ficheros y substrings

[starlightphp]

Al final decidí hacerlo a la aventura. Copio el código que quizás a alguien le sea útil en algún futuro =)
$Fichero = file("fichero.txt"); //Open the file
foreach ($Fichero as $i => $line){ //For each row read.....

Código PHP:

preg_match_all('/;/', $line, $Results, PREG_OFFSET_CAPTURE); //looking for ; contained in $line. This array is kept in $Results
    //print_r($Results);
    foreach($Results as $position){ 
        $position[0] = $position[2][1]+1; //This is the start position for the date
        $position[1] = $position[3][1]; //This is the end position for the date
        $position[2] = $position[8][1]+1; //This is the position in which the balls start
        $position[3] = $position[9][1]; //This is the position in which the balls ends
        $position[4] = $position[10][1]+1; //This is the position in which the reintegro start
        break;
    }   
    $size_date=$position[1]-$position[0]; //Max date size that we are going to substring
    $size_balls=$position[3]-$position[2];  //Max balls size that we are going to substring
    echo substr(strip_tags($line), $position[0], $size_date);
    echo " ";
    echo substr(strip_tags($line), $position[2], $size_balls);
    echo " ";
    echo substr(strip_tags($line), $position[4], 1);
    echo '</br>';
