see aantarrão is a word and below it are the synonyms, I can’t think of a way to get the word and the synonyms on an associative array, this is what I’m trying to do:

<?
$file = file('library.txt');
$array_sinonimos = array();
foreach($file as $k)
{
    $explode = explode($k, "|");
    if(is_int($explode[1]))
    {
        $word = $explode[0];
    } 
}
?>

nothing, lol, what can I do here ? loop lines until I find an empty line then try to get a new word with the explode ?, help !

Answer 1

Here’s some code I cooked up that seems to work.

See the code in action here: http://codepad.org/TVpYgW91

See the code here

UPDATED to read line by line

    <?php 
    $filepointer = fopen("library.txt", "rb");
 $words = array();

 while(!feof($filepointer)) {
        $line = trim(fgets($filepointer));
        $content = explode("|", $line);
        if (count($content) == 0)
        continue;
        if (is_numeric(end($content))) {
        $word = reset($content);
        continue;
        }

        if (isset($words[$word]))
        $words[$word] = array_merge($words[$word], $content);
        else
        $words[$word] = $content;
    }

    print_r($words);

So what’s the strategy?

1. fix up the line endings
2. run through the file line by line
3. ignore empty lines (count($content))
4. split the line up on the pipes, if the line has a numerical value for the last value, then this becomes our word
5. we only get to the last step if none of the other traps got touched, because of the continue statements, so if it is then just split up the words by the pipe and add them to or create the array element.
