Hello,

I am trying to use preg_match to match something from an html file. Within the
html file is some text that looks like:

<span>Something, something end</span>

I know that the text ends 'end', but I don't know what the Something, something
is. I am using preg_match as follows:

preg_match('/[^>]*end/',$curl_response,$matches);

I want to match 'end' and everything before it that is not '>'.

The problem appears to be with the '>'. I have tried escaping (\>), but it
didn't make a difference. The php script hangs when it tries to run this 
function.
You didn't say the phrase is always enclosed in <span> tags; but I assume it is not. This will handle any tags.
Try this pattern "%<[^>]+>(.+)\s+end\s*</%i" Note the % instead of "/" because you need it in the pattern. Also, the \s are in case there are extra spaces.
Use print_r on your $matches. If you expect more than one, then use preg_match_all()

That did it.  In my case, I know that the first letter is capitalized, so I 
used:

preg_match('/[A-Z][^>]*end/', $curl_response, $matches);

Thanks for your help.

Good lord. I'm glad the U.S. Congress has not gotten together to pass
laws about how we build websites here. I'm not sure I could take
less-than-bright government bureaucrats telling me how to do the job of
programming. No offense, Ash, but you can keep your parliament.

Yeah, it's been such a pain, as nobody over here is quite sure how the
hell it'll be enforced either, or if it even will be. It's also pretty
vague as to just where the line gets drawn. The official government
sites on this are pretty black and white, but don't clearly address the
grey areas. I think this is definitely a case of the persons making the
laws don't understand the technology involved, which sadly seems to be
the case across a lot of tech laws being passed world-wide of late :(

Yep,  When this law was discussed, they were mostly talking about
completely banning cookies. Only later they figured out that there are
quite a few sites that can't live without cookies...

Hi all,

I have a colleague stuck with this thing named "Hungarian Notation"
http://goo.gl/xYv8O
We try to define our internal coding standards, which is very close to the Symfony ones http://goo.gl/f2rcO
But we're in conflict because the colleague really argue about his "Hungarian Notation".
Have you got some ressources arguing against this? I ran out of mine to convince him...

The two don't look to be mutually exclusive, but Hungarian notation doesn't 
make much sense to me for php. Php is a loose typed language, and variables can 
(and do) change their types often. Consider even the internal php functions 
which can return booleans, or arrays or strings, all from the same function. 
Using Hungarian notation to give the dev a hint about the various types doesn't 
make much sense, and may give the dev a false sense of security.

Thanks,
Ash

Sure, they're not.
It's not forbiden to "prefix" variables.

That's the first point I told him. No way: for him it's syntaxically compliant.

Take a look at http://en.wikipedia.org/wiki/Hungarian_notation which shows that quite a few 'big' names are against it.
I personally hate it because it ties a variable to a particular type, which in PHP is useless as a variable is allowed to change its type 'on the fly'. Even in a strongly typed language it can cause problems - I remember many years ago having a variable called $numCustomerId because CustomerId was supposed to be numeric. Then it transpired that it could actually contain alpha characters, so it had to be a string and not a number. Changing all occurrences of $numCustomerId to $strCustomerId was a royal PITA, but it would have been totally confusing to allow alpha characters in a variable that was supposed to contain nothing but numbers.

Hungarion notation just doesn't make sense in PHP. You should not even
try to convince him, if he doesn't understand this, then you might be
better off finding another colleague ;)

This simply adds far too much noise to code. If I need to know what type a 
variable has, I'll look at its declaration, if any.

Hi.

I've got a piece of code that builds up a multi-meg test array for my
opensourced http://mediabeez.ws/products/htmlMicroscope var_dump()
improvement, and when I run it for longer than about 20 minutes, the
browser just calls it quits.. :( Firefox, and chrome.

I'd like to do this with a browser call, if all else fails I suppose I
can run the generation of the test array from the commandline, but I
prefer calling from the browser..

So, I'm doing ob_start(), then start the main loop which does echo
'.'; ob_flush(); flush();.

I've got my KeepAliveTime set to 25 seconds, as per
http://www.pctools.com/guides/registry/detail/891/

And I'm calling this from my browser to the domain name that points
back to the machine I run the browser on, latest wampserver on windows
7.
Calling via localhost doesn't work somehow.

Is there anything obvious I've missed?

Just to be sure, have you checked the Apache error logs for anything
obvious? (eg. out of memory?)
In case the browser closes the connection, you could use
ignore_user_abort [1] to be sure the script continues, though the
browser won't receive the result.

I have run into an error when performing a conditional using iplong() and the ~ bitwise operator 

$ip = '0.0.0.0';
$mask = '24';

$end = (ip2long($ip) || (~ip2long($mask))) + 1;

PHP Fatal error:  Unsupported operand types

I even tried to typecast the mask to (int)

The error is probably not where you suspect it to be. ip2long will
return false for ip2long($mask), because $mask is not a valid IP
address. The ~ operator is not supported for false.

Strange... this works

$ip = '10.0.2.0';
$mask = '24';
Anything using 0.0.0.0 fails using the bitmask to calculate valid CIDR ranges.

Yes, because with $ip being 0.0.0.0, the result of ip2long($ip) will
be zero. Zero evaluates to false when PHP is going to parse the ||
operator, and because of that, it continues to parse the rest.
When the result of ip2long($ip) is greater that zero, in case of some
other valid IP, it will evaluate to true and PHP will not even execute
the rest after the || because the result will be true anyway.
Did you mean to use a single | operator, as a bitwise OR?

I'm working with a third-party PHP extension that makes a call to
zend_auto_global_disable_jit. However, in PHP5.4.5, there is no
zend_auto_global_disable_jit available, nor is it in its traditional
header. Commenting out all zend_auto_global_disable_jit calls causes
PHP to no longer recognize it as a valid extension, while leaving them
in attempts for an invalid method to be called.

The file in question is
https://github.com/mtorromeo/runkit/blob/master/runkit.c line 305. As
is relatively obvious, it's not part of a macro, and its removal
should not affect whether the library is a PHP extension or not -
perhaps it's based on PHP's static analysis? If it doesn't call the
function, it would access a global, possibly before the global has
been JIT initialized by the runtime. If this is the case, what is the
replacement function for PHP 5.4.5?
