Eval problem

clcope

I have a file that contains the code below. My script reads the file and then puts it into a variable...

<br><br>
<?php
$SESSION['file'] = $SERVER['SCRIPT_FILENAME'];
$_SESSION['strip_images'] = "No";
echo "Today is: " . date("l dS of F Y h:i:s A");
?>
<br><br>
This is the last line to print.

Now I want to execute the code and echo the results. So I remove the <?php and ?>. Then I echo the results and I get nothing.

Here's the code
$PHPrint = str_replace( "<?php", "", $PHPrint );
$PHPrint = str_replace( "?>", "", $PHPrint );
$PHPrint = stripslashes("$PHPrint");
eval("\$PHPrint = \"$PHPrint\";");
echo $PHPrint;

Any ideas what I am missing?

don't use eval(). why not simply [man]include[/man] the file? if you want to capture the output as a string then you can always use the Output Control Functions.

I can't include it as this is a script to create a printer friendly page, so the contents of the variable will be different each time.

Any other ideas?

why would that prevent you from using [man]include[/man]?

This code is on the page that needs to become a printable page. There is a link on there to the script that reads this file to produce the printable page.

For example, article1.php is an article that has some php code to display the date or any other php task. There is a link on this page to another file for creating a printable page. The script takes the referring page and opens the file and displays the contents between a start/end point. Most of the time, there is just text between the points...however, we ran into an issue where there is php code between them, so we have to tweak the script to execute any php code that may be between the start/end points.

I hope this makes sense.

Or use CSS when laying out your pages, so that the difference between a screen-friendly page and a printer-friendly page can be just a matter of using a different stylesheet.
