php regex to remove HTML

- by Me1000

Before we start, strip_tags() doesn't work. now, I've got some data that needs to be parsed, the problem is, I need to get rid of all the HTML that has been formated very strangely. the tags look like this: (notice the spaces) < p > blah blah blah < / p > < a href= " link.html " > blah blah blah < /a > All the regexs I've been trying aren't working, and I don't know enough about regex formating to make them work. I don't care about preserving anything inside of the tags, and would prefer to get rid of the text inside a link if I could. Anyone have any idea? (I really need to just sit down and learn regular expressions one day)

php: replacing double <br /> with </p><p>

- by andufo

i use nicEdit to write RTF data in my CMS. The problem is that it generates strings like this: hello first line<br><br />this is a second line<br />this is a 3rd line since this is for a news site, i much prefer the final html to be like this: <p>hello first line</p><p>this is a second line<br />this is a 3rd line</p> so my current solution is this: i need to trim the $data for <br /> at the start/end of the string replace <br /><br /> with </p><p> (one single <br /> is allowed). finally, add <p> at the start and </p> at the end i only have the 3rd step so far. can someone give me a hand with steps 1 and 2? function replace_br($data) { # step 3 $data = '<p>'.$data.'</p>'; return $data; } thanks! ps: it would be even better to avoid specific situations. example: "hello<br /><br /><br /><br /><br />too much space" -- those 5 breaklines should also be converted to just one "</p><p>"

how to exploit vulnerability of php?

- by Dr Deo

i have never seen a buffer overflow exploit in live action. supporse I have found a server that seems to have vulnerabilities. Where can i get proof of the concept code preferably in c/c++ to exploit the vulnerability? eg i found this vulnerability Multiple directory traversal vulnerabilities in functions such as 'posix_access()', 'chdir()', 'ftok()' may allow a remote attacker to bypass 'safe_mode' restrictions. (CVE-2008-2665 and CVE-2008-2666). How can i get proof of concept code for educational purposes PS I am a student and my only desire is to learn

Dynamic inheritance/implementation in PHP 5.*

- by Rolf

Hi everyone, I'm implementing a Logger, based on a XML declaration (path to class, method name, custom log message). There is also a Logger interface that defines the function __call, the latter logs what's needed and then relays the call to the target method. The only difficulty is to make each class, declared in the XML file, implement this interface with __call. So finally my question: is there a way to set at runtime the parent class or the implemented interface of another class ? Thanks in advance ! Rolf

PHP script loading took over 10 seconds

- by Misiur

My again. I've promised to not come back today, but I've got another trouble. http://www.misiur.com/me/ - it took over 10 seconds to load. Whole site code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="pl" lang="pl"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>{site('title')}</title> <link rel="stylesheet" type="text/css" href="{site('themeDir')}/global.css" /> </head> <body> <div id="site"> <div id="footer"> <p>Site Managment System {site('version')} by <a href="http://www.misiur.com">Misiur</a>. Copyright © 2010-{$currYear}.</p> </div> </div> </body> I think the trouble is in this piece of code: private function replaceFunc($subject) { foreach($this->func as $t) { preg_match_all('/\{'.$t.'\([a-zA-Z,\']+\)\}/i', $subject, $res); for($j = 0; $j < sizeof($res[0]); $j++) { preg_match('/\([a-zA-Z,\']+\)/i', $res[0][$j], $match); if($match > 0) { $prep = explode(", ", substr($match[0], 1, -1)); $args = array(); for($i = 0; $i < sizeof($prep); $i++) { $args[] = substr($prep[$i], 1, -1); } } else { $args = array(); } $subject = preg_replace('/\{'.$t.preg_quote($match[0]).'\}/i', call_user_func_array($t, $args), $subject); } } return $subject; } It has to find functions from array ($this-func), cut out arguments, and call function with them. I think that I've messed up. Help.

Displaying untrusted HTML using PHP

- by esryl

I have a read a number of excellent questions and answers today about dealing with user input. I am now using htmlspecialchars() to display user data in the create/edit forms (but accepting the raw input via prepared PDO statements into my database). The main question I know have is, what do you do when you are allowing the user to submit HTML which will then be displayed to the public. Obviously htmlspecialchars() is no longer suitable as it just encodes the tags and renders the content useless for purpose. My application is currently accepting HTML from an admin for product descriptions. This would allow a malicious admin to inject potentially unsafe data into public facing pages. How do people cope with this?

URL flow when writing a wizard in PHP

- by Brian

Hello, I am writing a basic wizard for my web site. It will have 4 steps, and each needs to have its own URL. Each step must first validate a form before moving on. If the form for a given step fails to validate, I don't want the URL to change. But if it passes, I do want it to move on. What is the preferred way to write this? Using javascript alone to validate is not secure enough. I have 2 ideas so far but I don't love either: 1) Post the form to the same script and use a header() redirect to the next step if it passes. 2) Send an ajax post to validate and then use location.href to send user to the next step if it passes. Is there a better way to do this? Thanks, Brian

I need some help cropping an image in PHP (GD)

- by evan

http://i.imgur.com/foT9u.jpg Using that image as an example, here's what I need to do: Crop the blue square to have the same proportional ratio as that of the black square From doing that, I should then be able to resize the blue square to fit into the black square without losing stretching it - It'll retain its proportions. Note: The blue square must be cropped 'from the center'. The original center should remain the center after the crop (it can't be cropped from the top left, for example). Here's what I'm thinking needs to be done (using the, landscape, blue square as the example): Figure out the difference between the black squares width and height Figure out the difference between the blue squares width and height This should tell me how much to crop the blue square by and with how much of a 'top offset' Once it's cropped to fit the black squares proportions, it can then be resized I've been messing around with code similar to: if (BLACK_WIDTH > BLACK_HEIGHT) { $diffHeight = BLACK_WIDTH - BLACK_HEIGHT; $newHeight = $blue_Height - $blue_Height; echo $newHeight; } And using Photoshop to try and get a feel for how this should be done, but it continues to fail .< How should I go about doing this? How can I figure out how much to crop by (depending on if the blue square is landscape or portrait)? How do I then get the offset to retain the blue squares center?

PHP Image Upload object won't create directory on windows

- by ThinkingInBits

I'm writing a class that excepts a product_id and a $_FILES array as it's constructor. The class saves these variables and uses them to create a new directory named by product_id and attempts to copy the temp file to my specified directory. For some reason my class isn't even getting as far as creating a directory (which should happen in the constructor) Here's a link to my code: http://pastie.org/955454

PHP anonymous functions scope question

- by Dan

Hi, I'm trying to sort an array of objects by a common property, however I cannot get my $property parameter to register in the inner function (I can use it in the outer one OK). The way I read the documentation, it sounded like the parameter would be available, have I misunderstood something? Here is what I have: public static function sortObjectsByProperty($objects, $property) { function compare_object($a, $b) { $a = $a->$property; $b = $b->$property; if ($a->$property == $b->$property) { return 0; } return ($a->$property > $b->$property) ? +1 : -1; } usort($objects, 'compare_object'); return $objects; } Any advice appreciated. Thanks.

PHP, display image with Header()

- by user271619

I'm displaying images from outside my web root, like this: header('Content-type:image/png'); readfile($fullpath); The content-type: image/png is what confuses me. Someone else helped me out with this code, but I noticed that not all images are PNG. Many are jpg or gif. And still they are displayed successfully. does anyone know why?

Call a constructor from variable arguments with PHP

- by zneak

Hello guys, I have a function that takes variadic arguments, that I obtain from func_get_args(). This function needs to call a constructor with those arguments. However, I don't know how to do it. With call_user_func, you can call functions with an array of arguments, but how would you call a constructor from it? I can't just pass the array of arguments to it; it must believe I've called it "normally". Thank you!

PHP manipulating multidimensional array values

- by Joker

I have a result set as an array from a database that looks like: array ( 0 => array ( "a" => "something" "b" => "something" "c" => "something" ) 1 => array ( "a" => "something" "b" => "something" "c" => "something" ) 2 => array ( "a" => "something" "b" => "something" "c" => "something" ) ) How would I apply a function to replace the values of an array only on the array key with b? Normally I would just rebuild a new array with a foreach loop and apply the function if the array key is b, but I'm not sure if it's the best way. I've tried taking a look at many array functions and it seemed like array_walk_recursive is something I might use, but I didn't have luck in getting it to do what I want. If I'm not describing it well enough, basically I want to be able to do as the code below does: $arr = array(); foreach ($result as $key => $value) { foreach ($value as $key2 => $value2) { $arr[$key][$key2] = ($key2 == 'b' ? $this->_my_method($value2) : $value2); } } Should I stick with that, or is there a better way?
