Question

Let s say file test.php looks like this:

<?php
echo  Hello world. ;
?>

I want to do something like this:

$test = include( test.php );

echo $test;

// Hello world.

Can anyone point me down the right path?

Edit:

My original goal was to pull PHP code intermingled with HTML out of a database and process it. Here s what I ended up doing:

// Go through all of the code, execute it, and incorporate the results into the content
while(preg_match( /<?php(.*?)?>/ims , $content->content, $phpCodeMatches) != 0) {
    // Start an output buffer and capture the results of the PHP code
    ob_start();
    eval($phpCodeMatches[1]);
    $output = ob_get_clean();

    // Incorporate the results into the content
    $content->content = str_replace($phpCodeMatches[0], $output, $content->content);
}

Answer 1

Using output buffering is the best bet.


ob_start();
include  test.php ;
$output = ob_get_clean();

PS: Remember that you can nest output buffers to your hearts content as well if needed.

Answer 2

test.php

<?php

return  Hello World ;

?>

<?php

$t = include( test.php );

echo $t;

?>

As long as the included file has a return statement it will work.

Answer 3

You can also have the included file return the output, rather than print it. Then you can grab it into a variable, just like you do in your second example.

<?php
    return  Hello world. ;
?>
