Not sure about others, but I spend lot of time to solve the following problem:
I have some, for example, translation data
(f.e.: $lang['Message'] = "Hello, $User!";)
and I'd like to replace variable '$User' with it's actual value
(f.e.: 'Vasya Pupkin')
and get hall translation string back with replaced variable
(f.e.: $lang['Message'] = "Hello, Vasya Pupkin!";).
So, at the end of all this I wrore function, that fix 'eval()'s unability to return
evaluated string.
So, that is:
==================================
<?php
function evaluate ($Source = NULL) {
eval("\$Output = \"".addslashes($Source)."\";");
return $Output;
}
?>
==================================
Example:
<?php
$User = 'Vasya Pupkin';
$lang['Message'] = "Hello, $User!";
$Result = evaluate($lang['Message']);
?>
will print 'Hello, Vasya Pupkin!'.
Hope, this will help someone...
