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.

Example:

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.

[code]....

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.

if(strlen($img_keyword)>30){
$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>';

[code]....

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:

[code]...

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%-

[code].....

From this keyword list:

lorem
ipsum
sit amet

[code]....

I'd like to result in:

-Lorem- -ipsum- dolor -sit amet-,
consectetur adipiscing elit. Phasellus
rhoncus venenatis orci sed porta. Sed

[code]....

Limiting Number

i'm working on an event listing site. when someone lists an event, they can upload 3 images. Rather than uploading every single image to a single directory, i'd like to break the uploaded images out into a bunch of different directories. otherwise, any attempts to view the contents of the user image folder could result in a really LONG wait as we list a billion images. I'd like to limit the contents of any given directory to a thousand items.

I'd also like to support a very large number of events and images (1 billion? 10 billion?). I realize that many images might overload a single drive on any server, but am still determined to do it. Seems to me that some sort of recursive function might be necessary? It's easy enough to turn an event id into a folder. it's also not so hard to make a new subdirectory so there are no more than 1,000 events in a irectory. what's more difficult is when we exceed 1 million images. then my top level directory would have more than a thousand images in it.

Limiting Text

I have a field in my database named about and I want to limit the amount of characters outputted (to 100)of this, so I thought it would be done like so:

<?php

$query = mysql_query("SELECT * FROM players ORDER BY RAND() LIMIT 1") or die(mysql_error());
$text = substr($about,0,100);


while($row = mysql_fetch_array($query)) {

echo '<h3>'. $row['player_name'] .'</h3>'."
";
echo '<div class="profile_image"><img src="images_two/odhiambo_delete.jpg" /></div>'
echo '<div class="profile_text">'. $row['text'] .'</div>'."
";

}
?>

However, that does not seem to work, where am I going wrong?

Limiting A Selection

I have a table in my database that contains fields relating to addresses. What I want to do is to give the user a choice to view all the locations from a certain county. As there can be multiple instances of a county in the table how do I ensure the county only gets displayed once. For example in the table I may have 5 entries which are:

Devon
Cornwall
Devon
Devon
Sommerset

When I retrieve all the information from the table I want to display only

Devon
Cornwall
Sommerset.
