ted and Tami-Lynn want to have a baby, but in order to...')
array('title' => 'Ted','yr' => '2012','genre' => 'Comedy, Fantasy','plot' => 'As the result of a childhood wish, John Bennett\'s teddy bear, ...')
array('title' => 'Interstellar','yr' => '2014','genre' => 'Adventure, Sci-Fi','plot' => 'A team of explorers travel through a wormhole in spa...')
);
I've also got a foreach loop, to loop through the 2D array and return the results as a table:
$out = "";
$out .= "<table>";
foreach($films as $key => $element){
$out .= "<tr>";
foreach($element as $subk => $subel){
$out .= "<td>$subel</td>";
}
$out .= "</tr>";
}
$out .="<table>";
echo $out;
And from the results I see on the web page, this displays it like this:
Batman Begins 2005 Action, Adventure After training ...
How would I be able to display the key as the column header? I've tried making another foreach loop inside the main one, but that returned the header like this: titleyrgenreplottitleyrgenreplot
etc.
How would I be able to properly format it in a table, so headers appear?
Also just a small, quick question: instead of exporting the database from phpMyAdmin as a PHP array, how would I be able to update the PHP/webpage when a change has been made in the MySQL database table?

For displaying fields as header we just have to loop through the keys of 1st sub array and add another row(<tr>
) with table header(<th>
) before loop through the entire result. Generally we display headers only once.
$out = "";
$out .= "<table>";
$out .= "<tr>";
foreach($films[0] as $key => $value)
{
$out .= "<th>".$key."</th>";
}
$out .= "</tr>";
foreach($films as $key => $element){
$out .= "<tr>";
foreach($element as $subk => $subel){
$out .= "<td>$subel</td>";
}
$out .= "</tr>";
}
$out .="<table>";
echo $out;

here is how you will get your headers:
$headers="<thead><tr>";
foreach($films as $key => $element){
$headers.= "<th>$key</th>";
}
$headers.= "</tr></thead>";
So your code should now look like:
$out = "";
$out .= "<tbody>";
$headers="<table><thead><tr>";
foreach($films as $key => $element){
$headers.= "<th>$key</th>";
$out .= "<tr>";
foreach($element as $subk => $subel){
$out .= "<td>$subel</td>";
}
$out .= "</tr>";
}
$out .="</tbody><table>";
$headers.= "</tr></thead>";
echo $headers;
echo $out;
