Bozo said: $r->{'1st_column'} Does object 'members' include methods? eg. Is this valid syntax: $this->{$bool ? 'a' : 'b'}($args); I am hoping it is equivalent to: if ($bool) $this->a($args) else $this->b($args);

This also works with object members, where I had to use this recently to deal with a database wrapper:
$r->1st_column
isn’t valid, but
$r->{'1st_column'}
works as expected.

what about:

$foo = 'hi';

$bar = 'ho';

${$foo . $bar} = 'Yes!'; // Same as $hiho

@Peter – Try NetBeans, it is amazing.

I was trying to clean up some strings tonight and discovered that I can use curly braces within double quotes to concatenate a var with the text immediately following it. It looks much much cleaner than using periods and double quotes. For example, if working a dynamic CSS rule:

background-position: $x_offset”.px.” $y_offset”.px.”

vs.

background-position: {$x_offset}px {$y_offset}px.

…a lot more readable.

Well,

I have a code, what worked in PHP 4.x but didn!t in PHP5.
The code uses the function you mentioned above.

with PHP5 the
print_r(${(‘_GET’)});
line prints the global? $_GET array, while
print_r(${(‘_G’.'ET’)});
gives an “Undefined variable: $_GET” php error.

I have tried to use a whole slew of IDEs in the past and there’s really nothing exceptionally wrong with them. I rather prefer almost just a ‘window’ with the code in (pretty highlighted) and nothing much else.

I remember trying Aptana, Zend, Eclipse, Komodo, PhpED, PHP Designer, PHP Edit–those are the ones I can name off the top of my head–but it was nearly always simply the ‘bulk’ of such applications which put me off. I’m a Zen-like person and they all just made too much noise for my liking!
