Given that, for example, array_search and strstr take those arguments

I read it that he could never remember which order to put them in.

There's no reason why HTML with single-quoted attributes isn't valid, so in
principle your expected output of
a href='index.php?page=services'services/a
should be OK.
The real challenge is to understand why the code fragment you have presented is
losing the single quotes: are you *sure* this is exactly what you have in your
file (i.e. have you copied it to the posted message properly) ?

This is because you misspelled $categorys, where it should
actually be $categories.

Jim,
Not to be a smart ass like Danial was (which was brilliantly written
though), but you have your example formatted incorrectly. You are
using commas instead of periods for concatenation, and it would have
thrown an error trying to run your example. :)
# corrected:
echo lia href=\index.php?page={$category}\{$replace}/a/li;

Steve Staples.
Steve,
The commas are not concatenation. They are separators for the echo construct.
I don't know the internals well enough, but ...
echo $a.$b.$c;
vs
echo $a, $b, $c;
On the surface, the first instance has to create a temporary variable
holding the results of the concatenation before passing it to the echo
construct.
In the second one, the string representations of each variable are
added to the output buffer in order with no need to create a temp var
first.
So, I think for large strings, using commas should be more efficient.
Richard.

David:
First of all, the type (strict or transitional)
of DOCTYPE doesn't matter -- it only matters IF
you are going to use deprecated HTML elements
(transitional) or not (strict).
Second, your li (i.e., list) should start with
a type of list tag, such ol for ordered list
-- there are several different types (i.e., ol,
ul, dir, menu, dl dt dd).
Third, you might try this:
echo(lia href=\index.php?page=$category\$replace/a/li);

[PHP] Array Symbol Suggestion
I'd like to make a suggestion for a change, or possibly an addition, to the PHP language. I'm learning PHP and have been very excited with what it can do in relation to HTML. But when I got to the part about arrays, I was disappointed to see that they are designated with a $ the same as other variables. I was learning Perl before I switched, and it uses the @ sign to designate an array. That makes it a lot simpler to see at a glance what is an array and what isn't - at least for beginners like me. Has there been any talk of adopting the @ sign for arrays in PHP? Or is that symbol used for something else that I haven't read about yet? What is the proper channel for making suggestions like this?

Thanks, Marc Hi Marc, I'm a PHP n00b as well and had similar thoughts regarding this.. just imagine two variables called the same thing.. a string and array.. and accidentally resetting one.. $oops = something; however, from my experience, there is often this kind of problem in any language, and that is where naming conventions come in very handy. I don't know if the PHP community has any standard convention.. but I would suggest something like: $a_foo (for arrays) $f_foo (imploding into form variables) $s_foo (string variables) $db_foo (variables coming from databases perhaps) etc.. This way, you'd never be confused of the origin of the variable. Donovan -- D Brooke -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

PHP is a loosely typed language, so you can have a variable that,
throughout its lifetime in an app, is both a scaler (integer, string,
etc) or an array. For example:
?php
$message = hello world;
echo $message;
$message = array('hello', 'bob');
echo {$message[0]} {$message[1]};
?
There are functions you can use to determine the type of a variable,
such as is_string() and is_array() and you can use var_dump() in debug
statements to quickly see the type of a variable. I think changing
something as integral as a variable prefix would break a lot of code
which makes use of the loose typing, and would cause much more confusion
further down the line.
Also, as you may have guessed, the @ symbol is already in use at the
moment. In PHP it ensures that minor errors are silently ignored. For
example:
@executeSomeFunction()
would run that named function, but ignore any minor errors and warnings.
You'll typically find it used a lot in calls to mail() as that can be
flaky on some systems due to a number of factors outside of PHP.

Ash

Thanks, Ash http://www.ashleysheridan.co.uk I fully agree with you on php.net being some of the best documentation out there.

[PHP] Closure and $this
Hello, Does anyone know if closures will ever support the $this keyword? I think it would be very useful when working with objects. Best regards__RaymondDo more with less - http://raxanpdi.com

So, in other words, your closure does not belong to the class you declare it in, but the Closure class. Thus, if it supported the $this variable, it would refer not to the class you want, but instead to the Closure class. Just my understanding. If it's not right, someone point it out. -- Greg Bair PHP Developer -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Actually at one point early on they did support a $this, but the way it was bound to an object was half-assed and incomplete so it was removed entirely from 5.3. The intent was to then properly think through how that binding should happen and re-introduce it properly in 5.4. I believe a consensus was reached on how that should happen but I'm not sure what its implementation status is at present.

I realize this would be a major change, so that's why I also mentioned it as an addition to the language. I'm sure it's just what you're used to, but still being new to all this, it just makes sense (to me anyway) to have different symbols for different variable types: $scalar @array #hash Since the @ sign is already reserved, maybe there's another symbol that would work better? I don't know. These are just ideas that I came up with while reading and I thought I'd throw it out there to see what others thought. I like the idea of a naming convention, so that's what I'll do in my scripts. I also appreciate the heads up on is_string(), is_array(), and var_dump(). Thanks again, Marc If you check out the manual pages for those functions as well, you'll see other related functions. I must say, of any language I've used, the php.net documentation is by far the best, giving plenty of information and user comments too. It's a resource I still can't do without, and I reckon even the old hands on this list would say the same. Yes, I wouldn't want to be without my local php.net mirror. Other languages that can easily match the quality of the documentation - assembler, C and C++, to name a few. -- Per Jessen, Zürich (7.9°C) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
