For me, special chars escapement (like ', ", \) about eval's argument is messy and
leads many syntax errors.
How about out buffering technique like below ?
------------------- sample.php ------------------
<?php
ob_start();
$i = 0;
?>
global $i;
$i++;
return "Hello, World! + [$i]";
<?php
$_code = ob_get_contents();
ob_end_clean();
echo eval($_code)."\n";
echo eval($_code)."\n";
echo eval($_code)."\n";
?>
-------------------------------------------------
It will be:
$ php hoge1.php
Hello, World! + [1]
Hello, World! + [2]
Hello, World! + [3]
Above technique, source is more readable and we don't need to pay attensions about escapement
any more.
Regards, request for comments.
