Removing Bad Words

Feb 22, 2006

Looking for suggestions on how to handle bad words that might
get passed in through $_GET['item'] variables.

My first thoughts included using str_replace() to strip out such
content, but then one ends up looking for characters that wrap
around the stripped characters and it ends up as a recursive
ordeal that fails to identify a poorly constructed $_GET['item']
variable (when someone hand-types the item into the line and
makes a simple typing error).

So the next thoughts involved employing a list of good words
and if any word in the $_GET['item'] list doesn't fall into the
list of good words, then an empty string gets returned.

Any suggestions on how to handle this?

Removing What Ever String Of Word Or Words Come After A Special Char On A Single Line?

I have a source file that file that contain to be translated strings. Each line of the translation cache files containt a Source string then a delimiter/separatpr █ then the translated string

The original old author did write a nice clean up script that cleans the cache files from duplicates or deletes entire lines from the cache if the old source did not use them anymore. Now I would like to add one more function into that existing code (relevant part below) which is : to delete the entire line when there is absolutely nothing '' coming after the separation key █ for the same line that its examining.I have the feeling it will be 1 line of code somewhere below. But where how does this line look like?


$translation_key_value_separator = '█';

// Read file contents and create a used keys array
$used_keys = array();[code]...

Database Driven - Removing The Navigation Bar Instead Of Removing The Button

I understand Javascript, some intermediate Java, expert html, css, Actionscript. My company has acquired a php-based Web site. It has a button in the global main navigation header that we need to remove. Here is the following script that the php page pulls to populate the global navigation header:

$navigation = @mysql_query("SELECT * FROM navigation WHERE category='main' ORDER BY listing ASC");

Which is then placed into a table by this code:

<table border="0" align="center" cellpadding="0" cellspacing="0">
<td><img src="/_images/nav_divider_white.gif"></td>
<?php while ($nav = @mysql_fetch_array($navigation)) { ?>
<td class="<?php

... remaining original code, etc. Instead of removing the button from the navigation bar, it removes the navigation bar from the page "company" which I thought was interesting but not the achievement I wanted.

Calculate The Number Of Words/characters Between 2 Given Terms/words?

Basically - I want to calculate the "Proximity" of various terms. By "proximity" I means Specifically the number of spaces/characters/words that sit between them.


Terms = Word1 / Word2
Chunk = "blah Word1 blah blah blah blah blah Word2 blah"
Proximity = Word1-Word2:5

THe script would see the 2 terms, locate them and then see the distance based on the words that lay between them. A more advanced version would be to examine the semantic structure - and identify whether the terms occur within the same semantic element, or a sibling, or a parent etc. Thus proximity discovery of terms may be within the same paragraph, or in sequential paragraphs, or under the same "parent" (heading) but otherwise separate etc. Further - introducing things like word stemming/relationships/soundings at a later date may be useful too.

I've looked around the net (Google, here, php forums, php script sites). Not seeing anything like it. I can see tools on some sites that do similar (limited) - usually SEO based tools. I want to be able to apply this to "text" in general ... as I may apply it to uploaded word/txt files etc. I'm not seeing any real examples - so I can only assume it's mroe than a trifle to code it. How would I handle variant order of the words (Word1+Word2 / Word2+Word1)? How could I handle identifying proximity within/outside of the same element/structure?

Bold Some Words In A String And Remove Some Unbold Words?

I am creating an Image Search Engine. Currently, my script does bold the matching words on the keyword. But, some keywords are too long just like the followings. When I search for shah rukh khan, there is an image with the following keyword.

25216d1235653089 shahrukh khan s
wallpaper shah rukh actor

As you see, the above keyword is too long. So, I need it to be like the following one.


Currently, I am using the following code but it requires a space before and after the bold tags. So, if the 1st word is bold, it displays the whole keyword.

$img_keyword = preg_replace('/(.*?) <b>(.*?)</b> (.*?)/us'," <b>$2</b> ",$img_keyword);

Replace Words - Ignore Words Between Brackets?

I'm using an ubb parser to convert several codes within brackets to html codes. I want to use a string replacer aswell to replace some unwanted words.

Now, I'm using this:

foreach($f AS $value) {
$escapeNamesArray[] = '/'.$value['woord'].'/i';
$escapeNamesReplace[] = '<span style="color: gray;">'.$value['vervanging'].'</span>';


When I want to replace the word "Hello" to "Hey", everything is working fine. But when I place the word "Hello" between brackets, for example:


The word "Hello" is replaced aswell. How can I change the pattern of the preg_replace function to ignore words between brackets?

Wrap Words Or Words Sequences Which Have Not Been Already Wrapped?

I'm trying to wrap words and words sequence from a given list with preg_replace. It almost works, but there are some use cases it doesn't and I can't figure it how. For instance I do this:

// sort by descending length
usort($this->_keywords, function($a,$b){return(strlen($a)<strlen($b));});
// wrapper is -%string%-


From this keyword list:

I'd like to result in:

consectetur adipiscing elit. Phasellus

Organize Words So Can Fit The Most Number Of Words In A Given Length?

I'm looking for a way to do the following. I have a list of words of various char lengths. I have a limited number of chars I can use in a given strings size. I'd like to organize the words to fit as many of them as I can in a given string without going over the limit or cutting any of the words off.



I have a limit of 140 characters to fit them all in, including spaces. If I have more names than space avail in that string, I'd like to generate another string using the same function as described above until all the names in the list are used.

Removing Whitespaces

I try to remove whitespaces from a string using the preg_replace function

preg_replace("/[ ][ ]*/"," ",$string);

This works great, but makes no handles all characters in the same way. I
want to preserve data between double quotes. So,
hello world "It is a sunny... world"
shall be reduced to
hello world "It is a sunny... world"

and should not remove the whitespaces between the quotes.
