Being Echoed

HTML Echoed Out
Does anyone have any idea why when I echo HTML it doesn't parse the HTML but outputs the code? I even added two <h2> tags manually and it works, so it's just from pulling it out of the database.

PHP Code:

<?php
//The <h2>s work fine but the array variable being outputted doesn't parse the HTML
echo "<h2>".$profile['biography']."</h2>";
?>

HTML Echoed
I have the notion that everything is more secure if everything is in php, and nothing is in html. Perhaps I am mistaken in my understanding. But, because I believe that everything would be more secure in php, I am trying to take an html form, and find a way to ECHO it in php.

It is an example form that I found in google.  It works just fine as HTML, and it is a submit to a php script which will receive the data through $POST. But, I am trying to build all the HTML in $form and then echo it. I am not having much success. Code:

Echoed The MySQL Query
I'm currently building a time booking system, and what I have done is created a few tables in my database and populated these with some test data.

The problem I'm having is that I know for a fact that when I click on the 1st Sept for example the first couple of time slots have been taken,so for a test I've used the word 'booked', this works, if the time slot is not taken then it should say 'available', this doesn't do it.

I have echoed the MySQL query and I've test this on the MySQL console and it works, but yet it says 'booked' when its really not.

Saving Result Of Function Without Being Echoed
I am trying to save the function "rand(1, 1000000)" in a variable but when I am for example trying:

$randomnumber = rand(1, 1000000);

it is executing it right ahead while when i try

$randomnumber = "rand(1, 1000000)";

or

$randomnumber = 'rand(1, 1000000)'

It is saving rand(1, 1000000) as variable.

But what I need is a variable saving the result of rand(1, 1000000) so the number does not change either.

Any ideas how I would do this?

Accessing Session In A Php Page Echoed By Fstream
if I load a php page from controller.php like this:

$handle = fopen("http://localhost/MvCphp_1.0/View/maincatgory.php", "rb");

Get A Database Stored Date Echoed On A Website
I'm trying to get a database stored date echoed on a website. The problem is it won't show up. This is the code piece getting the rows:

$row3 = mysql_fetch_array($result);

This is the piece declaring date to $actualdate:

$actualdate = $row3['date'];

This is the piece echoing the date:

echo $actualdate;

I'm sure I'm doing some damn mistake here, it's probably really easy for you other guys to solve.

How To Create A Hidden Field Variable From An Echoed PHP Figure?
I have a PHP script on a shopping cart summary page that creates an invoice number and then echoes it to the page. This page, when submitted, will go to the shopping cart processor.

The echo portion of the script is working properly, it generates the number as intended.

My problem is that, not being very experienced in PHP, I want the invoice number not only echoed (which it is doing properly now), but also to populate a value in a hidden field that is submitted to the shopping cart processing page. My question is how do I populate the hidden field with the figure that is now being echoed in the script below?

The script that generates and echoes the invoice number is as follows:

<?php
echo "SA"; //department code
echo date ("mdy"); //date generator
// begin counter this reads figure from "count_file.txt"
if (file_exists('count_file.txt'))
{
$fil = fopen('count_file.txt', r);
$dat = fread($fil, filesize('count_file.txt'));
echo $dat+1;
fclose($fil);
$fil = fopen('count_file.txt', w);
fwrite($fil, $dat+1);
}
else
{
$fil = fopen('count_file.txt', w);
fwrite($fil, 1);
echo &#391;'
fclose($fil);
}
// end counter
?>

The hidden field is as follows:

<input name="Invoice_Num" type="hidden" id="Invoice_Num" value=" ">

I would like the value in the above to reflect the invoice number that is echoed by the above PHP script.
