[PHP-DB] Im seeking a solution to check for duplicate entries with an other sequence
Hello,
I have a question currently i'm programming a function to remove duplicates
from an array of sentences.
The computer must classify sentences with exactly the same words in it, but
with a different sequence as a duplicate.
The array that i use as a feed is as following:
$sentences[] = this is a example sentence;
$sentences[] = a this is example sentence;
$sentences[] = example this is a sentence;
$sentences[] = this is a example sentence for a function;
I want the computer to keep only two records of the sentence array in this
case (0|1|2) and 3
I made the script as following:
function($sentences) {
foreach($sentences as $sentence) {
$words = explode( ,$sentence);
$sentenceArray[] = $words;
}
foreach(sentenceArray as $sentence) {
// Here i want the same words are in other sentences
}
}
My question is how could i check the $sentence array if there are records in
it with exactly the same words
as my feed?

Hello,
Theres this project that I am working on, and a specific module does take
few secs to process, I am thinking it would be cool to be showing a progress
bar(some kind on a .gif image) while the script runs, does any one have an
idea how to implement this?
Thanks,

This isn't really database related, but ok...
?php
// Progress.php
class Progress {
public function start () {
echo file_get_contents ('progress.html');
flush ();
}
public function end ($url) {
$text = script type=\text/javascript\;
$text .= window.location = '$url';;
$text .= /script;
echo $text;
flush ();
}
}
?
?php
// process.php - process the stuff
$progress = new Progress();
$progress-start();
// ... Do your processing here ...
$progress-end('nextpage.php');
?
In the progress.html file, it would just be an html page that has an animated
gif (and whatever else you want on it). Hope this helps.

}
);
// Show the reduced sentences.
print_r($Reduced);

outputs ...
Array
(
[0] = this is a example sentence
[3] = this is a example sentence for a function
)
