May make more sense to use parse_url() than explode.

"This function is not meant to validate the given URL..."
I would use parse_url() after URL validation.

Shawn meant to use parse_url() in place of your explode statement. He didn't
say to use parse_url() as a method to validate the url.
He said it would make more sense to do the following.
Also, use strict type matching if you want to compare against boolean(FALSE)
$allowed = array('http', 'https');
$scheme = parse_url($url, PHP_URL_SCHEME);
if (FALSE === in_array($scheme, $allowed) {
// Protocol not valid!
exit(1); // or return FALSE; whatever...
}
Seems a little less muddy to me.

Hello,
I try to code a Webinterface to access my Server @home which has a
couple of UNIX users.
However, I like to have only one website where users must go to whatch
the content of there Folders, which mean, I need a maping which is not
the problem but how must I make the Login/Passwd process, that I get
the right users ${HOME} and can work on it?
I have found one suggestion in the php-general archive, but this is a
very huge monster I do not want to use (>40 MByte only to authentcate?)
Thanks

Unfortunately not, I have only one server on my DSL and using
ssh on the same host has a poor performance. I have tried it
already and each download or directory change takes ages...
SSH need arround 2-7 seconds to respond to a new connect.

Not PHP-related, but you might want to try adding "UseDNS no" to your
sshd_config file on the server. SSH connection delays are commonly caused by
SSHd doing an rDNS lookup for a non-existant record. Turn that off and you
might see an improvement in connect speed.

I have functions that I'd like to benchmark and compare. What are the
best PHP libraries or websites to do that? Something like jsperf.com but
for PHP would be ideal.

You're not going to find a service that will let you do that - allowing
arbitrary PHP to be entered into a website to be executed is far too
dangerous.
Just knocked this up, should do what you want:

I would have thought so too but I found these:

That's surprising, but reading around those sites a little it seems they're
running the code in isolated virtual machines which are firewalled to
prevent outgoing network connections. Very nice!

Hi all,
Up to this point we have been running PHP as an Apache 22 module.
We would like to rebuild PHP over the next few weeks to run it as a CGI/CLI
PHPSuexec system.
I am hoping there may be others that have made this migration and might have a
step by step how to (so far research shows it should be reasonably simple to
do), and would be willing to share it.
Right now we have
FreeBSD 8.0
Apache22 built from ports, with apache suexec enabled,
PHP5 Built from ports,
Any hints are appreciated,
-G

PHP in CGI sucks at performance, you should give a thought to fastcgi +
php + suexec as in here: http://forum.linode.com/viewtopic.php?t=2982
Though its written for ubuntu, you can derive some tricks from there.
I don't know if php-fpm + suexec is possible. php-fpm is best for fastcgi.

Hi all,
I wrap pecl-memcache into a class used as a sigleton class .
the code is :
==================================================code===================================================================================
class Mem{
private static $_instance = null ;//singlton object instance
private function __construct(){
global $config ;
$servers = $config['memcached'] ;
$mem = new Memcache ;
foreach($servers as $server){
$mem->addServer($server['host'],
$server['port'], intval($server['persistent']) > 0 ? 1 : 0,
intval($server['weight']) > 0 ? intval($server['weight']) : 1 ) ;
}
return $mem ;
}
private static function getInstance(){
if(self::$_instance === null || !(
self::$_instance instanceof Mem ) ){
self::$_instance = new Mem() ;
}
return true ;
}
public static function get($key){
self::getInstance() ;
return self::$_instance->get(md5(strtolower($key))) ;
}
public static function set($key, $value, $ttl=0){
self::getInstance() ;
$compress = (is_bool($value) || is_int($value)
|| is_float($value)) ? false : MEMCACHE_COMPRESSED ;
return
self::$_instance->set(md5(strtolower($key)), $value, $compress, $ttl)
;
}
public static function rm($key){
self::getInstance() ;
return
self::$_instance->delete(md5(strtolower($key)),0) ;
}
}
===============================================================code==========================================================
and $config['memcached'] is an array contains info about the server .
$config['memcached'] = array('host'=>'localhost', port=11211,
persistent=1,weight=1) ;
when i run this , i got "Segmentation fault" ! I cannot figure out
what's the problem . any commet appreciate .
and i used memcached 1.4.5 , and libevent-1.4.13-1
php 5.2.16

sorry, the right $config['memcached'] variable is
$config['memcached']=array(array('host'=>'localhost', port=11211,
