mobileka / liner example snippets



$liner = new Liner('path/to/a/file'); // or SplFileObject instance

// Read the whole file
$liner->read();

// Only the first line
$liner->read(1);

// Only the second line
$liner->read(1, 1);

// Read 100 lines starting with the 6th line
$liner->read(100, 5);

// You can also pass a closure as a third argument to mutate the result without iterating over it
// Here's how you can read a CSV file:
$csvAsArray = $liner->read(0, 0, function($file, $line) {
    $line = trim($line);
    return explode(',', $line);
});

// A line will be ignored if modifier returns null
$anEmptyArray = $liner->read(0, 0, function($file, $line) {
    return null;
});

// almost forgot to mention that you can get the number of lines
$liner->getNumberOfLines();

// and that you can also delegate methods to SplFileObject (is it a good idea though?)
$liner->eof();
$liner->rewind();
