[PHP] Shorter way for "each"
Hi,
is there a shorter way to do:
while (list($key, $value) = each($my_array))
{
echo $value...
}
I just need the value!
Thanks,
Mo.

Hey Wico,
> echo implode (' ', $array);
this is quite a cool idea! For example
echo "" . implode("", $my_array) . "";
would save some time, printing out an select-group...
Thanks a lot, also to all other people, who helped me.
Mo.

.
What is that?
a) a variable; then you must write $row[$vir_dir_name]
b) a string; then you should write $row["vir_dir_name"]
You should know, that variables from outside a function are not visible
inside a function:
$name = "Moritz";
function print()
{
echo $name;
}
will produce *nothing*;
Instead you must write it like:
$name = "Moritz";
function print()
{
global $name;
echo $name;
}
(normally a function should not access a variable from outside, but
sometimes there is no other way...)
Hope it helps,
Moritz.

[PHP] cool OOP-phenomena!
Hi list,
this is not a problem, but a nice feature of OOP, I found today. Maybe it is
useful for someone:
name . "";
}
}
class Basis_A extends Basis
{
var $name = "Basis_A";
}
class Basis_B extends Basis
{
var $name = "Basis_B";
}
$my_basis_1 = new Basis();
$my_basis_2 = new Basis("A");
$my_basis_3 = new Basis("B");
$my_basis_1->print_name();
$my_basis_2->print_name();
$my_basis_3->print_name();
?>
The point is, that the class morphs itself into another class in the
constructor.
Hope it helps someone,
Moritz.

RE: [PHP] File Uploading Security - Urgent please
$userfile_type
contains the MIME-type of the file. This is maybe more relieable then just
the extension...

RE: [PHP] problem with rewind 2
Jorge Inti Benites RocheThe manual says:
"
The file pointer must be valid, and must point to a file successfully opened
by fopen().
"
"file" not "url".
P.S.: please no HTML-mails.

RE: [PHP] Question about phpinfo() and XML
grrr. XML means 'eXtended Markup Language' and is not a client side language, but a language specification - say: standard. Many 'languages' derrive this standard, such as WML, XHTML and many other data exchange file-types. XML active means, that the XML-parsing functions will work with your PHP. read more about XML on http://www.w3c.org Mo. > -Original Message- > From: Noah Spitzer-Williams [mailto:[EMAIL PROTECTED]] > Sent: Friday, January 12, 2001 6:13 PM > To: [EMAIL PROTECTED] > Subject: [PHP] Question about phpinfo() and XML > > > phpinfo reports that XML is 'active' but i thought xml was a client side > language? what does it have to do with the server? > > thanks! > > > - Noah > > > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > To contact the list administrators, e-mail: [EMAIL PROTECTED] > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
