How to compile php code at runtime?

Hi, What I mean by the question is if i have some thing like

$script = "<? echo \"\nHello World!\"; ?>"
// I Want to compile the above string here or just include it here 

PHP:

 

hmm, can you be more specific? but basing on your sample it seemed that you just want to run a php line, then the above code will work, assuming you have php setup with your webserver(usually apache)

 

What I want to do now is to include the code that '$script' has into a function .... what i am trying to do is a template substitution , that is there are some variables that come at runtime to a function and that function has a predefined string. Function just has to substitute the arguments (array with keys and values) and return whatever was evaluated by that 'script' string .. am I clear??

 

function doSomething($func) {
echo "Hello ";
eval($func);
}

$func = "echo 'World!';";
doSometing($func);

like that?

 

a more elaborate example:

function subst ($list) {
 $script = "$feed = \"\"; 
                  foreach ($list as $user) {
                       $feed +="\nHello $user!\";
                  }";
 //include the $script here and use $list to substitute
 //one simple thing i can do is to write $script to some file and include that file
 //i will get some output to $feed  and that is what i want  
}

exactly!! Thanx Mr. Kwaku!! I was a fool not to think of 'eval', because it is availble in python and i was using python too ...
