$i=0;
foreach( $arr2 as $val2)
{
$findme = 'http';
$pos = strpos($val2, $findme);
if ($pos === false)
{
$arr2[$i] = $val2;

The slashes are used as modifiers to mark the beginning and the end of the
pattern, but they are also used in the pattern itself.
You can fix this by escaping the slashes in the pattern:
$tresc = preg_replace('/(http)(s?)(:\/\/)([^ ]+)/', '<a
href="$1$2$3$4" >$1$2$3$4</a>', tresc);
Or by using another modifier:
$tresc = preg_replace('# (http)(s?)(://)([^ ]+)#', '<a
href="$1$2$3$4" >$1$2$3$4</a>', tresc);

No -- the slashes are used as *delimiters*. The *modifiers* are any extra
characters that occur after the end delimiter. For example:
/foo/i
will match 'foo' case-insensitively. In this example, the 'i' is a
modifier -- it modifies the behaviour of the regular expression to make it
case-insensitive.
Specjal's warning is caused by the third slash. PHP sees the second slash
as the end delimiter, which makes any trailing characters modifiers.

Yeah, you're right.

I'm probably missing something rather obvious, but is there a known
problem with getting a Python based socket program to communicate with
a C based socket program? A simple echo server written in Python
(the example from Python in a Nutshell actually) will happily talk
to a Python based client. If a C based client is substitued the connection
is refused (or so the C client reports). The C client will talk to
a C server.

We have a multi-line textbox that users copy and paste email text into. The
pasted text frequently will contain a tag like <blah@aol.com> or similar. I
believe .NET is protecting itself from code injection by throwing a global
error when this occurs. The exception message is pasted below.
We will NOT be able to train our users to eliminate all <> tags. What's the
best way to deal with this issue?
Thanks in advance.

At the company I work job applicants are required to do a little test.
The human resource manager recently had a candidate who claimed one of

Dependent upon the version of DB2 one or the other answer of a multiple
choice question could be right, the candidate said.
The HRM asked me to look into the matter, but since I am no expert in
the workings of DB2 I submit the question to you hoping any of you can

I have to find a correct architecture to achieve this XML <=Text

I'm trying to connect to a host that accepts UDP on a port I setup and tested from a command line too called udp_write. However a PHP fsocketopen() call doesn't work nor does it give an error.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
