PHP Question. -- Text.

aingaran · #1 04-02-2003, 06:25 PM

Hi everyone,

I was wondering if it's possible to do this.

Some value is returned in text format after performing something.

Example, a text file is returned containing just this.
(without the ---)
------------------------------------
THE_ANSWER=10
------------------------------------

From that text file, (using some other script obviously)
Is it possible to do this?

PHP Code:


			
if ($the_answer=="10")

{

do this

}

else

{do something else.

}

So, in essence, making 'THE_ANSWER' into a variable from the text file.

It doesn't have to be a text FILE.
It can be just text that is returned, in the browser. (file not created, text just diplayed)

I hope you understand my gibberish

Thanks,

Just wrote and tested the program. Works good. This code will work only with the first line of the file.

PHP Code:


			
<?php



    

    error_reporting (0);

 

 /* the file we will open */



     $file = 'file.txt';

    

 /* read the file into the array $content */



     $content = file ($file);





    

/* split the first line of the file to THE_ANSWER and 10 */

    

    $line = split ('=', $content[0]);





/* delete spaces */    

    

    while (list($key, $value)=each($line))

        $line[$key] = trim ($value);



    

/*  

    Make_THE ANSWER as a variable 

    using the Variable variables feature 

    in PHP and assign it the value that 

    comes after equal symbol in file 

*/



     $$line[0] = $line[1];



    echo $THE_ANSWER;





?>

null's has the advantage that he tested it. mine is off the top of my head, but, should it prove feasible, has the advantage of being briefer.

Just slap a "var $" onto the front and eval it. Oh yeah, with a semi-colon on the end and quotes around it.

truthfully null's might be a better idea. in either case, you get to work with concepts such as a "variable variable" as he mentioned, or, in my case, eval().

Thank you sooo much!!

Another question.

The script is for a file..

Is it possible to do the samething with content returned INTO broswer, instead of a text file?

Thanks,

umm, you mean form?

PHP Code:


			
<html>

<body>

<form method="get" action="/nextpage.php">

<input type="text" name="words">

<input type="submit">

</form>

</body>

</html>

/nextpage.php

PHP Code:


			
<?php

echo $words ;

?>

if thats what you mean...

aingaran · #6 04-02-2003, 08:50 PM

well, from nextpage.php

whatever is echo'd. It'll be in a text form.

I'd like to changed the echo'd text into a variable.

page.php
<?

echo "Answer = 1";

?>

Now, from page.php

I'd like to do the following:
change 'Answer' into $answer so that I can do this:

if ($answer=="1")
{do something}
else
{do something else}

Here you go:

page.php

PHP Code:


			


<?



// I removed "Answer = " because it makes it easier to process



echo '1';



?>

processresult.php

PHP Code:


			


<?php



$url = 'http://www.yourwebsiteaddress.com/pagewithvariable.php';



$answer = file($url);



if ($answer[0] == '1') {

    echo 'Variable equaled one';

}

else {

    echo 'Variable did not equal one';

}



?>

I am assuming that you will have page.php on one server and processresult.php on another as it would be the only reason to do it this way.

Also the example above is only set to accept one variable; the single variable must also be on the first line for this to work.

Now that I reread null's post and looked at mine, there really isn't much difference.

Sorry null if it looks like I was copying your post.

aingaran, the "file" function can load local or remote files.

no problem, it's open source

Guys,

I couldn't thank you enough for your efforts.

But, I haven't explained the scenario properly.

A file will not be created.

I just used the file as an example.

I have a script..Which would do something on another server.
The other server will return some sort of response in text form. (a file will not be created.)

I'd like to take the response from the other server, and convert some of it into variables.

Thanks,

I believe that the solution to your problem can be solved by utilizing the code that I provided above. It allows for the scenario you are speaking of.
