continue loop

[mraza]

hi i am stuck in a loop please can someone check what is miss. I wants to quit from loop and go to next title if that tile is found but cant figure out how should i go. my code:

$feed_url = "http://www.myfeed.com/feed/";
$xml = simplexml_load_file($feed_url);
foreach ($xml->channel->item as $item) { 

$ns_content = $item->children('http://purl.org/rss/1.0/modules/content/');
$title = $item->title;
// opening file which contain titles already
$content = file('file.txt');
foreach ($content as $aline) {
    if (strstr($title, $aline)) {
        $found =  true;
    } 
}
// i dont wants to print that $title which is already in file.txt so loop continue.
	if($found) {
	continue;
	}

echo $title . "<br>" ;

}

 

Problem is with that continue statement if a title is matched from file.txt it will display me nothing, i only wants to skip that title and echo other titles. thanks for any help

what results are you currently getting? what's wrong?

[mraza]

if a title is matched from file.txt it does not display any result, it shows a blank page, i wants it like if a title is matched it will skip that title and display other.

There are better ways to do this, if the titles are actually identical then it will be even easier, but your problem is that once $found is set to true it is always true.  You need to set it to false at the beginning of the loop somewhere.

thanks but it is not showing anything either

$found =  false;
foreach ($xml->channel->item as $item) { 
$ns_content = $item->children('http://purl.org/rss/1.0/modules/content/');
$title = $item->title;
$content = file('file.txt');
foreach ($content as $aline) {
    if (strstr($title, $aline)) {
        $found =  true;
    } 
}
	if($found){ 
	continue;
	}

	echo $title . "<br>" ;


}

it display only a blank page. if i remove continue; it shows me all titles from feed without problem. in my file.txt all titles are on a new line so are identical.

foreach ($xml->channel->item as $item) {
   $found =  false;

 

But like I said if the titles are identical then this is easier and faster:

 

$feed_url = "http://www.myfeed.com/feed/";
$xml = simplexml_load_file($feed_url);
$content = file('file.txt');

foreach ($xml->channel->item as $item) { 
  $title = $item->title;

  if(!in_array($title, $content)) {
    echo $title;
  }
}

hm thanks again sir but for some reason !in_array is also not working properly, if there is title in file it still display title with above code.

in my other script what i do is run the script and save that title of feed in a file here is code

$ourFileName = "file.txt";
$ourFileHandle = fopen($ourFileName, 'a') or die("can't open file");
fwrite($ourFileHandle, "$title\n");
fclose($ourFileHandle);

so it save that title in file.txt so next time when i run above script it should not read that feed again which has same title in file.txt, is there are any other thing i can try? thanks again

[AbraCadaver]

You can try this.  If it doesn't work then that means they are not identical:

 

$content = file('file.txt', FILE_IGNORE_NEW_LINE);

[mraza]

thank you very much sir this works

$content = file('file.txt', FILE_IGNORE_NEW_LINE | FILE_SKIP_EMPTY_LINES);

 

thx
