In C, etc. one can place #if's around code to determine whether or not
the compiler should pay any attention to the code.

Is there a similar technique for PHP?

I've not seen anything like this before and a brief search hasn't
turned up anything either...just thought I would ask to make sure.

If you are talking about simply commenting code out, yes, I am aware
of this...however, the #if technique is far more capable in certain
situations.

There are reasons why C, etc. has included the ability to comment out
lines of code and also provide #if's.

But based on your reply, I have to assume that PHP does not current
provide such a technique...as I suspected.

in php you have a number of constructs that can be used to execute code (or
not) based on certain conditions ie is_defined(). Not sure if
the comparison with C holds true as C is compiled and PHP is interpreted.

PHP has no built-in macro language. I started to write a pre-processor
a while ago but didn't get very far before the real world forced me to
shelve it, but such a beast is pretty simple to write but obviously is
not evaluated at runtime.

IIRC there was a project a while ago to build a macro language into
PHP but I have no idea how far it got. I think it was being done under
the GSoC initiative. Google should have more on that.

Unfortunately, such things cannot be used to wrap functions.

Surrounding a bit of code/function in an if statement in PHP does the
same thing as the #if in C because PHP is interpreted.

In C, if the #if is true then the compiler compiles the code and when
you execute the binary the code is executed, if the #if is false then
the code is not compiled so it can't execute because it isn't there.

In PHP, if you execute the script and the if is true then the code
executes, if the if is false then the code doesn't execute.

Same same...

Erm, yes they can. Try it.

<?php
if (rand(0,1) == 0)
{
function arse()
{
echo "arse 1\n";
}
}
else
{
function arse()
{
echo "arse 2\n";
}
}

arse();
?>

Oh, sorry, apparently there are some invisible characters in the text
you pasted which I had to zap first. Yes, this does work as expected.

However, try wrapping the arse function in a class.

<?php
class TestClass
{
if ( rand(0,1) == 0 )
{
function arse()
{
echo "arse 1\n";
}
}
else
{
function arse()
{
echo "arse 2\n";
}
}

}

$myVar = new TestClass;

$myVar->arse();
?>


That fails with:


Parse error: syntax error, unexpected T_IF, expecting T_FUNCTION in /
Users/Eric/Sites/ifWrapping.php on line 4

Never tried it in a class. There is probably a way to hack and get it
to work. However, unless you're doing something so much more
sophisticated than most people, what's wrong with this?

<?php
class TestClass
{
function arse()
{
if ( rand(0,1) == 0 )
{
echo "arse 1\n";
}
else
{
echo "arse 2\n";
}
}
}

$myVar = new TestClass;
$myVar->arse();
?>

OK, here's how it goes:

<?php
if(!defined('_THIS_PHP_FILE_PHP')) {
define('_THIS_PHP_FILE_PHP', true);

// define your classes and functions here


} // endif _THIS_PHP_FILE_PHP
?>

In my experience there are very few valid reasons for conditionally
defining functions, and even fewer for conditionally defining methods
in a class. Maybe if you explain what you're trying to achieve we can
you find a better way.

Mmmm... why would you want to use a different class definition on some
conditions? Yes, there might be reasons, but it's usually just a matter of
realizing that you can use inheritance, containment or some design patterns
(say, the Adapter pattern).
There are other ways to solve the problem which are not yet available in PHP.
Some of them are being discussed nowadays
(http://wiki.php.net/rfc/nonbreakabletraits).
Now, if you want something weird... I believe this would work:

<?php
ob_start();
?>
class TestClass
{
<?php
if ( rand(0,1) == 0 )
{
?>
function arse()
{
echo "arse 1\n";
}
<?php
}
else
{
?>
function arse()
{
echo "arse 2\n";
}
<?php
}
?>

}
<?php
// Fetch class definition in the output buffer;
$classDef = ob_get_clean();
// Define class
eval($classDef);

$myVar = new TestClass;

$myVar->arse();
?>

I didn't test this, but it should work I think... I remember nuSoap doing
something similar for soap proxys (though not using output buffering). There are
alternatives that are way better (and smarter about performance) than this,
but... you see... everything can be done in PHP.

If you look for "build-like" tools, that is, generate code at "deployment-time",
you may try phing http://phing.info.

This is part of the C compiler pragmas. But I am relatively new to
the PHP language, but I don't believe PHP supports pragmas.

I use pragma all the time in my C/C++ code. When testing or exploring
logic, I just surround code with if (true|false) {} wrappers and might
use defines as well, example:

define("USE_SPECIAL_CODE", false);

....
if (USE_SPECIAL_CODE) {
} else {
}

or something like:

if (0)
{
original logic
}
some new version of your logic

Yes, not the same thing. But you if you are distributing this stuff,
unless the logic is an useable and optional part of the application,
you don't want to include these snippets in your distribution anyway.
After all, PHP is not distributed as compiled code ... not yet
atleast. :-)
