How can I store a variable from an HTML from into a text document and how can i read the variable back into php from the text document?

Is there any structure to the variables? Do I have to declare them?

Can I alter the variables from one type to the other? (ie is there something like text1.text:=IntToStr(Number1*Number2); )

My host doesn't support MySQL and I was going to write a php shout box (I think I should be able to do that). I have a feeling that you could post PHP into the shoutbox so that it stores the php in the text document. When it comes to retrieve the text and the php it would parse it as part of my site? For example could someone post an infinate while loop and hang the browser? Could that happen and could I stop it?

Any books you would recommend also?

I set up an Apache server just so I could practise PHP and I love it Smile

If you have MS Access, I think PHP can read/write to an MDB file which will make it easier on you. You have to consider the worst case scenario which is 2 people trying to post at the same time and you get a file I/O collision.

I believe to get variables from a POST form, you access the variable's data via:

$_POST['name']

where name is the name of the HTML form object like a text box.

Go to www.php.net and find your way to the documentation download section. You can download the PHP docs in many formats (PDF, HTML tarball, CHM) and look up the routines you want to use. Like if you need to convert a binary number into its string representation there's a rountine for that.

And if someone wants to get cleaver and put PHP code in their post, you could do some validation on the post to make sure they're posting just text and not PHP or Javascript. As far as PHP code goes, I don't think you'll have to worry because it'll just output it as text to the user and they'll see the code in their web browser, but the PHP parser on the server side just prints out the text and moves on with execution in this particular script. The only way to throw it off track from execution in the current script is either by #include directives or calling an external routine (also included via #include).

There was about 70 on it, but I kept deleting it. I removed the Proceed button but it must have still been stored on peoples comps so I was still getting them :S

This is how I wrote and read from a text file if anyone is interested.

To read

Code: Select all




$filename = "file.txt";





$list = file_get_contents($filename);

To write

Code: Select all




$two = $_POST['sname'];


$one = $_POST['wank'];


$space = " wanks for ";


$after = " per week, ";


$combined = "";


$combined .= $two;


$combined .= $space;


$combined .= $one;


$combined .= $after;


$combined .= $list;





$fp = fopen("wank.txt", "w");





fputs ($fp, $combined);





fclose($fp);
