Automatically put words for autocompleting

Ruben Sargsyan — Fri, 25 Jun 2010 11:30:27 +0000

While I was looking through a site about migrate sharepoint, I saw a search field with autocompleting and the first idea I have is to develop a code that will automatically put those words for autocompleting that are more often happen in the texts.


function get_words($texts){
    if(!empty($texts)){
        $words = array();
        $words_count = 0;
 
        foreach($texts as $text){
            preg_match_all("/\w{2,}/i", $text, $matches, PREG_SET_ORDER);
 
            foreach($matches as $word){
                $word_found = false;
 
                if(!empty($words)){
                    for($i=0; $i<count($words); $i++){
                        if($words[$i]["word"]==$word[0]){
                            $words[$i]["count"]++;
                            $word_found = true;
                            break;
                        }
                    }
                }
 
                if(!$word_found){
                    $words[$words_count]["word"] = $word[0];
                    $words[$words_count]["count"] = 1;
 
                    $words_count++;
                }else{
                    $word_found = false;
                }
            }
        }
 
        return $words;
    }else{
      return false;
    }
}
 
function sort_by_words_count($word1,$word2){
  $word1_count = $word1["count"];
  $word2_count = $word2["count"];
 
  if($word1_count<$word2_count){
    return 1;
  }elseif($word1_count==$word2_count){
    return 0;
  }else{
    return -1;
  }
}
 
$text1 = "If you would like to have your running line on your Wordpress blog, so this plugin is just for you! It gives you the possibility to show one of the posts from your chosen category by the running line. So download and enjoy!";
 
$text2 = "This plugin is used when there are words, words expressions or sentences to be explained in the posts or pages of your wordpress blog. This plugin will help the visitors to read the explanations of the words (words expressions,sentences) you need via tooltips.";
 
$text3 = "Any occasion to receive greetings? So, this plugin is just for you! This Widget plugin shows a greeting image which would be uploaded for the occasion and a pop up form for receiving the greetings. It is possible to show the greetings in any post or page.";
 
$text4 = "This plugin adds links after the posts for subscribing to the post author's posts feed via RSS. So if there are several authors in the blog, but a visitor wishes to subscribe just an author posts feed, this plugin gives that possibility to do it.";
 
$text5 = "This is a widget plugin which helps to display the visitors who left the most number of comments in the Wordpress blog.";
 
$texts = array($text1, $text2, $text3, $text4, $text4);
 
$all_words = get_words($texts);
 
usort($all_words, 'sort_by_words_count');
 
$autocompleting_words_count = 10; // Autocompleting words count
 
for($i=0; $i<$autocompleting_words_count; $i++){
    $autocompleting_words[$i] = '"'.$all_words[$i]["word"].'"';
}
 
$autocompleting_words = implode(",",$autocompleting_words);
?>

Move JavaScript codes from a file to an other file

Ruben Sargsyan — Wed, 26 May 2010 09:06:26 +0000

An example to move the JavaScript codes from a file to an other file:


function moveJavascriptCodes($fromFile,$toFile){
    $fileText = file_get_contents($fromFile);
 
    preg_match_all("#]*>(.*?)#si",$fileText,$javascriptCodes,PREG_SET_ORDER);
 
    $codes = array();
 
    foreach($javascriptCodes as $javascriptCode){
        $codes[] = $javascriptCode[1];
    }
 
    if(file_put_contents($toFile,implode("\n",$codes))===false){
        return false;
    }
 
    return true;
}
 
$fromFile = "totalCode.php"; //The file from which JavaScript code will be got
$toFile = "javascriptCode.js"; //The file into which JavaScript code will be set
 
moveJavascriptCodes($fromFile,$toFile);
?>

        if($handle=opendir($directory)){
            while(($file=readdir($handle))!==false){
                if($file!="." && $file!=".." && !is_dir($directory."/".$file) && file_exists($directory."/".$file)){
                    $file_content = file_get_contents($directory."/".$file);
 
                    if(preg_match("/".$text."/i",$file_content)){
                        $files[] = $file;
                    }
                }
            }
            closedir($handle);
        }
 
        return $files;
    }
 
    return false;
}
 
$directory = "files";
$text = "text";
 
$found_files = search_text_in_directory_files($directory,$text);
 
if($found_files===false){
    echo("Directory Not Found");
}elseif(empty($found_files)){
    echo("Text Not Found");
}else{
    foreach($found_files as $found_file){
        echo("$found_file
");
    }
}
?>

An example for sorting texts in array by matching the word in them:


$word = "plugin";
 
function sort_by_matching_word($text1,$text2){
  global $word;
 
  $text1_matched_words_count = preg_match("/\b".$word."\b/i",$text1);
  $text2_matched_words_count = preg_match("/\b".$word."\b/i",$text2);
 
  if($text1_matched_words_count<$text2_matched_words_count){

Highlight words in a text

Ruben Sargsyan — Fri, 20 Nov 2009 11:11:49 +0000

This function is used to search and highlight words from the text.

function highlight_words($text,$word){
   $text = preg_replace('/\b'.$word.'\b/i', '$0', $text);
   return $text;
}

Note to that if the searched word is in the structure of the other wordform (for example the word “stand” is in the structure of the word “understand”), so the word will not be highlighted. It will be highlighted when after or before the word is not appeared alphabetic or digital character or underline (_) character. The function also ignores case sensitivity of the word. If the searched word is “light”, the words “highlight”, “light_faced”, “lighten”, “light9″ e.t.c. will not be highlighted as well.

Example:

Searching the word “book” in the text “Our book-keeper was bought an interesting book from bookshop. Book name is My big book.”


function highlight_words($text,$word){
   $text = preg_replace('/\b'.$word.'\b/i', '$0', $text);
 
   return $text;
}
?>
 

 

$word = "book";
$text = "Our book-keeper was bought an interesting book from bookshop. Book name is My big book.";
 
echo(highlight_words($text,$word));
?>

The above example will output:

Our book-keeper was bought an interesting book from bookshop. Book name is My big book.

You see that the word “book” of the wordform “bookshop” was not highlighted, and the words “book-keeper”, “book”, “Book” and “book” which is followed by the punctuation mark “.” was highlighted.

Set your style to the highlighted words in .highlight{ … }.

The demo you can see here.
