include into string

[ludri]

I have a code, it works, prints out

"oneI have dog."
it should works this way
"I have one dog."

[main.php]
$text = "I have include=file dog.";
$text = preg_replace("/include=([A-z]*)/e","eval('?>'.implode ('', file(\1.'.php')).'<?')",$text);
echo $text;

[file.php]
<?
print("one");
?>

Someone know what is the problem?

It looks like the eval isn't doing what you expect. It's printing "one" and returning nothing (which is what the preg_replace put into the string).
