PHP-code in a variable

[Anon]

Hi,

I was wondering how the following is done. I've got a main page (php) where I include a .txt file. In this .txt file two variables are defined ($title and $content). In the main page the title and the content are displayed. I now want a part of the $content to be a piece of php-code which contains new variables and functions. So now my question is how do I put this php-code into the $content and thus define new variables and functions inside this variable? Any suggestions would be very much appriciated.

Thanx Michiel

include() and require() already do that.

just put whatever PHP code you want into the included files and it will be parsed automatically.

But I mean the following:

In the main page I include data.txt. data.txt looks like this:

<php?
$title = "Title of this category";
$content = "Text for this category";
?>

In the main-page I use these 2 variables and I display them. Now I would like to add a piece of php-script in the content (the random text script from yesterday). I'd like to know whether I can put this script inside the $category in the data.txt? So is the following valid?

<php?
$title = "Title of this category";
$content = "Text for this category

//put the text into an array
$text_array = explode ("*******", $your_text_file);

//randomize the array
shuffle ($text_array);

//display one of them
echo "$text_array";

// if you want to display all of them randomly
for($arrayLoop=0;$arrayLoop <= count($text_array);$arrayLoop++){
echo "$text_array[$arrayLoop]";
}
";
?>

Here I've just put the script inside the $content in the data.txt.

Thanx, Michiel

$content would trigger a parse error since the dbl-quote in explode would terminate the string. You would need to escape all of them...see addslashes().

If wanted to turn that into live PHP code/variables, you'd use the eval() function. Of course you'd get a parse error since the first line isn't vaild.

Why do you want to put the script into a string?

If you want to put some extra data into the $content var, then that is what you should do:

<php?
$title = "Title of this category";
$content = "Text for this category ";

//put the text into an array
$text_array = explode ("*******", $your_text_file);

//randomize the array
shuffle ($text_array);

// Adding to the content var here:
//
//display one of them
$content .= "$text_array";

// if you want to display all of them randomly
for($arrayLoop=0;$arrayLoop <= count($text_array);$arrayLoop++){

// Adding to the content var here:
//
$content .= "$text_array[$arrayLoop]";
}
";

// now $content contains everything.
?>
