Easy: $html = file_get_conten ts('http://www.example.com/foo.bar');

Take a look here: <http://php.net/file_get_conten ts>

Sounds like you could use buffering.
<?php

ob_start(); // Start output buffering.
// Instead of outputting anything, the output is now stored in a buffer.
include('yourfi le.php');
// There, now the file has been included and php parsed.
// It isn't output, it goes into the buffer.
$yourfile = ob_get_clean();
// Now we read everything that has been buffered... And stops buffering.

?>

Result: the file you included has been parsed by the php engine and stored
inside $yourfil, and nothing was output. Sounds like goal achieved.

Re: Read *parsed* PHP file into a variable?

Just discovered http://de.php.net/eval and on that url especially the
user contributed function eval_html3(). But can't get it to work.

I made a simple test page:

http://mueller.zems.tu-berlin.de/~loose/test/test.php

Perhaps you feel like helping to fix the function. (Or to tell me what
I have misunderstood.) I just renamed eval_html3 to eval_html and
replaced <?php by <?. It's now supposed to work but it doesnt. Here
the test files:

test.php:
------------
$s = eval_html(file_ get_contents('. js.php', 0));
$t = eval_html(file_ get_contents('. css.php', 0));

function eval_html($stri ng) {
$string = '<? ?>'.$string.'< ? ?>';
$string = str_replace( '?>', '', str_replace( array( '<?', '<?' ),
'', preg_replace_ca llback( "/\?>(.*?)(<\?|<\ ?)/", "my_eval", $string )
) );
return eval($string);
}
function my_eval($arr) {
return ('echo stripslashes("' .addslashes($ar r[0]).'");');
}

..js.php and .css.php:
------------------------------
contain plain js/ css plus one line
<? $a = 6+7; echo ".testClass { font-size: ".$a."px; }\n\n"; ?>
or resp.
<? $a = 4+5; echo 'testVar = '.$a;; ?>
No errors when called directly.

test.php itself does nothing (blank screen), I only want to get away
the errors. You may also download this small test if you want to
figure it out on your own system (See Link)

Thanx a lot! , Daniel

PS Thx to the other poster, will check your idea out soon as possible.

Better have a look at Kimmo's suggestion, because that's the way to go...

Pretty cool, thanx so much! Never heard of output buffering before.
Yeah...

Guess no need to fight with my other Reply anymore (concerning
eval_html()).

Enjoy, D.

Sounds like you're going to use/eval users' input?--if so, it's a
*serious* security issue. Use output buffering with runkit
<http://in.php.net/runkit>
