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);
?>

An example for searching text (a word or phrase) in the directory files:


function search_text_in_directory_files($directory, $text){
    if(file_exists($directory)){
        $files = array();
 
        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
");
    }
}
?>

Tags of the file content

Ruben Sargsyan — Mon, 01 Feb 2010 18:54:47 +0000

This function is used for leading out all tags with their counts from the file.


function tags_in_the_file($file){
    if(file_exists($file)){
        $content = file_get_contents($file, true);
 
        preg_match_all("/(<([\w]+)[^>]*>)/", $content, $matches, PREG_SET_ORDER);
 
        $tags = array();
        $tags_count = 0;
 
        foreach($matches as $tag){
            $tag_found = false;
 
            if(!empty($tags)){
                for($i=0; $i<count($tags); $i++){
                    if($tags[$i]["tag"]==$tag[2]){
                        $tags[$i]["count"]++;
                        $tag_found = true;
                        break;
                    }
                }
            }
 
            if(!$tag_found){
                $tags[$tags_count]["tag"] = $tag[2];
                $tags[$tags_count]["count"] = 1;
 
                $tags_count++;
            }else{
                $tag_found = false;
            }
        }
 
        return $tags;
    }else{
      return false;
    }
}
 
$file = "test.html";
 
$tags = tags_in_the_file($file);
 
if($tags!==false){
    foreach($tags as $tag){
        echo("".$tag["tag"]." - ".$tag["count"]."
");
    }
}else{
    echo("File not found!");
}
?>

the test.html content:

<html>
 
<head>
  <title>Tags of the file content</title>
</head>
 
<body>
 
<span id="hello">Hello</span> <span id="world">world</span>.
 
<p>My personal website is <a href="http://rubensargsyan.com">http://rubensargsyan.com</a></p>
 
</body>
 
</html>

Output:

html – 1

head – 1

title – 1

body – 1

span – 2

p – 1

a – 1

If the file is not found the function return false.

Write rss to a file

Ruben Sargsyan — Mon, 07 Dec 2009 13:00:56 +0000

This function is used for writing rss to a file.


function rss_to_file($url,$file){
  $rss = simplexml_load_file($url);
 
  if($rss){
    $text = "";
 
    $text .= $rss->channel->title."\r\n \r\n \r\n";
 
    $items = $rss->channel->item;
 
    foreach($items as $item){
        $title = $item->title;
        $link = $item->link;
        $published_on = $item->pubDate;
        $description = $item->description;
 
        $text .= $title."\r\n";
        $text .= $published_on."\r\n";
        $text .= $description."\r\n \r\n";
    }
 
    $handle = fopen($file, 'w');
    fwrite($handle, $text);
    fclose($handle);
  }
 
  return false;
}
 
$url = "http://rubensargsyan.wordpress.com/feed/"; // Rss url
$file = date("Y-m-d").".txt"; // The file
 
rss_to_file($url,$file);
?>

If the rss url is wrong the function return false.
