That won't work, because you escaped the $ sign, the variable won't get
processed and the name returned w
If I have a variable, how do I extract the name of the variable.
In principle:
$varname=somefunction($myvar);
The value of $varname is then "myvar"
How do I do it?

You have twice "action" and are missing the "method".
In your case, I guess it would be "get".

I include files in each other all the time, and some of them might call the
same functions (like database functions).
I just use a string in all function declaration with the name of the
functions or set of functions in the file.

$function_test=1;
function test()

I wrote a php pipe that allows people to play Zork from their browser
http://phpzork.com
Zork is a 20 years old command based adventure games. One of the first and
most popular. It's source code was released. Many of us here should remember
it.
For those who don't know how to play, just type y
Check the link I posted.

There is the code I wrote and it's output.
The two lines print.
You can explain me why tomorrow they print on my server and not yours.

You are right, "0" didn't show as a value.
But his two lines still don't need typecasting, they both work:

No it doesn't have a value.
PHP interprets 0 as null.
A very easy way for you to check:
$value=0;
if(!$value) printf("$value doesn't have a value (it didn't even print
0)\n");
$value="0"
if($value) printf("$value
I just tested those two lines with php 4.0.6 and they both work.
There is a difference though.
If you set $qty=0; then $qty has no value.
But if you set $qty="0", it has a value.
Type casting is irrelevant in php.

Try
ereg("^[:space:]\**$",$variable)
or
ereg("^[ ]*\**$",$variable)
or

Well, php runs the same as apache, so whatever apache can access, php can
access.
So any files with the db passwords that need to be accessed by php, can be
seen by all users who can upload php scripts to your server. In the case of
virtual hosting.
So trust people you give access, even limite

No, he wants to launch a script after Javascript has processed.
PHP is run on the server, Javascript on the client so Javascript has to run
after PHp is finished.
For him to launch a Javascript code, he can only do it by con
