With PHP I would advise you to use the Simple HTML Dom Parser, the best way to learn more about it is to look for samples on the ScraperWiki website.

One general approach I haven’t seen mentioned here is to run HTML through Tidy, which can be set to spit out guaranteed-valid XHTML. Then you can use any old XML library on it.

But to your specific problem, you should take a look at this project: http://fivefilters.org/content-only/ — it’s a modified version of the Readability algorithm, which is designed to extract just the textual content (not headers and footers) from a page.

This sounds like a good task description of W3C XPath technology. It’s easy to express queries like “return all href attributes in img tags that are nested in <foo><bar><baz> elements.” Not being a PHP buff, I can’t tell you in what form XPath may be available. If you can call an external program to process the HTML file you should be able to use a command line version of XPath.
For a quick intro, see http://en.wikipedia.org/wiki/XPath.

DO NOT USE SELF:: use STATIC::

There is another aspect of self:: that is worth mentioning. Annoyingly self:: refers to the scope at the point of definition not at the point of execution. Consider this simple class with two methods:

class Person
{

    public static function status()
    {
        self::getStatus();
    }

    protected static function getStatus()
    {
        echo "Person is alive";
    }

}

If we call Person::status() we will see “Person is alive” . Now consider what happens when we make a class that inherits from this:

class Deceased extends Person
{

    protected static function getStatus()
    {
        echo "Person is deceased";
    }

}

Calling Deceased::status() we would expect to see “Person is deceased” however what we see is “Person is alive” as the scope contains the original method definition when call to self::getStatus() was defined.

PHP 5.3 has a solution. the static:: resolution operator implements “late static binding” which is a fancy way of saying that its bound to the scope of the class called. Change the line in status() to static::getStatus() and the results are what you would expect. In older versions of PHP you will have to find a kludge to do this.

http://php.net/manual/en/language.oop5.late-static-bindings.php

So to answer the question not as asked …

$this-> refers to the current object (an instance of a class), whereas static:: refers to a class

Here is an example of correct usage of $this and self for non-static
and static member variables:

<?php
class X {
    private $non_static_member = 1;
    private static $static_member = 2;

    function __construct() {
        echo $this->non_static_member . ' '
           . self::$static_member;
    }
}

new X();
?>

The keyword self does NOT refer merely to the ‘current class’, at least not in a way that restricts you to static members. Within the context of a non-static member, self also provides a way of bypassing the vtable for the current object. Just as you can use parent::methodName() to call the parents version of a function, so you can call self::methodName() to call the current classes implementation of a method.

class Person {
    private $name;

    public function __construct($name) {
        $this->name = $name;
    }

    public function getName() {
        return $this->name;
    }

    public function getTitle() {
        return $this->getName()." the person";
    }

    public function sayHello() {
        echo "Hello, I'm ".$this->getTitle()."<br/>";
    }

    public function sayGoodbye() {
        echo "Goodbye from ".self::getTitle()."<br/>";
    }
}

class Geek extends Person {
    public function __construct($name) {
        parent::__construct($name);
    }

    public function getTitle() {
        return $this->getName()." the geek";
    }
}

$geekObj = new Geek("Ludwig");
$geekObj->sayHello();
$geekObj->sayGoodbye();

This will output:

Hello, I'm Ludwig the geek
Goodbye from Ludwig the person

sayHello() uses the $this pointer, so the vtable is invoked to call Geek::getTitle().
sayGoodbye() uses self::getTitle(), so the vtable is not used, and Person::getTitle() is called. In both cases, we are dealing with the method of an instantiated object, and have access to the $this pointer within the called functions.

I’m using Phpass which is a simple one-file PHP class that could be implemented very easily in nearly every PHP project. See also The H.

By default it used strongest available encryption that is implemented in Phpass, which is bcrypt and falls back to other encryptions down to MD5 to provide backward compatibility to frameworks like Wordpress.

The returned hash could be stored in database as it is. Sample use for generating hash is:

$t_hasher = new PasswordHash(8, FALSE);
$hash = $t_hasher->HashPassword($password);

To verify password, one can use:

$t_hasher = new PasswordHash(8, FALSE);
$check = $t_hasher->CheckPassword($password, $hash);

NOTE: This answer was originally posted at StackOverflow.com by rabudde

A much shorter and safer answer – don’t write your own password mechanism at all, use one that is tried and tested, and incorporated into WordPress, Drupal etc, i.e. Openwall’s phpass.

Most programmers just don’t have the expertise to write crypto related code safely without introducing vulnerabilities.

See this excellent answer for more about why phpass is the best way to go.

Wow I really didn’t know about this but its not a big code you can try echo “z” after loop Mark is Absolutely Right I use his method but if you want alternative then this may also you can try

            <?php 
                for($i="a"; $i="y"; $i++)
                {
                    echo "$i\n";
                    if($i=="z")
                    {
                    }
                    }
                    echo "z";
            ?>

While the above answers are insightful to what’s going on, and pretty interesting (I didn’t know it would behave like this, and its good to see why.

The easiest fix (although perhaps not the most meaningful) would be just to change the condition to $i != ‘z’

<?php
for ($i = 'a'; $i != 'z'; $i++)  
    echo "$i\n";
?>

Why not just use range('a','z')?

Try this

1) In the wp-config.php add define(‘FS_METHOD’, ‘direct’);

2) Set the “wp-content” directory to 777 for writable.

3) Now install the plugin.

The answer from stereointeractive covers all the options. Just wanted to mention an alternate way of using FTP. I’m guessing that the reason you are not allowing FTP access is for security. One way to address those security concerns is to run your FTP server listening only on 127.0.0.1

This allows you to use FTP from inside WordPress and you will be able to install plugins while not exposing it to the rest of the world. This can also be applied to other popular web applications such as Joomla! and Drupal. This is what we do with our BitNami appliances and cloud servers and works quite well.

I’ve been using WordPress more or less against my will for about two years now (since I started using other frameworks). I think there is no “good Rails alternative”. Of course there are a lot of blog engines but none have as many plugins available or are as well known with clients. Let’s be honest, WP has a fantastic front-end, clients seem to like that. The reason “we developers” look for Rails alternatives is obviously because Rails developer aren’t comfortable with WP. But there’s no platform out there that has the same out-of-the-box completeness and user friendliness as WP. For blog-like purposes that is of course.

You may want to look into Wordscript ; it includes API’s written in Ruby and PHP that connects to existing wordpress databases and returns json structures (made from generated SQL).

Useful if you want to keep full administrative features of Wordpress, and have a somewhat simple Wordpress site. Neither version requires Wordpress to be installed locally, but you can’t really do anything administrative with the api or comments/custom fields (yet). Also the API is much faster and consumes a fraction of the resources Wordpress would.

WordPress fits well for a blogging setting and is relatively easy to adapt. I tried Drupal but I couldn’t get it to play well. I’m still considering what CMS functions best with a workflow of translators in multiple languages.

NOTE: This answer was originally posted at StackOverflow.com by SleekCC

The answer depends on the requirements. WordPress can be an excellent choice if your customer’s budget is very low

If they have some more budget and want something more, the take a look at the CMSes listed above. For ASP.NET I’ve used SiteCore and SiteFinity and have liked both because they allow a lot of flexibility over design and content. Plus, if I need to I can just get into the code and add my own user control to get something hard done.
