Question

I am trying to make a news feed type thing in php.

I have a text file – news.txt and a php file index.php.

I have done the surrounding code and opening/closing the text file. Now I am stuck how to insert the new news item $newsnew to the top of the news.txt file and how to delete the old bottom news file in the news.txt file.

Is there any way to do this without deleting the whole file and writing it all again?

EDIT: Each news item is just a small string, say 500 characters, a single line.

Answer 1

Use the file() function to import the items in news.txt as an array, and use array_unshift() to add the new first item, and array_pop() to remove the last item. Join the array back into a single string and write it to news.txt:

$items = file('news.txt');
array_unshift($items, 'New item 1');
array_pop($items);
$newstext = implode(PHP_EOL, $items);
// write $newstext to the external file
