Retrieving text between ...

[shachi]

Hello everyone,

I am new to PHP so please excuse me for any mistakes I make in this part of the forum. What I wanted to know is that can't I retrieve the text between special characters from a seperate file?? For e.g. I have a file called test.txt which has the following contents:

=== Title ===

This is a test page with a title in bold.

=== Title2 ===

This is another test with second title.

Now I want to retrieve that file with PHP and get ONLY the text between the starting === & === the ending. Any ideas how I can achieve that??

I am using dokuwiki and want to get the section title by the way.

Any helps would be greatly appreciated.

Why don't you just put them in separate text files? I'm a Bit confused at what your trying to say. But try that.
The code to insert the text in a txt file is

file_get_contents('YourFile.txt')

Happy To Help,
Joe

function getHeaders($content, $delimiter = '===') {
  $tc = $content;
  $titles = array();
  while(strpos($content, $delimiter) !== false) {
    $cttl = $tc;
    $cttl = substr($cttl, strpos($cttl, $delimiter) + strlen($delimiter));
    $cttl = substr($cttl, 0, strpos($cttl, $delimiter));
    $cttl = trim($cttl);
    array_push($titles, $cttl);
    $tc = substr($tc, strlen($cttl) + strlen($delimiter));
  }
  return $titles;
}

function getSection($content, $section) {
  $tc = $content;
  $tc = substr($tc, strpos($tc, $section . ' ===') + 4);
  $tc = substr($tc, 0, strpos($tc, '==='));
  return $tc;
}

$fc = file_get_contents("file.txt");
$ttls = getHeaders($fc);

I wrote getSection() before I read your post properly, but figured you'd probably want it later on so I left it in there anyway.

Untested.

Thanks Twey, let me try that and thanks joe for you response, I will try to make it clearer later on after I test this code Twey posted.

Twey I am continuously getting an error which says:


Fatal error: Allowed memory size of 12582912 bytes exhausted (tried to allocate 35 bytes) in /var/www/html/shachi/testget.php on line 10

Where the blue part keeps on changing(as the content in the file file.txt keeps on increasing).

Thanks.

Ah, that's because the file is too big to read into memory. You'll have to devise some method of splitting it into chunks.
