Having an issue with eval'd code

TlcAndres · 12-17-2007, 01:30 AM

Well this is the file thats being parsed

PHP Code:


			
<a href="<[siteurl]>"> Hello </a>

<phpcode>

if(true)

{

    echo('ello there');

}

</phpcode>

and this is the file that runs the code within <phpcode>

PHP Code:


			
        //runs the php within template files             

        public function Runphp($txt)

        {    

            //split it away from the rest of the text

            $php = preg_split("/(<phpcode>.*<\\/phpcode>)/Us", $txt, -1, PREG_SPLIT_DELIM_CAPTURE);

            $stop = count($php);

            

            //run the loop and execute the php

            for($phpe = 0; $phpe < $stop; ++$phpe)

            {

                $phpexc = $php[$phpe];

                if (preg_match("/^<phpcode>(.*)<\\/phpcode>/Us", $phpexc, $phpexec))

                {

                    $phpex_p = $phpexec[1];

                    ob_start();

                    eval($phpex_p);

                    $c =  ob_get_clean;

                    $c = str_replace('ob_get_clean','',$c);

                    $c = preg_replace('/(<phpcode>.*<\\/phpcode>)/Us',$c,$txt,$stop);

                    return $c; //return it

                }

            }

        }

maybe I'm missing something plainly obvious but the hello link is supposed to be before the 'ello there' and it's being switched around, any help would be appreciated

(sorry if it's in the wrong section)

I kinda refixed the script, using PHP 5.2.5.
Execute.php;

PHP Code:


			
<a href="<[siteurl]>"> Hello </a>
<phpcode>
if(true)
{
    echo 'First off, why would you use echo ()? It\'s a function more simply used as echo "this";, not like you had.<br>';
    echo 'next off, tryping if (TRUE) { on one line, not on two, will shorten the length of your script thus the load time.';
}
</phpcode>

File.php;

PHP Code:


			
<?php
        
        //runs the php within template files             
        function Runphp($txt)
        {    
            //split it away from the rest of the text
            $php = preg_split("/(<phpcode>.*<\\/phpcode>)/Us", $txt, -1, PREG_SPLIT_DELIM_CAPTURE);
            $stop = count($php);
            
            //run the loop and execute the php
            for($phpe = 0; $phpe < $stop; ++$phpe)
            {
                $phpexc = $php[$phpe];
                if (preg_match("/^<phpcode>(.*)<\\/phpcode>/Us", $phpexc, $phpexec))
                {
                    $phpex_p = $phpexec[1];
                    ob_start();
                    eval($phpex_p);
                    $c =  ob_get_clean;
                    $c = str_replace('ob_get_clean','',$c);
                    $c = preg_replace('/(<phpcode>.*<\\/phpcode>)/Us',$c,$txt,$stop);
                    return $c; //return it
                }
            }
        }  

        $file = file_get_contents('execute.php');
        
        Runphp($file);
        
?>

Exports:

PHP Code:


			
First off, why would you use echo ()? It's a function more simply used as echo "this";, not like you had.
next off, tryping if (TRUE) { on one line, not on two, will shorten the length of your script thus the load time.

tryping if (TRUE) { on one line, not on two, will shorten the length of your script thus the load time.

I would never give up usability for 0.000000000000000001 ms of faster loading time.

Hey, don't shoot the messenger. I simply read it somewhere and I picked it up. Next to that, why would you create one extra line at each if, else or elseif line? I guess the same goes for while, for and foreach? Your scriptsize will get smaller which is better.

Getting back to the real topic subject, let me know if it works out.

the problem is not the running of the script it's how it presents the data

PHP Code:


			
<a href="<[siteurl]>"> Hello </a>
<phpcode>
if(true)
{
    echo('ello there');
}
</phpcode>

it's supposed to be presented like so

PHP Code:


			
Hello ello there

instead it's being presented as

PHP Code:


			
ello there Hello
