works as well :) I don't like those kinds of things for this purpose
because it takes longer for people new to the code to read and
understand it than, say
,

(which in my case does a pretty meaningless conversion)
No, I was just wondering whether I had missed some construct in the
language that might the conversion for me, and be obvious to
PHP-heads. No problem that there doesn't seem to be.

Re: [PHP] Re: My truth comes out [1]
I would stay clear of the ternary operator in nested coditions, for
obvious reasons. If it can fit in a single line and is essentially
clear in its message I dont see why not to use it.

If you are worried that it takes longer for people new to the code to
read and understand then add comments! If it is about readability then
give them something to read. You could even create a function that is
more readable than the 'if' alone;
$foo = booleanString($string);

This is why in PHP you can create functions and libraries...
?php
function string2bool( $string )
{
return preg_match( '#^(1|true|enabled|on|active)$#i', $string );
}
?
I used a preg_match because I have my doubts 2.5 calls to strcasecmp()
would be faster... but who knows... the above example also happens to be
very succinct* if not optimal :)
* Yes, I know, nobody asked for the other options, but I like the
flexibility and many ini files do too.
Cheers,
Rob.
