PHP reading from txtfile?

[Anon]

Hello there,

I have a question and I REALLYREALLYREALLY hope someone can help me out..
I have a file called questions.txt for instance, which is read by
another application. But I want to make it easy to edit (for people
who don't have FTP access).
Say for instance that I've got in there something like 'questions=20'.
(to make a for-loop with 20 edit boxes).
Then I want some variable in the PHPfile set to that specific variable
from questions.txt.
How do I do this?

Hope someone can please help me.

Thanks,
-Jordi

Easiest way is to create a file with a line like this:

$questions=20;

then just include it. But I'm not sure if that's the answer to your question.

No what I meant is that I have a .txt file...
On the first line of that textfile there is, for instance, a line
questions=20
I want php to somehow set a variable to that x after the
= part.. So if I change 20 to 25 in the textfile and run the
phpfile, the variable $value will be set to that 25 which is
set in the textfile..

Hope someone can help me...

I had to do something similar for a random quote/tagline file...

You're parsing a number out of text... the cheeze generic way to do this would be have the number on it's own line, and then...

$fn="yourfile.txt
if (!file_exists (".\$fn")) {
echo ("PHP4.FileNotFound.$fn");
} else {
$fcontents = file ('.\$fn');
$lines= $fcontents[0];
settype($lines, "integer");
}

Take a file. Make sure it's there. If it isn't; notify, if it is, get line 0, (first line) dump the number into a varible, and make the varible a "number".

Not too bad for 2:33am, eh?

Hey there =)
Good day. It's 4:16AM in the heartland. =)

Thanks for your help.. I've got a short question..
is it possible to make a variable IN a variable?
Something like:

for($counter = 1; $counter <=10; $counter++)
{
$data$counter=$data;
}

is that possible?

I get the feeling that is a direct catalysm and would cause php to explode.

Are you trying to do a reference? (Like, $robert is the same as $bob; as in a "alias" or "link".) Or are you trying to include one in the other... such would be...

$Robert = &$bob <-- alias

$Robert .= $bob <--- Similar to $robert = $robert + $bob in qbasic.
